Arabinose

Arabinose is a monosaccharide containing five carbon atoms, and including an aldehyde (CHO) functional group. Arabinose is a white crystalline aldose sugar found especially in vegetable gums. D-arabinose is the 2 epimer of D-ribose. It differs from D-ribose by having the opposite configuration at carbon 2. D-arabinose occurs in the polysaccharide arabinogalactan, a neutral pectin of the cell wall of plants and in the metabolites cytosine arabinoside and adenine arabinoside. Well known carbohydrates include glucose, fructose, arabinose, Ribose, fucose, mannose, lyxose and xylose.
