Alpha-keto acids in vitamin-free casein hydrolyzates (acid)

Alpha-keto acids in vitamin-free casein hydrolyzates (acid)

P MACLEOD et al. Science. .

Abstract

alpha-Ketoglutaric and pyruvic acids were isolated as their 2-4-dinitrophenylhydrazones from five different commercial samples of vitamin-free acid hydrolyzates of casein. In addition, one sample yielded traces of alpha-ketobutyric acid. The hydrazones were converted by hydrogenation to glutamic acid, alanine, and alpha-aminobutyric acid and identified by paper chromatography.
