Radiolytic Oxidation of Two Inverse Dipeptides, Methionine-Valine and Valine-Methionine: A Joint Experimental and Computational Study
Autor: Jean-Louis Marignier, Pierre Archirel, Chantal Houée-Levin
Publikováno v: The journal of physical chemistry. B. 123(43)
The two inverse peptides methionine-valine (Met-Val) and valine-methionine (Val-Met) are investigated in an oxidative radiolysis process in water. The OH radical yields products with very different absorption spectra and concentration effects: Met-Va
