產品描述

Ademetionine 1,4-Butanedisulfonate(SAMe) is derived from the amino acid methionine and is one of the most important methyl donors in the central nervous system. Methylation (donation of methyl groups) is an essential process in ensuring the proper function of a number of organ systems. SAMe is involved in numerous biochemical reactions in tissue including the liver, joints and brain.

應用

1.Ademetionine 1,4-Butanedisulfonate(SAMe) is a coenzyme involved in methyl group transfers. It is made from adenosine triphosphate (ATP) and methionine by methionine adenosyltransferase (EC 2.5.1.6). Transmethylation, transsulfuration, and aminopropylation are the metabolic pathways that use SAMe. Although these anabolic reactions occur throughout the body, most SAMe is produced and consumed in the liver.

2.Ademetionine 1,4-Butanedisulfonate attached to the methionine sulfur atom in SAMe is chemically reactive. This allows donation of this group to an acceptor substrate in transmethylation reactions. More than 40 metabolic reactions involve the transfer of a methyl group from SAMe to various substrates such as nucleic acids, proteins, and lipids.

3.In bacteria, SAMe is bound by the SAMe riboswitch, which regulates genes involved in methionine or cysteine biosynthesis.
