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 ...

Alcohol - Ketone - Amine - Ether - Amide - Ester - functional groups - Alkyl - An alkane missing a hydrogen Aromatic compound - Cyclic, planar, with every atom of the aromatic ring having a p orbital, while obeying hackles rule of 4n+2 pi electrons Vinyl - Hydrolysis Reaction - Carboxylic Acid - pKa ~ 5 Enantiomers - stereoisomers that are non super imposable mirror images Diastereomers - - Same molecular formula, same bond connections, NOT mirrors...
