Ketoisovaleric acid is an abnormal metabolite originated from the incomplete breakdown of branched-chain amino acids. Chronically high levels of ketoisovaleric acid are associated with maple syrup urine disease (MSUD). MSUD is an inherited metabolic disorder caused by deficiency of branched-chain α-keto acid dehydrogenase complex activity which leads to accumulation of the branched-chain α-keto acids including α-ketoisocaproic acid, α-ketoisovaleric acid and α-keto-β-methylvaleric acid, as well as their respective amino acids in blood and urine. From a chemistry perspective, ketoisovaleric acid is a keto acid, which is a subclass of organic acids. Abnormally high levels of organic acids in blood (organic acidemia), urine (organic aciduria), the brain, as well as other tissues result in general metabolic acidosis.
