Medical Definition of carbohydrate. : any of various neutral compounds of carbon, hydrogen, and oxygen (as sugars, starches, and celluloses) most of which are formed by green plants and which constitute a major class of animal foods.

Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. The origin of the term carbohydrate is based on its components: carbon (carbo) and water (hydrate). Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.
