1,2,3,5-Tetra-O-acetyl-D-xylofuranose

四乙酰基-D-木糖,

1,2,3,5-Tetra-O-acetyl-D-xylofuranose is a lectin that has been shown to have an affinity for bacterial cells. It has been shown to be effective against Gram-positive and Gram-negative bacteria, with the exception of mycobacteria. 1,2,3,5-Tetra-O-acetyl-D-xylofuranose binds to the terminal sugar of the cell wall carbohydrate chains of these cells by means of its oligosaccharide side chain. The binding causes conformational changes in the bacterial membrane and disrupts the ion gradient across it. This leads to an influx of water into the cell and subsequent death.

1,2,3,5-tetra-O-acetyl-D-xylofuranose (TAX) is a monosaccharide derivative that belongs to the furanose family. It is synthesized from D-xylose, which is a common component of plant polysaccharides.
