They are made up of carbon, hydrogen, oxygen. The literally meanings of carbohydrates are the hydrated carbons. Carbohydrates also called sugar‖ General formula As the carbohydrates are the hydrated carbons so the no. of water molecules attach to the carbon are equal in number to the no. of carbon atoms. Thus the general formula is given as Cn (H2O) n. here ―n‖ is the whole number. Exception to the general formula and definition There are some such carbohydrates which contain nitrogen, phosphorous or sulphur also in addition to carbon. Rhamnose has a Formula C6H12O5. Also all the compounds having formula Cn(H2O) n may not be carbohydrates formic, acetic and lactic acids are some examples of such compounds.
