Amino Acid Metabolism - the Methionine (SAM) Cycle (2)

The video explains the Sam Cycle, also known as the Methionine Cycle, highlighting the role of methionine in generating S-Adenosyl Methionine (SAM), a crucial methyl donor for biosynthetic reactions and DNA methylation. It details the conversion of methionine to SAM and the subsequent transformation of homocysteine back to methionine, emphasizing the importance of cofactors like folate and vitamin B12. The video also discusses the consequences of deficiencies in these vitamins, such as elevated homocysteine levels linked to cardiovascular diseases.
