Choline (/ˈkoʊliːn/ KOH-leen)[4] is an essential nutrient for humans and many other animals, which was formerly classified as a B vitamin (vitamin B4).[5][6] It is a structural part of phospholipids and a methyl donor in metabolic one-carbon chemistry. The compound is related to trimethylglycine in the latter respect. It is a cation with the chemical formula [(CH3)3NCH2CH2OH]+. Choline forms various salts, for example choline chloride and choline bitartrate.
