Physicochemical characteristics and fibril-forming properties of collagen from paddlefish (Polyodon spathula) and globefish (Fugu flavidus) skin byproducts
Abstract Acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC) from the skin byproducts of paddlefish (ASC-P and PSC-P) and globefish (ASC-G and PSC-G) were purified and characterized. The imino acid contents of ASC-P, PSC-P, ASC-G and PSC-G were 194.1, 197.9, 186.4 and 189.7 residues/1000 r...
