For example, tartaric … seth m hays wikiWebNotice 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). There are about 20 amino acids normally found in the human body. All of them are the L-isomers. the thorntonitesWebCHIRALITY. Because of the tetrahedral geometry of saturated carbon and the associated three-dimensional properties, molecules can have chirality as one stereochemical feature.
