WebJan 23, 2024 · All objects may be classified with respect to a property we call chirality (from the Greek cheir meaning hand). A chiral object is not identical in all respects (i.e. superimposable) with its mirror image. An achiral object is identical with (superimposable on) its mirror image.

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). WebJul 3, 2024 · A chiral center is defined as an atom in a molecule that is bonded to four different chemical species, allowing for optical isomerism. It is a stereocenter that holds a set of atoms (ligands) in space such that …
WebThey are either geometrical isomers or compounds containing two or more chiral centres. A Diastereomer is called erythro if its Fischer projection shows similar groups on the same side of the molecule. It is called threo if similar groups are on the opposite sides of the Fischers projection.
