The causes of carnitine deficiency syndromes are not completely understood, but decomposition of L-carnitine in vivo is likely t o be involved. Carnitine is metabolized to y-butyrobetaine, and crotonobetaine is probably an intermediate in this pathway. To validate experimentally the precursor-produc

✦ Synopsis
Abstract
Hexadecylphospho[methyl‐^14^C]‐choline was synthesized in two steps from the tetra‐n‐butyl‐ammonium salt of phosphoryl[methyl‐^14^C]‐choline and 1‐bromohexadecane, and purified by column chromatography on silica gel. The total yield of the radioactive synthesis was 35%, whereas the total yield of the non‐radioactive synthesis was 40%. Hexadecylphospho[methyl‐^14^C]‐choline may serve as a useful tool for pharmacokinetic and biochemical studies of this new antitumor drug.
