What is sucrose?

sucrose molecule
   Sucrose, or saccharose, is a sugar, C12H22O11, which, together with lactose and maltose, belongs to the important group of carbohydrates known as disaccharides. It is soluble in water, slightly soluble in alcohol and ether-, moderately soluble in dilute alcohol, and crystallizes in long, slender needles. Sucrose is dextrorotatory, rotating the plane of polarized light to the right. Upon hydrolysis, it yields a mixture of glucose and fructose, which are levorotatory, turning the plane of polarized light to the left. Thus the mixture obtained is known as invert sugar, and the process is known as inversion. Inver­sion is carried on in the human intestine through the aid of the enzymes invertase and sucrase, metabolism of Sucrose is extracted chiefly from sugar cane and sugar beet, and is commonly called "cane sugar". When heated to temperatures above 180 °C. (356 °F.), sucrose becomes an amorphous, brown, syrupy substance called "caramel", which is used as a coloring matter in baking.
