Influence of marine oligosaccharides on the response of various biological systems to UV irradiation.

摘要

Low molecular weight alginate-derived oligosaccharide (ADO) (373-571Da) and chito-oligosaccharide (COS) (855-1671Da) were purified from alginate and chitosan, and known as marine oligosaccharides with polyanionic and polycationic properties, respectively. We compared the effects of ADO and COS on cell regulation using several biological models (Candida albicans, Escherichia coli and Bacillus subtilis spore), cellular uptake determination, erythrocytes haemolysis inhibition and antioxidant capacity assay to investigate stress response under UV radiation. Our results further confirmed the anti-UVR potential of ADO and COS and their potential for commercial UVR protector application in the area of functional foods as food ingredients
