It is worth pointing out what exactly enantiomers are: exact mirror images of each other. Most of what enantiomers do and don't do can be understood by remembering that basic definition and applying it logically. First, let's compare a chiral compound to an achiral one. Imagine an achiral molecule in front of a (molecular-sized) mirror. The orientation does ...

I think a simplified version of the enzyme example is helpful here. Consider this image of binding a molecule to a receptor: Using a model of enantiomers where the attached groups are just differently shaped blocks, it is clear to see that if one enantiomer fits, the other one can not, regardless of the way it is oriented. The different rotation of light is ...
