Abstract
The rate of oxidation of non-hydroxyamino acid by HIO4 with a mixture of 1 ml amino acid (5-10 mg), 1 ml 0.5[image] HIO4, and 20 ml [image]/25 phosphate buffer (pH 8.03) at 60[degree]C for 24 hours in a sealed tube was determined by NH3 evolution. The rate increased in the following order: L-asp, L-dopa, L-leu, L-his, DL-phe, L-try, L-Ileu, L-lys, DL-n-leu, DL-met, L-glu, [alpha]-amino-butyric acid, DL-val, L-ornithine, DL-n-val, L-arg, [alpha]-ala, [beta]-amino-butyric acid, gly, [beta]-ala. N-Methyl derivatives of L-leu, L-lys, DL-n-leu, and DL-n-val showed lower rate than respective non-substituted amino acids. Stoichiometrical production of corresponding aldehydes were confirmed with all amino acids tested.This publication has 2 references indexed in Scilit:
