應用

D-Xylose, an aldopentose, is used as a feed stock to produce the non-caloric sweetener, xylitol and commercially valuable ethanol. D-Xylose may be used in intestinal function research to test for small intestinal malabsorption.

生化/生理作用

D-Xylose, a principle hemicellulosic sugar in plants and hardwoods, is a main building block for xylan.

Bacterial ribosomes frequently translate to the 3' end of an mRNA without terminating at a stop codon. Almost all bacteria use the transfer-messenger RNA (tmRNA)-based trans-translation pathway to release these "nonstop" ribosomes and maintain protein synthesis capacity. trans-translation is essential

Microbial conversion of lignocellulosic feedstocks into biofuels remains an attractive means to produce sustainable energy. It is essential to produce lignocellulosic hydrolysates in a consistent manner in order to study microbial performance in different feedstock hydrolysates. Because of the potential
