A modification of the method of hydroxyproline determination in proteins was devised. The modification consists of the hydrolysis of proteins in 72% perchloric acid of 100Β°C for 2 hr instead of 20 hr, autoclaving in 6 N HCl or 2 N Ba(OH)\*. Determination of hydroxyproline by the modified method does
Methionine is present in small amounts in proteins, and methods for its determination usually involve acid hydrolysis of the protein and subsequent amino acid analysis (1) although there are a number of colorimetric methods available (2). However, methionine sulfur is easily oxidized, and it is poss
