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.
