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.

A quantitative analysis for urinary acylcarnitines in a patient with neonatal multiple acyl-CoA dehydrogenation deficiency is described. This method (liquid chromatography) can quantify twelve acylcarnitines including glutarylcarnitine and 3 isomeric acylcarnitines (butyryl-1, valeryl- and octanoylisomer) in urine. Before and up

The pool of different carnitine derivatives is formed by carnitine, acetylcarnitine, propionylcarnitine and isovalerylcarnitine. Isovalerylcarnitine is a compound performing activities that differ from those of the other carnitine esters. Its activity on proteolytic enzymes and on the calpain system has
