One of a group of compounds including the sugars, starches, and gums, which contain six (or some multiple of six) carbon atoms, united with a variable number of hydrogen and oxygen atoms, but with the two latter always in proportion as to form water; as dextrose, C6H12O6.
One of the three main constituents of foods. Carbohydrates are composed mainly of sugars and starches.
Carbon, hydrogen, and oxygen containing biomolecules with a formula of (CH2O)n, that is carbon is hydrated, hence the name. Chemically, it is an aldehyde or ketone derivative of a polyhydric alcohol, particularly of penta- and hexahydric alcohols. The most important carbohydrates are starches, sugars, cellulose, and gums.
One of the three nutrients that supply calories (energy) to the body. Carbohydrates are needed for normal body function. There are two basic kinds of carbohydrates: simple (sugars) and complex (starches and fiber).
