sugar (redirected from blood sugar)

sugar, compound of carbon, hydrogen, and oxygen belonging to a class of substances called carbohydrates. Sugars fall into three groups: the monosaccharides, disaccharides, and trisaccharides. The monosaccharides are the simple sugars; they include fructose and glucose. The disaccharides are formed by the union of two monosaccharides with the loss of one molecule of water. Disaccharides include lactose, maltose, and sucrose. Less well known are the trisaccharides; raffinose is a trisaccharide present in cottonseed and in sugar beets. Sugars belong to two families denoted by the letter d- or l- written before the name of a sugar. The families are related to glyceraldehyde CH₂OHCHOHCHO, which can exist in two three-dimensional forms that are mirror images of each other. The isomer of glyceraldehyde that rotates plane polarized light clockwise is labeled d-glyceraldehyde; all natural sugars can be derived from this substance and thus belong the the d family. Although l-sugars can be prepared in the laboratory, they cannot be utilized by animals.

sugar

Any of numerous sweet, colourless organic compounds that dissolve readily in water and occur in the sap of seed plants and the milk of mammals. Sugars (whose names end in -ose) are the simplest carbohydrates. The most common is sucrose, a disaccharide; there are numerous others, including glucose and fructose (both monosaccharides); invert sugar (a 50:50 mixture of glucose and fructose produced by enzyme action on sucrose); and maltose (produced in the malting of barley) and lactose (both disaccharides). Commercial production of sugars is almost entirely for food.
