Biosynthesis of Vitamin B6: II. Localization of 14C-Carbons in Vitamin B6

14C-Labeled pyridoxal was synthesized from 2-14C-glycerol and 1, 3-14C-glycerol. Radioactivity of 2-14C-glycerol was incorporated in the pyridine moiety of pyridoxal, whereas that of 1, 3-14C-glycerol was incorporated in the pyridine moiety of pyridoxal and CO2. From these results we suggested that...

Zusammenfassung:14C-Labeled pyridoxal was synthesized from 2-14C-glycerol and 1, 3-14C-glycerol. Radioactivity of 2-14C-glycerol was incorporated in the pyridine moiety of pyridoxal, whereas that of 1, 3-14C-glycerol was incorporated in the pyridine moiety of pyridoxal and CO2. From these results we suggested that 5, 6-positions of the carbon atoms of pyridoxal and that in hydroxymethyl attached to 5-C of pyridoxal came from glycerol and other carbons from leucine or its related compounds.
