Study On The Extraction And Properties Of Fish Skin Collagen
Keywords
Abstract
Abstract Collagen was extracted from fish skin using acetic acid and pepsin, and its physical and chemical properties were studied. The results showed that the extracted collagen belongs to typical type I collagen, and its triple helix molecular composition It is [¦Á1(¢ñ)]2¦Á2(¢ñ). The analysis of amino acid composition and denaturation temperature shows that the extracted fish skin collagen is much more stable than other fish due to its own subamino acid content. skin collagen, but it is still less stable than most mammalian skin collagen. UV scanning spectrum, Fourier transform infrared spectroscopy and circular dichroism research results prove that the extracted collagen triple helix structure remains intact
