描述

一般說明

D-Arabinose is a rare aldopentose, and is rarely utilized by enteric bacteria as a source of carbon and energy. It is also found in the aloins of the plant genus Aloe and as a constituent of the polysaccharide of the bacterial genus Mycobacterium. Some of the enteric bacteria like Escherichia coli K-12 can mutate to utilize D-arabinose.

應用

D-(-)-Arabinose has been used as an inducer of λ-RED recombinant gene expression.

生化／生理作用

D-阿拉伯糖是一种还原糖。它是一种 D-核糖的戊糖类似物，是组成分支杆菌细胞壁阿拉伯半乳聚糖的成分。也是酵母中 D-红抗坏血酸合成的底物。
