Biochem/physiol Actions

2-Methylbutyryl-L-carnitine is not usually detected in normal individuals. The elevation of 2-methylbutyrylcarnitine suggests a deficiency of a dehydrogenase specific for isobutyryl-CoA, important in the differential diagnosis of branched chain organic acidurias by analysis of urinary organic acids and acylcarnitines in plasma or dried blood spots.

2-methylbutyryl-CoA dehydrogenase deficiency, also known as short/branched-chain acyl-CoA dehydrogenase (SBCAD) deficiency, is a recently described autosomal recessive disorder of L-isoleucine metabolism. Only 4 affected individuals in 2 families have been described. One patient developed athetoid cerebral palsy, and another had

Isovalerylcarnitine (IVC) a product of the catabolism of L-leucine, is a potent activator of the Ca2+-dependent proteinase (calpain) of human neutrophils. At concentrations of Ca2+ in the low micromolar range, activation was 12 to 15-fold, and the activity exceeded that

Carnitine levels and acylcarnitine profiles in a patient with mild multiple acyl-CoA dehydrogenase deficient beta-oxidation were compared with control results. Whereas blood and urine total carnitine levels were moderately decreased, blood esterified carnitine levels in the patient were about 2-fold

Pediatric research, 18(12), 1325-1328 (1984-12-01)
Concentrations of l-carnitine and acylcarnitines have been determined in urine from patients with disorders of organic acid metabolism associated with an intramitochondrial accumulation of acyl-CoA intermediates. These included propionic acidemia, methylmalonic aciduria, isovaleric acidemia, multicarboxylase deficiency, 3-hydroxy-3-methylglutaric aciduria, methylacetoacetyl-CoA thiolase
