What is lecithin? You are probably familiar with the word. In fact, you may even be taking it as a supplement. But what is lecithin really? Where does it come from? And what can it do for you? ‘What is lecithin?’ and other such questions are what we are going to tackle in this article.

What is Lecithin?

Actually the term lecithin connotes two meanings that are somewhat related but are not used in the same sense. In biochemistry and other related science, lecithin is a synonym for phosphatidyl choline. It is the main lipid component in biological membranes, like our cell membranes or cell walls of plants. On the other hand, commercial lecithin is actually a natural mixture of neutral and polar lipids, including glycolipids, triglycerides, sterols, and small quantities of fatty acids, carbohydrates, and sphingolipids. The polar lipid Phosphatidyl choline is present in commercial lecithin in concentrations of 20 to 90%.

Where does lecithin come from?

After asking what is lecithin, you want to know where it is found. Lecithin that contains phosphatidyl choline is produced mainly from vegetable sources, although it may also be found in animal and microbial sources. Majority of commercial 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, then you probably know already that the substance is synthesized by the body from food. This means that it is not an essential nutrient, since the body can always get its supply of lecithin from its diet. This is also one of the reasons why hardly anyone ever suffers a deficiency in lecithin. Still, having a steady supply of lecithin for our body’s use is good, if only to take advantage of the benefits it has to offer.

Lecithin is naturally found in the foods that we eat, especially rich foods, such as egg yolk, soybeans, grains, wheat germ, fish, legumes, yeast, peanuts, etc. The compound can also be found as supplement sold to the public. Lecithin capsules, powder, or granules are sold in many food and drug stores, often marketed as weight loss promoting supplements for dieters and weight loss enthusiasts. In addition to that, lecithin is also taken in a pill form or mixed into health shakes.

What is lecithin’s claim to health?

The following are some of the many health claims that lecithin is said to have:

* Cardiovascular health

* Liver and cell function

* Fat transport and fat metabolism

* Reproduction and child development

* Treatment for gallstones

* Improvement in memory, learning and reaction time

* Healthy hair and skin

* Cell communication

* Physical performance and muscle endurance

... oil. The nutrient was found as a by product of the degumming process What is Lecithin of soybean oils. The Structure of Lecithin: Egg Yolk There are differences in the structure of lecithin derived from egg yolk and those derived from plants, such as soy lecithin. First, the structure of lecithin derived from egg yolk is essentially composed of triglycerides and phospholipids, which differs considerably from plant lipid mixtures. Egg yolk lecithin contains long chain polyunsaturated fatty acids known as LC-PUFAs or Arachidonic Acid and Docosahexaenoic Acid. Both are bound phospholipids, the former occurring exclusively in cell membranes while the latter is found in high amounts in optic nerve membranes. In the structure of lecithin derived from egg yolk, arachidonic acid is involved in signal transduction and ensures high membrane fluidity. It is important for body weight development. On the other hand, docosahexaenoic acid...

Lecithin Weight Loss
The term is often synonymous to phosphatidyl choline (PC), which many in the scientific community use to refer to lecithin. Lecithin, the Emulsifier One of the many functions of lecithin is emulsifying fats. In the body, lecithin is present in bile, a digestive substance produced by the liver and stored in the gall bladder to aid in digestion. It is critical for the absorption of fats and fat-soluble vitamins in the small intestine and serves as a major route for eliminating cholesterol. The presence of lecithin in bile is primarily to keep the fatty acids from mixing with other organic molecules also found in bile, such as bile acids, cholesterol, phospholipids, and bilirubin. By acting as an emulsifying agent, lecithin ensures that bile does all its functions smoothly. Lecithin, the Aid to Fat-Burning Another function of lecithin is to...

Lecithin - Its Composition and Functions In biochemistry, lecithin is often used synonymously What is Lecithin with another term, phosphatidylcholine, which is actually one of the three main types...

Soy Lecithin Allergens
... membrane has led many scientists to conduct investigations on 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 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 What is Lecithin evidence of the benefits of lecithin, there is little in the way to show a real connection between improved conditions and the taking of lecithin supplements. Instead, what doctors have observed is a concerning number of reports of soy lecithin allergens. Soy Allergy In line with the increasing use of soy products...

