What are Epimers?

Epimers are stereoisomers that differ in configuration at only one chiral center.

D-glucose vs. L-glucose

D-glucose and L-glucose differ in their spatial arrangements around all their chiral centers.

Epimers and Drug Response

Understanding epimers helps explain why different individuals react differently to the same medication.

Chiral Centers in Synth.

Chiral centers are essential for preparing optically active molecules with specific enantiomeric purities in synthetic chemistry.
