Anti-obesity effects of chondroitin sulfate oligosaccharides from the skate Raja pulchra

We aimed to investigate the anti-obesity effects of chondroitin sulfate (CS) oligosaccharides obtained from cartilage of the skate Raja pulchra and to compare them with those of CSs of other molecular weights (MWts) (skate CS polysaccharides) and origins (shark CS, bovine CS). CSs suppressed pancreatic lipase activity as well as proliferation and lipid accumulation in mature adipocytes. Higher MWt CS had a greater lipase inhibitory activity than...
