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 .
Choline is an essential nutrient, commonly grouped with the B complex vitamins, that plays key roles in many biological processes.
