Isobutyryl-L-carnitine is a product of the acyl-CoA dehydrogenases (ACADs), which are a group of mitochondrial enzymes involved in the metabolism of fatty acids or branched-chain amino acids.

We describe on a 3-year-old child referred for evaluation and therapy of a cerebral vascular accident with residual hemiplegia and partial epilepsy. Metabolic investigations initially showed normal urinary organic acids as well as normal blood and urinary amino acids. Blood
A large quantity of propionylcarnitine in the urine of patients with propionic acidemia and methylmalonic aciduria was demonstrated. The amount excreted depended on the administered L-carnitine dose from 25 to 75 mg/kg/day. A high level of propionylcarnitine was also detected
When washed human sperm were incubated in a modified Krebs-Ringer buffer solution in the absence of exogenous metabolizable substrates at 30 degrees C they maintained progressive motility for at least six hours. Under these conditions the spermatozoa apparently utilize endogenous

An immobilized enzyme reactor, made up acylcarnitine hydrolase, carnitine dehydrogenase and diaphorase in sequence, was developed for the sensitive and selective determination of urinary free and individual acylcarnitines by a reversed-phase high-performance liquid chromatography. A 100-microliter urine sample was directly
Tandem mass spectrometry was adopted for newborn screening by North Carolina in April 1999. Since then, three infants with short-chain acyl-CoA dehydrogenase (SCAD) and one with isobutyryl-CoA dehydrogenase deficiency were detected on the basis of elevated butyrylcarnitine/isobutyrylcarnitine (C4-carnitine) concentrations in
