Methylcitric acid (MCA) is elevated in body fluids of patients with propionic acidaemia (PA; OMIM 232000, 232050), methylmalonic aciduria (MMA; OMIM 251000, 251120) and multiple carboxylase deficiency (OMIM 253260, 253270), which are inherited disorders. MCA is formed by condensation of accumulated propionyl- CoA and oxalacetate by the enzyme si-citrate synthase (EC 4.1.3.7). MCA molecule has two stereogenic centers so that it can occur in the form of four stereoisomers. Only two stereoisomers of MCA, (2S, 3S) and (2R, 3S), were found in human urine (PMID: 17295121).

(PMID: 17295121) [HMDB] 2-Methylcitric acid (Methylcitric acid) is an endogenous metabolite in the 2-methylcitric acid cycle. 2-Methylcitric acid accumulates in methylmalonic and propionic acidemias and acts as a marker metabolite. 2-Methylcitric acid markedly inhibits ADP-stimulated and uncoupled respiration in mitochondria supported by glutamate[1]. 2-Methylcitric acid (Methylcitric acid) is an endogenous metabolite in the 2-methylcitric acid cycle. 2-Methylcitric acid accumulates in methylmalonic and propionic acidemias and acts as a marker metabolite. 2-Methylcitric acid markedly inhibits ADP-stimulated and uncoupled respiration in mitochondria supported by glutamate[1]. 2-Methylcitric acid (Methylcitric acid) is an endogenous metabolite in the 2-methylcitric acid cycle. 2-Methylcitric acid accumulates in methylmalonic and propionic acidemias and acts as a marker metabolite. 2-Methylcitric acid markedly inhibits ADP-stimulated and uncoupled respiration in mitochondria supported by glutamate[1].
