Utilization of the D-Isomers of Arginine and Histidine by Chicks and Rats

Abstract

Young chicks and rats were fed crystalline amino acid diets deficient in either arginine or histidine, and the growth - promoting capacity of the D - isomers of these two amino acids was examined. D-arginine had no growth -promoting activity in either chicks or rats. D-histidine had minimal growth-promoting activity (about 20%) in chicks and no bio-activity in rats. Copyright © 1981.
