Abstract
In the previous communication the authors observed that L-Na-glutamate, L-glutamic acid, and L-aspartic acid strikingly inhibited the autoxidation of L-ascorbic acid.
In this report the effect of some other amino acids or α-keto acids upon the autoxidation of that vitamin was studied arid the following results were obtained:-
L-ascorbic acid coexisting with those amino acids or α-keto acids such as L-cysteine, Lglutamic acid, L-Na-glutamate, L-aspartic acid L-methionine, DL-tryptphane, α-keto glutaric acid, oxalacetic acid, and pyruvic acid seemed to be very strikingly protected from the autoxidation; but DL-alanine, DL-serine, L-valine, glycine, L-arginine, L-lysine, and Lproline had no such effect.
