2 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Sucrose \Su"crose`\, n. [F. sucre sugar. See {Sugar}.] (Chem.) A common variety of sugar found in the juices of many plants, as the sugar cane, sorghum, sugar maple, beet root, etc It is extracted as a sweet, white crystalline substance which is valuable as a food product, and being antiputrescent, is largely used in the preservation of fruit. Called also {saccharose}, {cane sugar}, etc By extension, any one of the class of isomeric substances (as lactose, maltose, etc.) of which sucrose proper is the type Note: Sucrose proper is a dextrorotatory carbohydrate, {C12H22O11}. It does not reduce Fehling's solution, and though not directly fermentable, yet on standing with yeast it is changed by the diastase present to invert sugar (dextrose and levulose), which then breaks down to alcohol and carbon dioxide. It is also decomposed to invert sugar by heating with acids, whence it is also called a {disaccharate} From WordNet r 1.6 [wn]: sucrose n : a complex carbohydrate found in many plants and used as a sweetening agent [syn: {saccharose}]
