Primary function of carbohydrates - Fuel for body - energy and biosynthesis Classification of carbohydrates - - aldoses vs ketoses - number of carbons (ex: triose = 3 carbons) Constitutional isomers - same molecular formula, different connectivity Stereoisomers - Compounds with the same structural formula but with a different arrangement of the atoms in space. Enantiomers - mirror images of each other Distereomers - stereoisomers that are not mirror images Epimers - differ in ...
