SAM is widely used in biochemical research as a methyl group donor in various enzymatic reactions, particularly in the study of methylation processes in DNA, RNA, and proteins. It plays a critical role in understanding epigenetic regulation and gene expression. In the pharmaceutical industry, SAM is utilized in the development of drugs targeting liver diseases, depression, and osteoarthritis due to its role in cellular metabolism and inflammation modulation.
