Common Name | 2-Hydroxy-3-methylbutyric acid |
---|
Description | 2-Hydroxy-3-methylbutyric acid (also known as 2-hydroxyisovaleric acid) is a metabolite found in the urine of patients with phenylketonuria (PMID: 7978272 ), methylmalonic acidemia, propionic acidemia, 3-ketothiolase deficiency, isovaleric acidemia, 3-methylcrotonylglycemia, 3-hydroxy-3-methylglutaric acidemia, multiple carboxylase deficiency, glutaric aciduria, ornithine transcarbamylase deficiency, glyceroluria, tyrosinemia type I, galactosemia, and maple syrup urine disease (PMID: 11048741 ). 2-Hydroxyisovaleric acid has also been identified in the urine of patients with lactic acidosis and ketoacidosis (PMID: 884872 ), and in the urine of severely asphyxiated babies (PMID: 1610944 ). 2-Hydroxyisovaleric acid originates mainly from ketogenesis and from the metabolism of valine, leucine, and isoleucine (PMID: 6434570 ). 2-Hydroxy-3-methylbutyric acid has been identified in the human placenta (PMID: 32033212 ). |
