Abstract
We compared the sphingolipid content of urine from a patient with Farber's disease with that of control urine. The ceramides were measured by high-performance liquid chromatography. The patient's urine contained 1.2 mug of ceramides per milligram of creatinine, more than 200-fold the normal amount. The urinary ceramides were isolated by high-performance liquid chromatography for further identification. They contained mainly nonhydroxy fatty acids and only a small quantity of those with 2-hydroxy fatty acids. This contrasts with the previously described composition of the patient's renal and cerebellar tissue. The fatty acid and long-chain base compositions of the urinary ceramides containing nonhydroxy fatty acids were nearly identical to those of the patient's kidney.This publication has 0 references indexed in Scilit:
