Contribution of rat liver and gastrointestinal tract to whole-body protein synthesis in the rat

Abstract

The rate of protein synthesis was assessed in liver, stomach, small and large intestine and in the whole body of rats by injection of 100 mumol of [14C]leucine/100 g body wt. In each of the tissues turnover was very rapid, so that taken together they accounted for 43% of the protein synthesized by the whole animal.
