Carbohydrates.

CARBOHYDRATES: -

Carbohydrates are the one of the many other biomolecules of life which are in great use the living organisms and are composed of Carbon(C), Hydrogen(H) and Oxygen(O) molecules. The carbohydrates are technically the hydrates of carbon and structurally they are most accurately viewed as the aldoses and ketoses. Carbohydrates play an important role by storing energy in the form of glucose and starch. The hydrogen and oxygen atoms are combined in the ratio of  2:1, having an empirical formula of Cm(H2O)n.
The 'Biochemistry' based term of carbohydrate is 'Saccharide' which includes group of sugars, starch and cellulose.
The Saccharide are chemically grouped into four different types such as, Monosaccharides, Disaccharides, Olligosaccharides and the Polysaccharide.
These four groups of Saccharides can be further divided to several other groups of compounds based on their chemical and structural compositions and how they react or behave on coming in contact with any other compounds.
The carbohydrate derivatives have the ability of forming 'Osazone' complex when sugars are reacted with excess of phenylhydrazine.
The sugar classes of carbohydrates are determined by the pyranose and furanose forms.
