Question
Deficiencies of carnitine, carnitine acyltransferases, or carnitine/acylcarnitine translocase affect the metabolism of long-chain
fatty acids. Many of the symptoms are similar, and include hypoketotic hypoglycemia, low ketone levels and low blood sugar
with fasting, and damage to the liver, heart, or muscles due to fatty acid buildup in those tissues. Symptom severity varies with
the form of the deficiency.
The following abbreviations are used: carnitine acyltransferase (carnitine palmitoyltransferase), CPT and carnitine/acylcarnitine
translocase, CACT.
Identify each symptom or effect as a deficiency of CPT I, CPT II, or CACT.
CPT I deficiency
CPT II deficiency
CACT deficiency
Answer Bank
acyl carnitine not transported into mitochondrial matrix
long-chain fatty acids not transferred to carnitine
long-chain fatty acids remain attached to carnitine in matrix
