Abstract

Abstract: Aqueous solutions of simple dipeptides containing about 1% hydrogen peroxide have, been photolyzed at room temperature and the resulting radicals studied by electron spin resonance. The peroxide gives OH which abstracts hydrogen from the peptide. Abstraction of a hydrogen from the carbon adjacent to the peptide nitrogen to give a single radical occurs in the following cases: glycylglycine, P-alanylglycine, L-alanylglycine, P- ...
