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 ...

What is the general formula for a carbohydrate? - Cx(H2O)y How do you determine the number of stereoisomers for a given carbohydrate? - 2^n where n= number of stereocenters Distinguish between the D and L designations for carbohydrates. - In the L form the hydroxy group is on the bottom left closest to the CH2OH group in the frame of a Fischer projection In the D form the OH is on the bottom right What are anomers? - Diastereomers formed by the cyclization of carbohydrates (*note they ...
