Popis:	Acid-soluble collagen (ASC) was extracted from the skin of walleye pollock ( Theragra chalcogramma ) and partially characterized. It exhibited a maximum absorbance at 220 nm, but little absorbance near to 280 nm. Amino acid composition and SDS-PAGE suggested that the collagen might be classified as type I collagen. Moreover, FTIR investigations showed the existence of helical arrangements of collagen. The denaturation temperature ( T d ) and shrinkage temperature ( T s ) were 24.6 °C and 47 °C, respectively, both lower than those of mammalian collagens. However, T d of walleye pollock skin collagen was higher than that of cod skin collagen reported previously. These results indicate that walleye pollock skin is a potential source of collagen and provide the theoretical basis for further research.
