木糖是最早从木材中分离出来的糖 Xylose is a sugar first isolated from wood, 并以此命名。木糖被分类为醛戊糖类型的单糖 and named for it. Xylose is classified as a monosaccharide of the aldopentose type, 这意味着它包含五个碳原子并包含一个醛官能团。它是半纤维素的前体 which means that it contains five carbon atoms and includes an aldehyde functional group. It is the precursor to hemicellulose, 生物质的主要成分之一。 (维基百科) one of the main constituents of biomass. (Wikipedia)
