Question 1

What is the Meaning of Methylmalonic Acid?

Accepted Answer

An organic acid that serves as a critical biomarker in clinical diagnostics; its concentration in blood or urine is inversely correlated with functional vitamin B12 (cobalamin) status. Elevated levels of methylmalonic acid (MMA) reliably indicate a tissue-level deficiency of vitamin B12, a cofactor essential for several metabolic pathways. Measuring MMA provides a functional assessment, superior to simply measuring total serum B12.

Question 2

What is the Origin of Methylmalonic Acid?

Accepted Answer

The term is purely chemical, derived from its structure as a derivative of malonic acid with a methyl group substitution. Its clinical utility was established when researchers elucidated the metabolic pathway linking cobalamin deficiency to the accumulation of this specific acid, a discovery central to hematology and neurology.

Question 3

What is the Mechanism of Methylmalonic Acid?

Accepted Answer

Vitamin B12 is required for the enzyme methylmalonyl-CoA mutase, which catalyzes the conversion of methylmalonyl-CoA to succinyl-CoA, an intermediate in the Krebs cycle. When cobalamin is deficient, this conversion is impaired, causing methylmalonyl-CoA to hydrolyze into MMA, which then accumulates systemically. Therefore, measuring MMA provides a direct, functional assessment of B12's role in intermediary metabolism, a process vital for nervous system health and energy production.
