Ademetionine is a common co-substrate involved in methyl group transfers to nucleic acids, proteins and lipids. It is produced from ATP in the liver and methionine, by action of the enzyme methionine adenosyltransferase. Ademetionine is an important intermediate in the biosynthesis of many molecules, including amino acids, hormones, and neurotransmitters. It is essential for the metabolism of sulfur-containing compounds and is involved in the methylation of DNA. Ademetionine may act to affect a variety of biochemical and physiological processes, including the regulation of gene expression, epigenetic modifications, and the modulation of cell proliferation, differentiation, and apoptosis. It also possesses anti-inflammatory, antioxidant, and anti-cancer effects.
