The Excretion of Methylmalonic and Formiminoglutamic Acids During the Induction and Remission of Vitamin B12 Deficiency in Sheep

Abstract

The excretion of methylmalonic acid (MMA) in the urine of severely vitamin Bn-deficient sheep was 5-12 times greater, and that of formiminoglutamic acid (FIGLU) was more than 30 times greater, than that of pair-fed, vitamin B12-injected controls.
