Acid-soluble collagen (ASC) from the skin of silver carp (Hypophthalmichthys molitrix) was isolated and some properties of ASC were investigated. SDS-PAGE patterns showed ASC from silver carp skin was type 1 collagen. Sulfopropyl-Toyopearl 650(M) column chromatography indicated that ASC from silver carp skin was composed of three kinds of alpha chains, alpha(1), alpha(2) and alpha(3). Hydroxyproline and proline content of ASC from silver carp skin was 192 residues/1000 residues, which was similar to that of ASC from carp skin. Denaturation temperature (T-d) of ASC from silver carp skin was around 29 degrees C. The results showed that some properties of ASC from silver carp skin were similar to those of ASC from carp skin. However, the peptide map of ASC from silver carp skin digested by pepsin was distinguished with that of ASC from carp skin. (C) 2009 Elsevier Ltd. All rights reserved.
