title: A technique for measurement of methylmalonic acid in cattle urine.
abstract: Methylmalonic acid was measured in cattle urine by decarboxylating it to propionate with sulfuric acid and heat and quantifying the propionate so formed by gas-liquid chromatography. Crystalline methylmalonic acid added to cow urine was recovered quantitatively.
