Cats Paw Analogy

a: Enantiomers ~
b: cat paws

What: "As the IPKat understands them, enantiomers are like a cat's left and right paws: molecules which are identical other than being mirror images of one another. And just like one's paws, left and right versions usually appear in equal quantities (in the laboratory at least) - a racemic mixture. To round off the analogy, nature sometimes endows one paw - or one enantiomer - with much more activity or effectiveness than the other (the IPKat can testify to this having received many a swat from Merpel's favoured left paw)."
