Experts identify a novel fucosylated heparan sulfate from the midgut gland of the Japanese scallop

Glycosaminoglycans (GAGs), including chondroitin sulfate (CS), heparan sulfate (HS), heparin, and hyaluronan are linear and acidic polysaccharides found in the extracellular matrix of all animal tissues. GAGs are widely used as functional ingredients in health products, pharmaceuticals, and cosmetics, and are prepared from biological samples such as shark cartilage and porcine intestinal mucosa. Consequently, the demand for new sources of GAGs is ever-present. For example, the supply source of the anticoagulant heparin-;generally prepared from porcine intestinal mucosa in China-;was threatened by African swine fever in 2018.
