choline salicylate

choline /cho·line/ (ko´lēn) a quaternary amine, often classified as a member of the B vitamin complex; it occurs in phosphatidylcholine and acetylcholine, is an important methyl donor in intermediary metabolism, and prevents the deposition of fat in the liver.

choline [ko´lēn]

an amine that occurs in phosphatidylcholine and acetylcholine, and is an important methyl donor in intermediary metabolism. Choline is a lipotropic agent, a substance that decreases liver fat content by increasing phospholipid turnover. It was formerly considered to be a B vitamin and is now classified as a pseudovitamin, although it is still sometimes classified as part of the vitamin B complex. Vitamin B₁₂ and folacin are involved in the synthesis of choline.

choline acetylase (choline acetyltransferase) an enzyme that brings about the synthesis of acetylcholine.

choline

a quaternary amine which occurs in the phospholipid phosphatidylcholine and the neurotransmitter acetylcholine, and is an important methyl donor in intermediary metabolism. It was formerly considered to be a B-vitamin and was used to treat fatty degeneration of the liver.

choline acetylase, choline acetyltransferase

an enzyme that brings about the synthesis of acetylcholine.

choline esters

choline has some of the activity of a cholineric drug but the effect is multiplied many times over by combining it with an acid, e.g. acetic acid, to form an ester, e.g. acetylcholine. Other choline esters with important pharmacological activity are carbachol, bethanechol, methacholine.

choline nutritional deficiency

requirements for choline are largely dependent on the amount of methionine in the diet. In dogs and cats, under normal circumstances, deficiency is unlikely, but choline is a dietary essential for pigs and young calves. Incoordination, weakness, dyspnea and hock swelling occur in experimental deficiency, but there is little evidence of naturally occurring disease. Poultry fed diets deficient in choline develop perosis.
