Choline occurs as quaternary saturated amine with the chemical formula
in which X- occurs as counterion like atomic number 17 (watch choline chloride), hydroxide or tartrate. Choline was found by Strecker inside 1862 and chemically synthesized in 1866. Around 1998 choline was classified as an essential nutrient by the Food and Nutrition Board of the Institute of Medicine (U.S.A.) & Adequate Intakes (AI) own been established. Choline & its metabolites come required for triplet independent physiologic purposes: structural integrity & signal roles for cell membranes, cholinergic neurotransmission (acetylcholine synthesis), and as a major source for methyl-groups via its metabolite, betaine that participates in the S-adenosylmethionine synthesis pathways.
