The ceroid lipofuscinoses are inherited lysosomal diseases of children characterized by a fluorescent lipopigment stored in a variety of tissues. Defects in lipid metabolism or the control of lipid peroxidation have been postulated to explain their pathogenesis. In the present study, lipopigment was isolated from the liver of sheep affected with ceroid lipofuscinosis. It was 70% protein, the rest being mainly lipids. These were only one-sixth as fluorescent as total liver lipids, but contained a number of fluorophors. None were major components of the lipopigment or the postulated fluorescent product of lipid peroxidation. Lipopigment lipids included the lysosomal marker bis(monoacylglycero)phosphate that contained 42.9% linoleate and 16.5% linolenate. Lipopigment neutral lipids were dolichol, dolichyl esters, ubiquinone, free fatty acids, and cholesterol, indicative of a lysosomal origin of the lipopigment. Phosphatidylcholine, phosphatidylinositol, phosphatidylserine, and phosphatidylethanolamine were present in proportions and with fatty acid profiles typical of lysosomes. No differences were found between the lipids of total control and affected livers, nor the fatty acid profiles of their phosphatidylcholine, phosphatidylethanolamine, or triglycerides. It is concluded that ovine ceroid lipofuscinosis is not a lipidosis, nor does the lipopigment arise from the abnormal peroxidation of lipids. Strong similarities between the lipopigment and the age pigment lipofuscin were noted.
