- adj. Describing the relationship between two groups attached to the same atom which, if replaced, would generate compounds that are enantiomers
Sorry, no etymologies found.
A small level of enantiotopic deuterium labeling of polyalkylisocyanates -say 10%, an incredibly small perturbation - causes the helical polymers to be wound entirely in one sense.
If a pair of nuclei can be interchanged by an improper rotational symmetry operation of the molecule then they are chemically equivalent and are called enantiotopic. e.g. pair of protons attached to the alpha-Carbon in glycine amino acid (they are not chemically equivalent if glycine is part of a polypeptide chain).
