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. The existence of these molecules is determined by concept known as chirality. The word “chiral” was derived from the Greek word for hand, because our hands are good example of chirality ...

http://butane.chem.uiuc.edu/jsmoore/marvin/help/formats/cxsmiles-doc.html WebThe "chiral flag" is a feature that was used in MDL v2000 mol files, but was superseded by Enhanced Stereo Groups, which are much more flexible, in the v3000 format.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 ...

WebFix chiral flag from cxsmiles input. By default the molecule absolute stereoconfiguration (relative or absolute chirality - chiral flag) is specified at the extended part of the cxsmiles string. If it is missing it is assumed to be absolute by default (see Molecule absolute stereoconfiguration above).

Webif this flag is true, any existing atomic chiral tags will be replaced If the conformer provided is not a 3D conformer, nothing will be done. NOTE that this does not check to see if atoms are chiral centers (i.e. all substituents are different), it merely sets the chiral type flags based on the coordinates and atom ordering. Weblists, the chiral flag setting, and the Ctab version. Atom block: Specifies the atomic symbol and any mass difference, charge, stereochemistry, and associated hydrogens for each atom. Bond block: Specifies the two atoms connected by the bond, the bond type, and any bond stereochemistry and topology (chain or ring properties) for each bond.

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).
