To distinguish the two forms, they are often designated right handed or left-handed. In the case of 108 SCIENTIFIC AMERICAN January 1990 some familiar chiral entities-hands or screws, for instance-the meaning of right-and left-handed is clear, but for objects such as an elm tree with many branches or for generally irregu

A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers; they are often distinguished as either "right-handed" or "left-handed" by their absolute configuration or some other criterion. The two enantiomers have the same chemical properties, except when … See more In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called … See more The chirality of a molecule is based on the molecular symmetry of its conformations.
