Concentrations of carnitine, acetyl carnitine, propionyl carnitine, and long chain acyl carnitines have been measured in hepatic tissue of normal and vitamin B-12 deficient rats using radiolabelled butyrobetaine to label carnitine pools. Increased levels of propionyl carnitine were seen in the livers of vitamin B-12 deprived animals when compared to those from normal animals. Methylmalonyl carnitine was not detected in the B-12 deprived animals. Free carnitine levels were no different in the livers from the B-12 deprived animals than from the normal control animals.
