Biochem/physiol Actions

3-Hydroxyisovaleryl-L-carnitine is an endogenous metabolite that can result from impairment in the leucine catabolic pathway. 3-Hydroxyisovaleryl-L-carnitine was observed in plasma and urine of patient with isolated 3-methylcrotonyl-CoA carboxylase deficiency and is used as biomarker of biotin deficiency in humans and other metabolic disorders.
