DL-甲硫氨酸 [DL-蛋氨酸]，DL-Methionine；≥99.0% (NT)

DL-Methionine has been used to study the susceptibility of methionine to oxidation during the development of monoclonal antibodies.[1]

 

Methionine is an essential amino acid which acts a precursor for transmethylation and transsulfuration. In proteins, L-methionine is the biologically active form. D-methionine is converted to L-methionine by enzymes in the body.[2] 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.[3]
