Usage

General Description

"H-MET-MET-OH" represents a dipeptide comprised of two methionine amino acids. Methionine is an essential amino acid in the body; this means that it must be obtained from the diet because the body cannot produce it. It plays several vital roles in the body, including protein synthesis, the production of the antioxidant molecule glutathione, and as a key component in the methylation process, which is crucial for DNA replication and repair. The chemical structure of this dipeptide indicates that it has an amine group (H-) at one end, a carboxyl group (-OH) at the other end, and two methionine amino acids (-MET-MET-) in between.

Effect of high hydrostatic pressure on prebiotic peptide synthesis

Prebiotic peptide synthesis is a central issue concerning life's origins. Many studies considered that life might come from Hadean deep-sea environment, that is, under high hydrostatic pressure conditions. However, the properties of prebiotic peptide formation under high hydrostatic pressure conditions have seldom been mentioned. Here we report that the yields of dipeptides increase with raised pressures. Significantly, effect of pressure on the formation of dipeptide was obvious at relatively low temperature. Considering that the deep sea is of high hydrostatic pressure, the pressure may serve as one of the key factors in prebiotic peptide synthesis in the Hadean deep-sea environment. The high hydrostatic pressure should be considered as one of the significant factors in studying the origin of life.
