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).

WebJan 8, 2024 · The issue with the chiral flag not set in the SD-file is a V2000 problem, not V3000. The fifth entry in the counts line of a V2000 molfile encodes, whether the structure is a racemate or not (0 or 1). For racemates DataWarrior must normalise the configuration, because DataWarrior stores canonical structure representations.
