Publikováno v: The Journal of Nutrition. 133:1362-1367

Pyridoxine-5'-beta-D-glucoside (PNG), a glycosylated form of dietary vitamin B-6, is partially hydrolyzed in the small intestine by the cytosolic enzyme pyridoxine-5'-beta-D-glucoside hydrolase (PNG hydrolase) and by the brush border enzyme lactase p

Autor: Qiuyan Chen, Nan Qian Li, A. Catharine Ross, Christopher J. Cifelli, Reza Zolfaghari, Siam O. Lieu

Retinoic acid (RA), a principal metabolite of vitamin A (retinol), is an essential endogenous regulator of gene transcription and an important therapeutic agent. The catabolism of RA must be well regulated to maintain physiological concentrations of
