CAS 3226-65-1: Methionine sulfoxide

Description:Methionine sulfoxide is a sulfoxide derivative of the amino acid methionine, characterized by the presence of a sulfoxide functional group (–S(=O)–) attached to the sulfur atom of the methionine side chain. It is a chiral compound, existing in two enantiomeric forms, which can have different biological activities. Methionine sulfoxide is often formed as a result of oxidative stress, where reactive oxygen species oxidize methionine residues in proteins. This modification can affect protein function and is implicated in various biological processes, including aging and cellular signaling. The compound is soluble in water and polar organic solvents, making it suitable for various biochemical applications. Methionine sulfoxide can also be reduced back to methionine by specific enzymes, highlighting its role in redox biology. Its CAS number, 3226-65-1, is used for identification in chemical databases and regulatory contexts. Overall, methionine sulfoxide serves as an important biomarker for oxidative damage and is of interest in studies related to oxidative stress and protein chemistry.
