L-Methionyl-D-methionine

Description:
L-Methionyl-D-methionine, identified by the CAS number 89680-18-2, is a dipeptide composed of two methionine amino acids, one in the L-form and the other in the D-form. This compound is notable for its role in various biochemical processes, particularly in protein synthesis and metabolism. Methionine is an essential amino acid, meaning it must be obtained through diet, and it plays a critical role in methylation reactions as a precursor to S-adenosylmethionine (SAMe). The presence of both L and D forms in this dipeptide can influence its biological activity and stability, as the D-amino acid is less common in natural proteins. L-Methionyl-D-methionine may exhibit unique properties compared to its individual components, including altered solubility and potential effects on cellular processes. Its applications may extend to nutritional supplements, pharmaceuticals, and research in peptide synthesis. However, specific characteristics such as solubility, melting point, and reactivity would require empirical data for precise evaluation.
