The activated methyl cycle
WebS-adenosyl methionine (SAM) is formed in the activated methyl cycle by transfer of the adenosyl group from adenosine triphosphate to the sulfur of methionine (see Fig. 12-10). The methyl group attached to the methionine sulfur transfers readily to the nitrogen, oxygen, or carbon of an acceptor. WebIn the chemical sciences, methylation denotes the addition of a methyl group on a substrate, or the substitution of an atom (or group) by a methyl group.Methylation is a form of alkylation, with a methyl group replacing a hydrogen atom. These terms are commonly used in chemistry, biochemistry, soil science, and the biological sciences.. In biological …
