SAM Cycle (S-Adenosylmethionine Cycle)

The video tutorial discusses the critical role of methylation in biochemistry, focusing on S-adenosyl methionine (SAM) as a methyl group donor. It explains the mechanisms of methylation reactions, including the role of various enzymes like methyltransferases. The tutorial also covers the regeneration of methionine from homocysteine and the methionine synthesis pathway, highlighting the importance of these processes in cellular functions.
