Now, look at the structures of D -glucose …
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. WebDec 17, 2024 · Therefore, a molecule with five chiral centers can have up to 2 5 or 32 possible stereoisomers! As the number of chiral centers increases, the number of possible stereoisomers for that compound increases rapidly. For example, the molecule shown here has two chiral centers.
