Study Notes

Carbohydrates

  • Polysaccharides consist of chains of monosaccharide or disaccharide units.
  • The main function of carbohydrates in the body is to provide energy and structure.
  • Aldoses and ketoses are classified based on whether the carbonyl group is located at the end of the chain (aldose) or within the chain (ketose).
  • Carbohydrates can be classified as triose, tetrose, pentose, or hexose based on the number of carbons they contain, with three, four, five, or six carbons respectively.
  • The empirical formula for carbohydrates is CH2O.
  • Disaccharides are formed by two monosaccharides covalently linked by a glycosidic bond.

Test your knowledge of carbohydrates by exploring their structure and functions in the body. Learn about the empirical formula of carbohydrates and their role as a source of energy, storage form of energy, and cell membrane component.
