Ever seen lecithin in action? Well, if you want to, then just place a bar of chocolate inside the freezer and wait several minutes before taking it out again. Study the chocolate bar carefully. Do you see that thin layer of white coating the candy? That is lecithin in action for you.
A Versatile Nutrient
The purposes of lecithin in the commercial sector are varied. It is used as a natural emulsifier and/or lubricant and utilized as an important ingredient for products ranging from pharmaceuticals to protective coverings. But lecithin is powerful not only for these reasons. Lecithin is powerful because it is one of the important nutrients that make up the cell membrane found in the cells of every living organism on earth and plays a vital role in normal cell functions.
Lecithin - Its Composition and Functions
In biochemistry, lecithin is often used synonymously with another term, phosphatidylcholine, which is actually one of the three main types of phospholipids found in the phosphatide fraction isolated from either egg yolk or soy beans. On the other hand, the lecithin used by many food manufacturers is a mixture of these phospholipids in oil, 20% to 90% of which is phosphatidylcholine.
One of the many reasons why lecithin is powerful is because of the presence of phosphatidylcholine. Lecithin that contains this substance is produced from vegetable, animal and microbial sources, but mainly from vegetable sources, the most important sources of which are soybean, sunflower, and grape seed.
In 1998, the US Food and Drug Administration named lecithin as GRAS, or Generally Regarded as Safe, making it one of the few emulsifiers currently sold in the market as such. This is because compared with its synthetic alternatives, lecithin can be totally biodegraded and metabolized. In addition, lecithin is powerful since it is already an integral part of biological membranes, making it virtually non-toxic. Other emulsifiers can only be excreted via the kidneys so they may contain impurities.
Phosphatidylcholine is a mixture of differently substituted sn-glycerol-3-phosphatidylcholine backbones. Chemically, its structure is utterly variable and dependent on fatty acid substitution. Another reason that lecithin is powerful is its role in protecting fatty acids from the damages caused by oxidation.
An essential nutrient, fatty acids are highly vulnerable but greatly needed by the body. They are polyunsaturated fats and are a vital pat of each molecule. By keeping these fatty acids from becoming damaged due to oxidation, phosphatidylcholine or lecithin stabilizes them, keeping them away from harmful substances.
Lecithin is powerful because of its unique structure. It is both fat loving for the fatty acids (lipophilic) and hydrophobic, meaning it will always be moving away from areas with lots of water. This tendency of lecithin to move away from watery areas and towards areas with lots of fats is the reason why lecithin is powerful, especially when it comes to protecting fatty acids. In moving towards the fatty acids and moving away from the watery areas, lecithin molecules form a ring around the fatty acid molecule that keeps it away from oxidation-causing molecules.

Lecithin Benefits
... one of its lecithin benefits, which is to act as an emulsifying agent, making it a convenient ingredient to use in many processed foods. Lecithin for Health While there is little doubt that lecithin is indeed a powerful emulsifier, there is more to lecithin benefits than that. For decades, people have Lecithin is Powerful been touting that treatment for high cholesterol is one of the many lecithin benefits. There is little evidence to support this claim, mostly because when the studies conducted were largely unreported. Still, these claims about lecithin benefits on high cholesterol may have something to do with the fact that lecithin, specifically phosphatidylcholine, appears to have the ability to disperse cholesterol in the blood, thus keeping them from sticking to the walls of our arteries. In doing this, lecithin may also help prevent atherosclerosis. Another one of the lecithin benefits is that it displays potential as...
Health Lecithin
... and more of the health lecithin benefits may be uncovered. Where Lecithin Comes From Lecithin is found in many of the foods we have for our daily diet. However, if you want foods that are rich in lecithin, then turn no further from those same foods that are high in cholesterol and fats. The most concentrated sources of dietary lecithin are organ meats, red meats, and eggs, which is where lecithin got its name by the way - lekithos, Greek for "egg yolk." But with today's current trend in low-fat, low-calorie diet, many have turned away from lecithin-rich foods. This reduction may likely result in an inadequate dietary intake of lecithin and choline, a component of lecithin. In order to make up for the lecithin lost through reduction of egg consumption, organ meats, and red meats, health...
Lecithin Sources
... other lecithin sources, over and above the normal diet. Soy Foods One of the most popular lecithin sources is soy. In fact, most lecithin sources sold commercially today are derived from soybean oil. In the United States, soy food consumption is increasing annually. This may help to increase the level of lecithin consumption. Soy food is one of the most versatile of lecithin sources. The soybean can be eaten whole after it has been boiled or roasted. It can also be transformed into a great variety of foods, the more popular of which are tofu, meat alternatives, soy sauce, soy flour, and soybean oil (usually called vegetable oil). Supplements Another alternative Lecithin is Powerful to getting adequate supply of lecithin is supplementation. Supplements are excellent lecithin sources; one tablespoon of lecithin granules contains as much as a 1, 725 mg/serving. A soft gel capsule of lecithin supplement may contain less at 180 mg/serving. The concentration of lecithin in supplements varies according to its form. According to many sources,...
