Radiolysis of Aqueous Solutions of Glycine

A detailed mechanism for the radiolysis of the glycine-water system is developed. The treatment is based on the various literature sources and on new experimental findings which are described. It is proposed that the indirect action of radiation on glycine in oxygenfree solution results in formation of the free-radical intermediates CH/sub 2/COOH and NH/sub 2/CHCCOH. Although most of these ultimately yield acetic acid and glyoxylic acid, respectively, it is concluded that some undergo radical-radical reaction to yield succinic acid, aspartic acid, and diaminosuccinic acid. Effects of oxygen, glycine concentration, and pH are discussed. (auth)
