Vitamin E Deficiency and Biosynthesis of Glycine,Serine,and Methionine in Rabbits. ∗

Abstract

Summary

Injections of sodium formate-C¹⁴ resulted in no activity in the methionine from the protein of skeletal muscle from normal rabbits but such activity did appear in the methionine of vit. E-deficient rabbits. The specific activities of glycine and serine were essentially the same in normal and in deficient skeletal muscle protein following injections of glycine- 1-C¹⁴. In spite of this the activity of the protein from deficient rabbits was much higher than that of the normal controls.
