Abstract: (6526 Views)
The natural and bioactive compounds from marine animals can be used as functional compositions for healthcare. Collagen and gelatin of marine animals could be having pharmacological and cosmetic applications. In the present study collagen was extracted from the body wall of sea cucumber (S.horrens) collected from Chahbahar Bay and its Amino acid composition was investigated. Also, gelatin from this collagen was extracted according to acidic hydrolyzed method and the functional properties were studied. The type of purified collagen was identified by the SDS-PAGE method. The results indicated the extracted collagen was the type I, because it had a α1 chain by the molecular weight of 125 KDa and a heavy band of β chain with the molecular weight of 250 KDa. The collagen contained high amount of Imino Acids and the glycine was the dominant Amino acid. The melting and gelling point of the Gelatin was 300C and 50C, respectively. The viscosity of the gelatin was 2.065 cp, lower than other fish species and mammals.
