Photochemical reactions of free and N-acetyl alpha-amino acids with chlorine and deuterium labeled hydrogen peroxide have been used to determine both the relative rates of reaction of molecules of these classes and the relative reactivity of their different types of hydrogen toward abstraction by chlorine and oxygen centered radicals. The relative rates of reaction of these species range over more than 3 orders

Preparations of the enzyme isopenicillin N synthetase from Cephalosporium acremonium convert the modifiedsubstrate (L-α-amino-δ-adipyl)-L-cysteinyl-D-(α-aminobutyrate) into both penam and cepham products, which have been isolated and their structures established.
