Physicochemical properties and potential beneficial effects of porphyran from Porphyra haitanensis on intestinal epithelial cells

This study examined the beneficial effects of porphyran from Porphyra haitanensis (PHP) on intestinal epithelial cells, in terms of cell proliferation and migration and elucidated the potential molecular mechanism of action of PHP. Purified PHP is a homogenous polysaccharide with a molecular weight of 2.01 × 105 Da, intrinsic viscosity [η] of 463.76 mL/g, and radius of gyration of 61.2 nm. When the intestinal epithelial wound healing activity of...
