The organic fructose molecule was subsequently discovered by Dubrunfaut in 1847. [6] He also discovered maltose, although this discovery was not widely accepted until it was confirmed in 1872 by Cornelius O'Sullivan. [7]
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]
Achard revived the discovery by Marggraf in 1747 that sugar beets contained sugar, and devised a process to produce sugar from sugar beets. Beginning in 1789, he planted various sugar-bearing plants on his manor in Kaulsdorf near Berlin.
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].
Monosaccharides are the building blocks of disaccharides (such as sucrose, lactose and maltose) and polysaccharides (such as cellulose and starch). The table sugar used in everyday vernacular is itself a disaccharide sucrose comprising one molecule of each of the two monosaccharides D-glucose and D-fructose. [2]
