Citrate interference with the determination of acetylcarnitine: a method for its elimination.
Citrate can interfere with the determination of acetylcarnitine when measured by a radioisotopic method. In this report we present a modified procedure designed to avoid this effect. Recovery of added acetylcarnitine was approximately 95%. Acetylcarnitine in normal human plasma was found to range from 0.8 to 19.9 nmol/ml with a mean of 6.3; that of human skeletal muscle ranged from 0.1 to 1.6 nmol/mg protein with a mean of 1.08. The results confirm that exercise gives rise to increased acetylcarnitine content of plasma.
