Description

• Application: L-Methionine has been used as a component of media to culture various cancer cells and to study its effects on the cell cycle.[1] It has also been used as a component of DMEM medium to culture satellite cells from the white muscle of trouts.[2]
• Biochem/physiol Actions: Methionine is an essential amino acid which acts a precursor for transmethylation and transsulphuration. In proteins, L-methionine is the biologically active form.[3] The adenosylation of methionine results in the formation of S-adenosyl-L-methionine (SAM), which serves as a methyl donor to various substances. L-Methionine′s metabolic product glutathione is known to regulate immune response and has antiviral action.[4]
