描述

产品介绍 25℃100ml水能溶23.2。比旋光度[α]D +177.4°。环糊精是呈环状的低聚葡萄糖。通常是由6个、7个或8个葡萄糖单元通过α,1-→4键环状相至连接的结晶体。分别称α-、β或γ-环糊精。
别名 γ-环糊精 ;Cyclomaltooctaose Cyclooctaamylose Schardinger γ-Dextrin
应用 环糊精在化学领域的用途 环糊精是一种有价值的化学试剂。当存在它的时候,荧光色素的荧光强度会显著增大,故可用于蛋白质、氨基酸的分析;还可用它来分离长链有机化合物、外消旋体等。此外由环糊精制成的吸附剂能用作色谱分析的吸附。还可以作络合剂,也可用于酶活性研究,组织培养剂。本品应密封于干燥处保存.
