Choline

Choline is an ammonium compound that is commercially available as choline chloride. Choline is contained in nutritional supplements for humans and feed products for animals. In food, it occurs both in free form and bound as lecithin. It is contained in smaller quantities in grain and soya. Choline is a component of the extremely important neurotransmitter (nerve messenger) acetylcholine. It also contributes to normal fat metabolism.
