The relative importance of three different routes for the N-nitrosation of amino acids (nitrosation by N 2 O 3 , by and by intramolecular migration of the nitroso group from the initially nitrosated carboxylate group) was investigated for methylaminobutyric acid, methylaminoisobutyric acid, azetidin
The kinetic study of the permanganic oxidation of some amino acids (glycine, L-alanine, L-Ο°-amino-n-butyric acid, L-norvaline, and L-norleucine) has been carried out in buffered acid medium at 1 Ο½ pH Ο½ 3 using a spectrophotometric technique. An autocatalytic effect due to Mn 2Ο© ions was found in all
The free amino acids of the liver and muscle of C. punctatus exposed to 1 pprn of copper solphate solution up to 84 days were investigated. Few amino acids, notably cystine and tryptophan, disappeared and fen new amino acids appeared. These changes in the free amino acids may be due to toxic effects
