What is a carbohydrate?
A carbohydrate is a basic energy source of nutrition. Carbohydrates can be simple like sugars or complex like fibers and starches. Fruits and vegetables are good sources of carbohydrates.
Carbohydrate or saccharide (from Greek: sakckaron, sugar) is an essential component of all living organisms and it's, in fact, the most abundant class of biological molecules. The name carbohydrate, which literally means "carbon hydrate", stems from their chemical composition, which is roughly (C - H2O)n, where n is bigger/equal to 3.
Carbohydrate molecule is an aldehyde or ketone derivative of a polyhydroxy alcohol that is synthesized by living cells. Carbohydrates can be grouped either by their size into mono-, oligo-, and polysaccharides, or by their functional group into aldehyde or ketone derivatives.
Common carbohydrates include bread, cake, potatoes, and noodles. They are compounds which contain carbon, hydrogen, and oxygen and can be broken down to supply the body with glucose.
