WebCarbohydrates have one or more chiral centers- carbons with 4 different groups attached, giving rise to the possibility of stereoisomers Generally, a compound containing “n” chiral centers can maximally have 2“n” stereoisomers. Enantiomers are stereoisomeric compounds whose structures are nonsuperimposible mirror images of each other.
