enantiomer

2 Or Each
a: Enantiomer ~
b: hands
What: "Enantiomers are compounds with the same molecular structure that have a slightly differing arrangement of their atoms in space which are non-superimposable on each other. Enantiomers are like hands; while looking at the back of your hands it is impossible to place them on one another so that all of your digits line up."

Two Feet Also Works....
a: Enantiomer ~
b: left and right hand
What: "A pair of enantiomers are like a left and right hand (i.e. non-superposable mirror images), and are said to be
chiral (from the Greek cheir meaning hand). All other molecules are achiral (i.e. without chirality). Chiral molecules contain an atom (often a carbon atom) bearing four different substituents. Such an atom is known as a stereogenic centre. Molecules can contain more than one stereogenic centre and these may or may not be themselves chiral. Chiral molecules have no plane(s) of symmetry or centre of inversion and it is often
easier to try to spot these to prove that a molecule is achiral rather than try to draw and superimpose mirror images."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
