Summary:In an investigation into making more effective use of underutilized fisheries resources, collagen was prepared from Callistoctopus arakawai arm. The arm was only slightly solubilized in acetic acid but on digestion with 10% pepsin, pepsin-solubilized collagen (PSC) was produced as a pinkish fibre. The PSC has a chain composition of alpha1alpha2alpha3 heterotrimer, different from Octopus vulgaris skin. The denaturation temperature of this collagen was lower than porcine collagen. This report indicates that C. arakawai has potential for supplementing the skin of land vertebrates as a source of collagen. (Original abstract - amended)
