Any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy source in the diet of animals. These compounds are produced by photosynthetic plants and contain only carbon, hydrogen, and oxygen, usually in the ratio 1:2:1.

carbohydrates
Carbohydrates are biomolecules composed of carbon, hydrogen, and oxygen, and they serve as a major source of energy in our diet. Polysaccharides are large carbohydrates made up of multiple sugar units joined together, forming complex structures with various functions such as energy storage (e.g., starch) or structural support (e.g., cellulose). In summary, all polysaccharides are carbohydrates, but not all carbohydrates are polysaccharides.
