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).

WebThe "chiral flag" is a feature that was used in MDL v2000 mol files, but was superseded by Enhanced Stereo Groups, which are much more flexible, in the v3000 format. It would be useful to have some infrastructure that allows us to "translate" the stereochemistry read from a v2000 mol block into Enhanced Stereo Groups. If my understanding of the ...
