WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers). WebNo chiral flag set means that only the relation is known between the tetrahedral stereo centers. The stereocenter could be either of the two stereomers (as drawn and the mirror image) or a mixture of the two. In JChem the chiral flag representation of MDL is not considered by default and all molecules are treated as chiral: Table 8.

WebA chiral molecule is an enantiomer of its mirror image. As well, a chiral molecule and its mirror image are enantiomers. Diasteriomers have multiple stereocenters, each diasteriomer also often has an enantiomer. You're thinking of Meso compounds where a Diasteriomer … But this one right here, that is a chiral center.

WebOne of the most interesting types of isomer is mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another.
