Choline chlorure
Choline chloride is used as a substrate for choline acetyl transferase.
Choline chloride is an organic compound and a quaternary ammonium salt . It is a weak acid. Choline chloride is the salt of the naturally occurring choline, the pre-stage of the neurotransmitter acetylcholine, which is important for mnemonic and thought-processes. Choline occurs naturally in fungi, hop and kingcups and as integral part of lecithin. Choline chloride is a common food additive in animal husbandry.
Biochem/physiol Actions: The enzymatic activities of butyrylcholinesterase (BChE) and paraoxonase 1 (PON1), two serum enzymes synthesized by the liver and related with inflammation, were decreased in a sepsis animal model injected with LPS. Choline chloride administered intravenously at 20 mg/kg body weight prevents the LPS-mediated decreases in the activities of these two enzymes.
