酵母－β－葡聚糖 dextran ，glucan又称右旋糖酐。为一种多

-Β- yeast glucan dextran, glucan, also known as dextran. It is a polysaccharide. Certain microorganisms present in secreted mucus in the growth process, modern study found that the most abundant polysaccharide B-glucan contained in Agaricus and have higher biological activity. Dextran having a higher molecular weight, primarily in the D- glucopyranosyl α, 1 → 6 bond, a branched point have 1 → 2,1 → 3,1 → 4 linked, and are β-1, 3 / -1,6 highest biological activity of β- glucan binding. With microbial species and different growth conditions, structure and function, there are differences

酵母－β－葡聚糖 dextran ，glucan又称右旋糖酐。为一种多糖。存在于某些微生物在生长过程中分泌的粘液中，现代研究发现，姬松茸中含有的B葡聚多糖最为丰富且具有较高的生物活性。葡聚糖具有较高的分子量，主要由D－葡萄吡喃糖以α，1→6键连接，支链点有1→2、1→3、1→4连接的，并且以β-1,3/-1,6结合的β-葡聚糖生物活性最高。随着微生物种类和生长条件的不同，其结构与功能也有差别

Dextran and dextran are also called dextran. It's a polysaccharide. It exists in the mucus secreted by some microorganisms during the growth process. Modern research has found that Agaricus blazei Murrill contains the most abundant b-Glucan with high biological activity. Dextran has a high molecular weight, which is mainly linked by D-glucopyranose with α, 1 → 6 bonds, with 1 → 2, 1 → 3, 1 → 4 links at the branch points, and β - glucan with β - 1,3 / - 1,6 has the highest biological activity. The structure and function of microorganism are different with the variety and growth condition of microorganism
