| 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. |
