The term carbohydrate or hydrates of carbon is derived from its basic elemental formula in which carbon is bonded to oxygen and hydrogen, present in the same ratio as water. A carbohydrate is known as a saccharide. They are generally defined as polyhydroxy aldehydes or polyhydroxy ketones or substances which yield such compounds on hydrolysis.
Carbohydrates have the empirical formula (CH2O)n. Based on the structures, there are three major classes of carbohydrates: Monosaccharides, Oligosaccharides, and Polysaccharides. Carbohydrates are the most abundant biomolecules on earth. For example, the green plant produces starch for energy storage, and similarly, glycogen is the main storage form of glucose in animals, fungi, and bacteria.
In most non-photosynthetic cells, the oxidation of carbohydrates is the central energy-producing pathway. Our body breaks down carbohydrates into glucose. Some of the carbohydrates have a sweet taste and are called sugars
The following tests are involved in Biochemistry practical for the identification of carbohydrates in the given sample:
- Fehling’s Test
- Molisch’s Test
- Benedict’s Test
- Barfoed’s Test
- Seliwanoff’s Test
- Iodine Test
