摘要：

Acid soluble collagen (ASC) and pepsin soluble collagen (PSC) were isolated from rohu skin with the yield of 64.2 and 6.8% (dry weight basis), respectively. Both collagens had glycine as the major amino acid with imino acid content of 196-202 residues/1,000 residues and were characterized as type I collagen with molecular composition of (1)(2)2-heterotrimer. Fourier transform infrared spectra of both collagens were similar, with no shift in wavenumber of all amide bands. The T-max value of ASC and PSC was 36.40 and 35.48 degrees C, respectively. The zero surface net charge of ASC and PSC was found at pH 5.9 and 5.3, respectively.
