Abstract

Abstract— Glycolipid analysis of chicken retina and brain indicated the presence of cerebroside, cerebroside 3‐sulphate and sulphogalactosylglycerolipid In retina, the ratio of cerebroside to cerebroside 3‐sulphate was approximately half compared to brain. During chicken retina ontogenesis the ratio of cerebroside 3‐sulphate to sulphogalactosylglycerolipid increased rapidly and in the adult animal, the amount of cerebroside 3‐sulphate was 14 times higher than that of sulphogalactosylglycerolipid. The activity of PAPS: cerebroside sulphotransferase and arylsulphatase A in developing chicken retina indicated that the general ontogenic profiles of retinal PAPS: cerebroside sulphotransferase and arylsulphatase A were similar to those obtained for the brain. Both the enzymes showed the highest activity just before hatching. The significance of occurrence of sulpholipids in retina is discussed.
