wat is lecithin?what it contains?where can it be found?thanx?

Answer 1

Lecithin is mostly a mixture of glycolipids, triglycerides, and phospholipids (e.g. phosphatidylcholine, phosphatidylethanolamine, and phosphatidylinositol). However, in biochemistry, lecithin is usually used as a synonym for pure phosphatidylcholine, a phospholipid which is the major component of a phosphatide fraction which may be isolated from either egg yolk (in Greek lekithos—λεκιθος) or soy beans from which it is mechanically or chemically extracted using hexane.

Lecithin is commercially available in high purity as a food supplement & for medical uses.
Nervous and circulatory lecithin is produced by the liver if the diet is adequate. It is needed by every cell in the body and is a key building block of cell membranes; without it, they would harden. Lecithin protects cells from oxidation.

Lecithin is used commercially in substances requiring a natural emulsifier and/or lubricant, from pharmaceuticals to protective coverings. For example, lecithin is the emulsifier that keeps cocoa and cocoa butter in a candy bar from separating.

Answer 2

Lecithin definition:
Nutrient containing phosphatidylcholine, found in many animal and plant foods like eggs, soya and wheat and also made by the body. It helps the breakdown of fats and cholesterol. Used to prevent arterial congestion.

Answer 3

lecithin is a phospho lipid one of the classification of lipids called compound lipids (lipid is nothing but fat which is made up of fatty acids and glycerol.)which in addition contain phosphoric acid in the form of phosphotidyl choline.

It is needed by every cell in the body and is a key building block of cell membranes; without it, they would harden. Lecithin protects cells from oxidation.

Found in foods like soybean,sunflower ,eggyolk etc.
