enantiomers. The Four Aldotetroses CH O CH 2 OH H OH H OH CH O CH 2 OH HO H H OH D-Erythrose D-Threose D-Erythrose and D-threose are diastereomers. CH O CH 2 OH HO H HO H Enantiomers are molecules that have the characteristic of chirality, in which their structures are nonsuperimposable mirror images of each other. Chirality is an important characteristic in many biologically important molecules, as illustrated by the examples of structural differences in the enantiomeric forms of the monosaccharide glucose or the amino acid alanine (Figure \(\PageIndex{4}\)). Two enantiomers of chiral drugs have been often known to show different pharmacological activities, one enantiomer showing the desired pharmacological activity whereas the other enantiomer showing the undesired side effect or no activity. 1 Consequently, the pharmacological and pharmacokinetic properties of each of the two enantiomers should be tested at each stage of developing, launching Enantiomers are stereoisomers that are non-superimposable mirror images, meaning that one enantiomer will be the mirror image of the other enantiomer.

The stereoisomers are any two molecules that fulfill the following two requirements: Both molecules must have the same molecular formula, and Both molecules must have the same atom connectivity. So, what’s the difference then enantiomers. The Four Aldotetroses CH O CH 2 OH H OH H OH CH O CH 2 OH HO H H OH D-Erythrose D-Threose D-Erythrose and D-threose are diastereomers. CH O CH 2 OH HO H HO H Enantiomers are two molecules that are nonsuperimposable mirror images: And this is what we had for our pairs of stereoisomers, they were nonsuperimposable mirror images – enantiomers. The lesson is that enantiomers are stereoisomers.