Benefits of Soy Lecithin
... of phospholipids, which are a class of fat and water soluble compounds. The phospholipids found in soy lecithin are: phosphatidylcholine (PC), phosphatidylinositol (PI), and phospathidylethanolamine (PE). The benefits of soy lecithin can be traced back to the presence of phosphatidylcholine and its synthesized form, choline. Phosphatidylcholine, a Powerful Emulsifier One of the main functions of soy lecithin is to act as Lecithin is Powerful an emulsifier inside or outside the body. Outside, it is used commercially to keep chocolates, candy coatings, margarine, butter, and a whole lot more. It is even used in the pharmaceutical industry as well as various other industries that produce materials such as paint, textile, to name a few. On the other hand, if talking about the benefits of soy lecithin inside the body, then we have to take into account the role that phosphatidylcholine plays in the living cell. As a phospholipid, phosphatidylcholine is a major...
Effect of Lecithin
... purpose of lecithin is still a great emulsifier. What is more, it is also one of the safest. In 1998, the US Food and Drug Administration named lecithin as one of the few emulsifiers currently available in the market as generally safe for consumption. For edible applications, the effect of lecithin is astounding. It is normally added to such food products as shortenings, margarines, baked goods, chocolate, confectionery coatings, peanut butter, powder mixes, and dietary food. It emulsifiers products that are Lecithin is Powerful high in fats and oils, as well as promotes stabilization, antioxidation, crystallization, and spattering control. Animals may also benefit from the effect of lecithin. The compound is often added to animal feed, mainly for the same purpose of stabilizing products and providing antioxidant properties. Lecithin for Health Lecithin is one of the major components of the cell...
Organic Lecithin
... Besides being used in foods that we generally consume, organic lecithin has also expanded its function to include animal feeds, cosmetics, paints, and metal tape. The compound is even available as a supplement in capsules, pills, or granules. Effects and Benefits There are several functional effects associated with lecithin. First, it is an emulsifier, capable of keeping oils from separating and keeping fat molecules dispersed in food products. This ability of organic lecithin to keep essential oils and disperse fats is the basis of the scientific premise that the compound may have positively affect those with high cholesterol levels Lecithin is Powerful in the blood stream. But while there is very little evidence to prove that scientific claim, there is however enough proof of organic lecithin's emulsifying action to go around the commercial food industry. Lecithin can be used to lower the fat content of some foods at the same time enable them to still taste good. Organic lecithin sold commercially is composed of a naturally occurring mixture of the phosphatides...
What is Lecithin
... lecithins sold in the market today come from soybean (mostly), sunflower, and grape seed. When talking about plant lecithins, the most common source is soybean. When Maurice Gobley, the French scientist discoverer of lecithin, found lecithin in egg yolk in 1950, egg yolk was the sole source of lecithin used by the commercial food industry. However, by the 1930s, the time when soybean lecithin was discovered, egg yolk no longer held its former place of being the major source of lecithin for commercial use. Today, it is not even a major source of lecithin in nutritional supplements. The reason may be that lecithins that come from plants are GRAS or generally regarded as safe. Who needs to take lecithin? When you know all there is to know about what is lecithin,...
Lecithin Effects
... lecithin, the compound of lipid and phosphate acid mixtures used in the commercial food industry. However, in chemistry, biochemistry, and other similar sciences, the term takes on a whole different meaning. Often, lecithin is used synonymously with choline, kelecin, lecithol, soy lecithin, vegilecithin, vitrellin, and phosphatidylcholine. Strictly speaking though, choline is actually just a component of lecithin - a major one, that is. Out of the many chemicals found in lecithin, the most important and the most studied is choline. For years, the lecithin effects of choline has been the subject of countless studies and extensive research, all investigating the purported benefits of lecithin. To name a few, lecithin effects have been investigated on the following conditions: dementia, stroke, Alzheimer's Disease, Lecithin is Powerful substance abuse, brain infection, injury to the brain, and spinal cord...
Facts about Lecithin
... lecithin? And what can it do for us? A Phospholipid One of the first facts about lecithin that you ought to know is that it is a phospholipid, one of the many found in all living organisms, including humans. But more than that, lecithin is actually a complex mixture of phospholipids, glycolipids, triglycerides, sterols, and small quantities of fatty acids, carbohydrates, and sphingolipids. Its primary phospholipid components include phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatic acid (PA). Now, since lecithin is present in the cells of all living organisms, you must think and believe that it is an essential nutrient. Certainly, that is what the adverts have been telling us. However, the facts about lecithin will tell you that the substance actually Lecithin is Powerful comes from the diet and is only synthesized in...
