A SIMPLE KEY FOR PEPTIDES FOR SKIN UNVEILED

These bonds type involving the alpha carboxyl of one residue and also the alpha amine of One more. The smallest entities in just this group are 2,5-diketopiperazines, derived from the cyclization of the dipeptide.From the displacement action (a classical SN2 reaction), an amine displaces the halide to form the N-substituted glycine residue. The sub
