Journal Title: Scholars Academic Journal of Pharmacy - Year 2016, Vol 5, Issue 12
Abstract
Abstract:Studies on amino acid composition and antioxidant activities of collagen Polypeptides from the HolothurianobilisSelenka were carried out in this paper. Results revealed that collagen polypeptides mainly contains glycine(Gly), alanine(Ala), glutamate (Glu), proline (Pro) and hydroxyproline (Hyp) with high medicinal values and good tasting. The rate of delicious amino acid, pharmacodynamics amino acid and essential amino acid in the total collagen polypeptide were accounted for 65.1%, 58.08% and 24.96% with IC50 value of5.78 mg/ml, 4.20mg/ml and 0.27mg/ml in the antioxidant free-radical tests, respectively. Keywords:HolothurianobilisSelenka; collagen polypeptide; amino acid composition; free radicals; antioxidant activity.
