The word sucrose was coined in 1857, by the English chemist William Miller [6] from the French sucre ("sugar") and the generic chemical suffix for sugars -ose. The abbreviated term Suc is often used for sucrose in scientific literature. The name saccharose was coined in 1860 by the French chemist Marcellin Berthelot. [7]
Three common examples are sucrose, lactose, and maltose. Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides). The most common types of disaccharides—sucrose, lactose, and maltose—have 12 carbon atoms, with the general formula C 12 H 22 O 11.
Lactose, maltose, and sucrose are all compound sugars, disaccharides, with the general formula C 12 H 22 O 11. They are formed by the combination of two monosaccharide molecules with the exclusion of a molecule of water. [72] Lactose is the naturally occurring sugar found in milk. A molecule of lactose is formed by the combination of a molecule ...
The refining process completely removes the molasses from cane juice or beet juice to give the disaccharide white sugar, sucrose. It has a purity higher than 99.7%. [1] Its molecular formula is C 12 H 22 O 11. [2]
The iron sucrose molecule is a polymer with two main molecules; sucrose (chemical formula C 12 H 22 O 11) and an iron (III) hydroxide (Na 2 Fe 5 O 8 •3(H 2 O)). These two components are in solution together, but are not bound to one another. [2] Iron sucrose is a type II complex, with two oxygen atoms bonded to each iron atom. [3]

When sucrose is dehydrated, heat is given out to the surroundings in an exothermic reaction, while graphite and liquid water are produced by the decomposition of the sugar: [3] C 12 H 22 O 11 ( s ) + H 2 SO 4 ( aq ) + 1/2 O 2 ( g ) → 11 C ( s ) + CO 2 ( g ) + 12 H 2 O ( g ) + SO 2 ( g )
Sucrose is a non-reducing sugar, so will not test positive with Benedict's solution. To test for sucrose, the sample is treated with sucrase. The sucrose is hydrolysed into glucose and fructose, with glucose being a reducing sugar, which in turn tests positive with Benedict's solution. [citation needed].
