Анотація до тексту Choline
Although choline is not by strict definition a vitamin, it is an essential nutrient. Despite the fact that humans can synthesize it in small amounts, choline must be consumed in the diet to maintain health. The majority of the body\'s choline is found in specialized fat molecules known as phospholipids, the most common of which is called phosphatidylcholine or lecithin.
Men and women fed intravenously (IV) with solutions that contained adequate methionine and folate but lacked choline have developed a condition called \"fatty liver\" and signs of liver damage that resolved when choline was provided. Choline is required to form the phosphatidylcholine portion of very low density lipoprotein (VLDL) particles.
Very little information is available on the choline content of foods. Most choline in foods is found in the form of phosphatidylcholine. Milk, eggs, liver, and peanuts are especially rich in choline. Phosphatidylcholine, also known as lecithin, contains about 13% choline by weight.
