Glutamine and Glutamic Acid as Sources of Supplemental Nitrogen for Adult Rats

Abstract

Summary

The utilization of α- and amide nitrogen as sources of supplemental nitrogen to reduce nitrogen losses in the adult rat was studied using the nitrogen balance technique. Although young rats have been shown to utilize amide less efficiently than α-amino nitrogen as a source of supplemental nitrogen for carcass nitrogen gains, adult rats utilized the two equally well. Level of calorie intake or nutritional state of the adult animals did not influence the results.
