Metabolic incorporation of L-valine-[14C] into S-(2-carboxypropyl)glutathione and S-(2-carboxypropyl)cysteine in garlic

Abstract

It was proved that uniformly labeled L-valine-[14C] is incorporated into 2-carboxypropyl group of S-(2-carboxypropyl)glutathione and S-(2-carboxypropyl)cysteine in excised root of garlic. It was also found that leucine is formed from valine in a similar fashion as reported in various microorganisms. The biosynthetic pathway of these compounds from valine in garlic is discussed. © 1962, The Pharmaceutical Society of Japan. All rights reserved.
