WebCarnitine can increase the availability of nonesterified CoA for these other metabolic pathways (6). Within the mitochondrial matrix, CAT (carnitine acetyl transferase) catalyzes the transesterification of short- and medium-chain fatty acids from CoA to carnitine ( … WebThe serum acylcarnitine profile is usually normal in CPT I deficiency, but acylcarnitine levels are low. CPT II and translocase deficiency can be identified but not distinguished from each other by biochemical testing, both showing elevated C16 esters. The acylcarnitine profile may be normal in milder disease.
