Why Some Molecules Have Evil Twins

The video explains enantiomers, molecules that are mirror images of each other, like left and right hands. Despite having similar properties, they interact differently with receptors, leading to varied effects. For instance, one enantiomer of a nasal decongestant can open nasal passages, while its mirror image can cause euphoria and addiction. The video also discusses other enantiomers like Penicillamine and Carvone, highlighting their distinct effects. Converting one enantiomer to another is complex, requiring breaking strong covalent bonds, which is often misunderstood by those attempting to make drugs from nasal sprays.
