一般說明

D-(+)-海藻糖是由两分子 α-葡萄糖组成的二糖。它在多种细胞冷冻培养基中作为冷冻保护剂。用作运输介质中的保护剂。它主要存在于支持低湿休眠(无水生活)的物种中。它可作为微生物中的碳水化合物储备,并保护它们免受不利条件的影响,如热、冷、脱水、干燥和氧化。海藻糖可以作为影响蛋白质折叠的化学伴侣。已知它可防止产生淀粉样蛋白和 β-淀粉样蛋白堆积。在亨廷顿蛋白聚集中也观察到了海藻糖的类似作用。因此,它可以作为阿尔茨海默氏′病和亨廷顿′病的保护剂。海藻糖能更好的刺激 沙门氏菌 细胞的初期生长。

應用

D-(+)-海藻糖可被用作某些细胞培养的碳水化合物储备,用以抵御环境压力。 它还可用于作为单克隆抗体生物制药配方的蛋白稳定剂。
