a-D-吡喃木糖, a-D-Xylopyranose

D-Xylopyranose is a sugar with the chemical formula C5H10O5. It is a potent antagonist of sweet taste, which may be due to its ability to bind to the sweet receptor on the tongue. D-Xylopyranose can also be used as an analytical reagent in analytical chemistry and has been shown to have anti-inflammatory properties. D-Xylopyranose can be hydrolyzed by acid or base into two molecules of l-arabinose and one molecule of water, and is composed of five carbon atoms, 10 hydrogen atoms, one oxygen atom, and one hydroxyl group. The structure of D-xylopyranose contains a terminal residue (e.g., l-arabinose) that can form glycosidic bonds with other sugars such as glucose or sucrose to form disaccharides such as maltose or sucrose.
