wood sugar
wood sugar[′wu̇d ‚shu̇g·ər] (biochemistry) xylose wood sugar
wood sug·ard-xylose. See: xylose. sugar (shug'ar) [Ult. fr. Arabic sukkar via L. succarum] A sweet-tasting, low-molecular-weight carbohydrate of the monosaccharide or disaccharide groups. Common sugars include fructose, glucose, lactose, maltose, sucrose, and xylose. Oral or parenteral administration of sugars can prevent hypoglycemia caused by insulin or oral hypoglycemic agents. ClassificationSugars are classified in two ways: the number of atoms of simple sugars yielded on hydrolysis by a molecule of the given sugar and the number of carbon atoms in the molecules of the simple sugars so obtained. Therefore, glucose is a monosaccharide because it cannot be hydrolyzed to a simpler sugar; it is a hexose because it contains six carbon atoms per molecule. Sucrose is a disaccharide because on hydrolysis it yields two molecules, one of glucose and one of fructose.

In diabetes mellitus, fasting blood sugar levels exceed 126 mg/dl.
