| 3-methylcrotonyl-CoA | (CH3)2C==CHCOSCoA;an intermediate in the degradation of l-leucine; accumulates in a deficiency of 3-methylcrotonyl-CoA carboxylase. 3-methylcrotonyl-CoA carboxylase, an enzyme in the pathway of l-leucine degradation that catalyses the reaction of 3-methylcrotonyl-CoA with CO2, ATP, and water to form ADP, orthophosphate, and 3-methylglutaconyl-CoA; a deficiency of this enzyme causes episodes of severe metabolic acidosis.

| 3-methylcrotonyl CoA carboxylase deficiency |
an autosomal recessive aminoacidopathy due to deficiency of methylcrotonoyl-CoA carboxylase, characterized by increased urine levels of 3-methylcrotonylglycine, 3-methylcrotonic acid, and 3-hydroxyisovaleric acid and variable presentation of mental retardation, central nervous system dysfunction, and muscular atrophy. Written also β-methylcrotonyl CoA carboxylase deficiency.

| 3-methylcrotonylglycine |
a conjugate of 3-methylcrotonic acid and glycine, formed and excreted in excess in the urine when 3-methylcrotonoyl-CoA carboxylase activity is impaired.
