褐藻寡糖是褐藻胶的寡聚物,是一种功能性寡糖。褐藻寡糖由β-D甘露糖醛酸(ManA)和其C-5差向异构体α-L古洛糖醛酸(GulA)通过1-4糖苷键连接而成。褐藻寡糖分子量低,不仅水溶性强,稳定性高,而且具有很多生物活性,如抗肿瘤、抗氧化、抑菌、促生长等,在药物研制、功能食品开发、绿色农业等领域具有广阔的开发前景。

Alginate oligosaccharide,which is an oligomer of alginate,consisting of β-D-mannuronic acid and its C5-epimer α-L-guluronic acid linked via 1,4-glycosidic bonds,is a kind of functional oligosaccharide.Besides low molecular weight,strong solubility and high stability,alginate oligosaccharide has kinds of biological activities,such as antitumor,anti-oxidation,bacteriostasis and growth promotion,making it potential in pharmaceutical industry,functional foods development and green agriculture.
