An apparatus has been designed to investigate the rate of yellowing of proteins on exposure to ultraviolet radiation. Amino acids were exposed in solution, the rate of yellowing was measured and the decomposition products were investigated. Various protein fractions from wool have been similarly investigated, and conclusions have been drawn about the causes of yellowing. The pH of the solution has a considerable effect on the rate of yellowing. Peptide hydrolysis occurs on exposure.
