Abstract
Summary
Glucose - cyclo - acetoacetate (G.C.A.), a precursor of ascorbic acid in germinating legumes and which on hydrolysis gives rise to a reducing dienol glucose, is formed during germination from glucose and acetoacetate. Thiamine and pantothenic acid accelerated biosynthesis of GCA and their antivitamins depressed such synthesis. GCA has thus been shown to be an intermediary product towards biosynthesis of ascorbic acid during germination of legumes.
