– Taurine levels have been determined in primary and secondary subcellular fractions of ox retina and pigment epithelium. About the 79.5% of recovered taurine is located in the soluble fraction (S 3 ), while the remainder is associated with the particulate components. In the secondary subcellular fractions, taurine is primarily associated with the synaptosomal fraction. Cysteine sulphinate decarboxylase is predominantly associated with particulate components of retinal cells. About the 50% of the recovered enzyme activity of crude mitochondria is present in the synaptosomal fraction.
