Acetylcholine synthesis and metabolism. Choline is a vitamin like essential nutrient and a methyl donor involved in many physiological processes including normal metabolism and transport of lipids methylation reactions and neurotransmitter synthesis.

Oxidation of choline to glycine betaine is a major pathway for choline degradation and glycine betaine biosynthesis.
Choline biosynthesis. Choline is an organic water soluble compound. In fact this nutrient affects a number of vital bodily functions. When hepatic pc biosynthesis is impaired by either cholinemethionine deficiency or by the absence of specific pc biosynthetic enzymes pemt or cta plasma levels of vldls and hdls are reduced.
However it is often grouped with the vitamin b complex due to its similar properties and functions. In addition to its synthesis in the liver. It is classified as neither a vitamin nor a mineral.
Although this oxidative process is found in all domains of life enzymes involved in the reduction of glycine betaine to choline have not been found. In the nervous system this enzyme is thought to exist primarily in the nerve terminal cytoplasm. Coenzyme a is synthesized in mitochondria and accesses choline acetyltransferase following transport across the mitochondrial membrane into the cytoplasm.
Choline metabolism and malignant transformation. This hypolipidemia is the result of reduced particle secretion by the liver combined with enhanced uptake of mature lipoproteins from the circulation. Choline is also oxidized in the mitochondria to betaine.
The methyl groups of betaine are used to re synthesize methionine from homocysteine thereby providing methionine for protein synthesis and transmethylation reactions. Jump to navigation jump to search. This article needs more medical references for.
