Choline

Uncommon card · No. 87986

Choline is a cation with the chemical formula [(CH3)3NCH2CH2OH]+. Choline forms various salts, such as choline chloride and choline bitartrate. An essential nutrient for animals, it is a structural component of phospholipids and cell membranes. Choline is used to synthesize acetylcholine, a neurotransmitter involved in muscle control and numerous functions of the nervous system. Choline is involved in early development of the brain, gene expression, cell membrane signaling, and brain metabolism. Although humans synthesize choline in the liver, the amount produced naturally is insufficient to meet cellular functions, requiring that some choline be obtained from foods or dietary supplements. Foods rich in choline include meats, poultry, eggs, fish, cruciferous vegetables, and beans. Choline is present in breast milk and is commonly added to infant formulas.