Lecithin Side Effects
... cells, scientists believe that lecithin side effects include a possible cure for conditions involving cognition or those that affect the mental processes used to acquire, maintain, retrieve, and utilize information. One example is dementia, which is a mental condition that may due to stroke. It has been observed that people who suffer form this condition often have a low level of a natural chemical known as acetylcholine. One of the chemical compounds found in lecithin is acetylcholine. This compound is actually a neurotransmitter that affects the muscles and memory. The lecithin side effects of supplements, the symptoms of dementia may be improved by increasing the levels of acetylcholine in the body. Another example of the wonders of lecithin side effects is its ability to reduce cholesterol levels in the blood. A small study of individuals with normal or mildly elevated cholesterol levels showed...
Structure of Lecithin
... from soy actually consists of three types of phospholipids: phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylinositol (PI). Since soy lecithin is obtained in the process of degumming crude soy oil, it contains minimal amounts of hydratable compounds (1.8%), comprised primarily of phosphatides. After going through the synthesizing process, the resulting structure of lecithin is 30-35% crude soy oil and 65-70% phosphatides. Oil can then also be removed completely with the addition of acetone. In the structure of lecithin derived from soy, the phosphatides consist of glycerides, which are the basic components of soy oil. However, instead of one fatty acid radical, this has been replaced with phosphoric acid. Now, this is different in the case of pure or chemical lecithin or phosphatidylcholine, where the phosphoric acid is further esterified with choline. But commercially, the structure of lecithin...
Lecithin Weight Loss
... facilitate fat burning makes it a valuable compound in the weight loss and diet community. In fact, the compound is currently marketed as a lecithin weight loss supplement, an alternative weight loss regimen for those who want a diet quick fix. Lecithin is Powerful Of course, lecithin can be naturally found in foods that we eat. Certainly, foods that are rich in lecithin are foods that we often include in our daily diet, such as egg yolk, soybeans, grains, wheat germ, fish, legumes, yeast, and peanuts. However, if these are not enough, lecithin weight loss supplements are also sold in capsule, powder or granular form. Lecithin weight loss supplements are highly filtered. That means they contain less than 35% of phosphatidyl choline while the rest are made of various substances. Majority of these lecithin weight loss supplements are derived from soybeans, although egg yolk lecithin weight loss supplements can also be found. But while lecithin weight loss supplements...

... the role of lecithin in the normal bodily processes. It was found that a component of lecithin, phosphatidylcholine and its synthesized form, choline, are vital to liver health in that they help keep fats in the bile and protect liver cells from the ravages of oxidation. Other studies also showed that choline may play a significant role in the synthesis of Lecithin is Powerful an important neurotransmitter, acetylcholine. This led others to believe that lecithin may help improve the cognitive functions of the brain, even going so far as to help enhance our memories. But while there are quite a number of studies that seem to show evidence of the benefits of lecithin, there is little in the way to show a real connection between improved conditions...
Liquid Lecithin
... or soya beans, this form of liquid lecithin is commercially available in high purity and used for a variety of purposes in the food industry as well as other industries. However, for the most part, liquid lecithin is utilized as an emulsifier, and is in fact one of the limited number of emulsifiers commonly regarded as safe to use. Benefits While lecithin is a natural part of the body, it is, however, not an essential nutrient, unlike fatty acids or amino acid. Our bodies already have lecithin and can manufacture more if needed. What is essential however is the synthesized form of liquid lecithin, which is choline. Our bodies derive choline from phosphatidylcholine component in liquid lecithin. To maintain cell membrane integrity Lecithin is Powerful and facilitate the movement of fats in and out of cells, as well as ions, wastes, and nutrients, we need a constant supply of choline. In addition, the neurotransmitter acetylcholine needs choline for its normal functions. Due to liquid lecithin's choline make up,...

... concentration, and recall. It cleanses the liver and kidneys and helps the body absorbs nutrients. And to top it all off, it adds sprinkle to your salads, favorite drinks, nut butter, spreads or sauces. Yet, for all the wonderful benefits of lecithin, would you believe that it is actually nothing more than a byproduct of soybean processing? Byproduct, meaning it is little more than waste. So how come this purportedly "waste" product contains so many health benefits? What is the theory behind the benefits of lecithin? Lecithin - Its History and Origin The word lecithin comes from the word lekithos, which is Greek for "egg yolk." It was given that name because lecithin was actually first discovered in 1805 when the French scientist Maurice Gobley isolated the compound from an egg yolk. Lecithin is a great emulsifier. Since its discovery, it has been widely marketed in the commercial sector as an emulsifier used mainly in the food...
