2-Methylpropanedioic acid C화학적 특성, 용도, 생산
화학적 성질
white crystalline powder용도
2-Methylpropanedioic acid binds with coenzyme A to form methylmalonyl-CoA, also a metabolic intermediate transformed to succinic acid (SA) by a vitamin B12-dependent catalytic step, and is broadly used as a clinical biomarker of functional vitamin B12 status.정의
ChEBI: A dicarboxylic acid that is malonic acid in which one of the methylene hydrogens is substituted by a methyl group.Biological Functions
Methylmalonic acid is capable of diffusing out of cells in which it is being produced, so it may be detected in excess in the blood, CSF, and urine of patients with these various forms of the disease.일반 설명
Methylmalonic acid is an indicator of vitamin B12 deficiency and methylmalonic acidemia. This Certified Spiking Solution? is suitable for use in preparation of calibrators or controls in clinical and diagnostic testing using GC/MS or LC/MS.Purification Methods
The acid crystallises as the hydrate from water. [Beilstein 2 IV 1932.]2-Methylpropanedioic acid 준비 용품 및 원자재
