Sugar has the chemical formulate C 12H 22O 11 and is constructed from different elements than salt: carbon, hydrogen and oxygen. While sugar qualitatively resembles table salt (often confused in the kitchen), the two have distinctly different physical and chemical properties. There are various types of sugar derived from different sources.

Molar mass of Code: Select all C12H22O11 [/url] Code: Select all {1} is 342.2979 ± 0.0003 g/mol Code: Select all {2} Code: Select all {1} Wikipedia: Sucrose

First the molecular formula of sucrose (C 12 H 22 O 11) is used to calculate the mass percentage of the component elements; the mass percentage can then be used to determine an empirical formula. According to its molecular formula, each molecule of sucrose contains 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar is a refined form of sucrose. In the body, compound sugars are hydrolysed into simple sugars.

Sucrose. Sucrose or table sugar is obtained from sugar cane or sugar beets. Sucrose is made from glucose and fructose units. The glucose and fructose units are joined by an acetal oxygen bridge in the alpha orientation. The structure is easy to recognize because it contains the six member ring of glucose and the five member ring of fructose.
