Turnover Rate of Muscle Protein measured by Constant Intravenous Infusion of 14C-Glycine

Abstract

ISOTOPIC methods can be used in two ways for studying the turnover rates of tissue proteins in the living animal: either the rate of catabolism may be measured from the rate of breakdown of labelled protein, or the rate of synthesis from the rate of uptake of label into unlabelled protein. In the steady state the two rates will, of course, be equal. Calculation of the catabolic rate from the decay curve of a labelled protein is valid only if there is no recycling of the label; a condition which, with certain exceptions, is not met in experiments with labelled amino-acids.
