What is Isomerism?
The phenomenon where two or more compounds share the same molecular formula but differ in structural arrangement or spatial orientation of atoms. Types include constitutional (structural), geometric (cis/trans), and optical (enantiomers/diastereomers) isomerism.

The phenomenon where two or more compounds share the same molecular formula but differ in structural arrangement or spatial orientation of atoms. Types include constitutional (structural), geometric (cis/trans), and optical (enantiomers/diastereomers) isomerism.
Drug design: enantiomers often have different biological activities (thalidomide S=teratogenic, R=therapeutic). Flavor and fragrance: (R)-carvone (spearmint), (S)-carvone (caraway). Amino acids: all naturally occurring are L-configuration. Sugars: D-glucose (blood sugar) vs L-glucose (not metabolize…
Optical isomers can have dramatically different toxicities and therapeutic effects. Thalidomide caused birth defects due to racemic mixture use — now single enantiomer drugs required. (S)-ibuprofen is the active form; (R)-ibuprofen converts slowly in vivo. Always verify stereochemistry when working …
