the intracellular glycosaminoglycans are mainly in the process of degradation , as indicated by their low molecular weight and by their half-life of 7 h , but intracellular dermatan sulfate is degraded more rapidly ( half-life 4-5 h ) than intracellular chondroitin sulfate and heparan sulfate ( half-life 7-8 h ) .