Liquid Lecithin
... is to increase the rate at which fat is burned to produce energy for the body. Lecithin is contained in the bile, which is a kind of substance produced by the liver and stored in the gallbladder necessary for digestion. As an emulsifier, the function of liquid lecithin is to separate the fatty acids in the bile and protect them from the ravages of oxidation. The compound also helps keep the liver cells healthy so they can continue What is Lecithin doing their function of filtering and cleansing the blood of all toxins and harmful molecules. Sources Liquid lecithin can be found in nearly all kinds of food. But the richest sources of liquid lecithin are those that are high in fat and cholesterol, such as eggs, red meat, organ meat, etc. Soybeans are also good...

Health Lecithin
... supplements are taken. Why is it Good? As a phospholipid, lecithin is both phosphorus and fats (lipids). As such, it is an excellent source of essential fatty acids, which are a part of each molecule. Because phospholipids are both fat loving (lipophilic) and water loving (hydrophilic), lecithin helps protect the cell's essential fatty acids, which are polyunsaturated and extremely vulnerable to oxidation. By taking in health lecithin supplements, especially in the form of granules, we can help protect the essential fatty acids in our bodies, keeping them from turning rancid and start harming other healthy cells. Another health lecithin benefit is its role as one of the special chemicals that easily crosses the blood-brain barrier. Not only is lecithin permeability necessary for the metabolic processes that are occurring in all cells but also, it provides for the constant regeneration of the...

Benefits of Lecithin
... market come from soybeans. Lecithin - Its Benefits Lecithin is regarded in the scientific community as a synonym for phosphatidyl choline (PC), which is said to be the main compound responsible for all the benefits of lecithin, specifically its medicinal effects. When we consume phosphatidyl choline, the compound is broken down into the nutrient choline, which many consider as an essential nutrient. "Essential" because our bodies cannot manufacture their own supply of choline and instead we have to depend on the foods that we eat to maintain the right levels. Lecithin is an essential component in the cell membrane. In fact, it defines its structure. As such, one of the benefits of lecithin is to maintain the integrity of cell membranes, helping facilitate the movement of fluids inside and outside the cell. As a component of bile, lecithin keeps fats emulsified. You have noticed how fats...

Lecithin Supplements
... a variety of diseases from lowering high blood cholesterol, to reducing heart attacks and stroke, atherosclerosis, dispelling symptoms of cirrhosis of the liver and gall stones, and improving memory loss. Lecithin supplements are even currently marketed as aids to weight loss. However, it should be noted that phosphatidyl choline itself is not an essential nutrient. Our bodies already have it and can produce more of it should the need arise. Choline, on the other hand, can only be derived from the foods we eat. A deficiency in this compound could lead to various debilitating diseases, not least of which is cirrhosis of the liver. The good thing about it is that phosphatidyl choline is normally What is Lecithin synthesized by the body to form choline, so taking in lots of lecithin supplements containing a high percentage of the compound could help boost your supply of choline and...

Soy Bean Lecithin
... bean lecithin? The answer is simple: because this compound is so vital to our body that we cannot afford to have inadequate supply. Soy bean lecithin was first discovered in the 1930s when the compound was extracted from sludge, a by product of soybean oil processing. Of course, decades before that, lecithin was already found in egg yolk and most of the commercial lecithin sold in the market that time was egg lecithin. But then with the emergence of soy bean lecithin, a shift also occurred. Lecithin that is derived from plant, such as soy bean lecithin, is regarded as safer to use than those extracted from animals since animal lecithin is often excreted by the kidney, which contains toxins and other harmful substances. As such, soy bean lecithin came to...

Soy Lecithin
... earlier, soy lecithin is a by product of soybean processing. At first, the soybeans are tempered by keeping them at a consistent temperature and moisture level for approximately seven to 10 days. This has a hydrating effect on the soybeans, loosening it from its hull. Then, the soybeans are cleaned and cracked into small pieces. The What is Lecithin cracked beans are separated from the hulls and are heated and pressed into flakes. Next, the flakes undergo a distillation process where the soybean oil is extracted, after which crude soy oil is made to undergo a "degumming" procedure. The sludge that is produced as a result is where soy lecithin comes from. Of course, the sludge would have to undergo another process first, to extract the lecithin. The waste product usually contains solvents and pesticides that could be harmful if not purified through a process called the...
