WebStereochemistry – Viktor Meyer (1848–97) used the term in 1878 to describe the study of stereoisomers. In 1848, Louis Pasteur demonstrated that tartaric acid has optical activity, … Many biologically active molecules are chiral, including the naturally occurring amino acids (the building blocks of proteins) and sugars. The origin of this homochirality in biology is the subject of much debate. Most scientists believe that Earth life's "choice" of chirality was purely random, and that if … 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.

In a solution, the (−)-form, or See more A stereogenic center (or stereocenter) is an atom such that swapping the positions of two ligands (connected groups) on that atom results in a molecule that is stereoisomeric to the original. For example, a common case is a tetrahedral carbon bonded to … See more Chirality is a symmetry property, not a property of any part of the periodic table. Thus many inorganic materials, molecules, and ions are chiral. Quartz is an example from the mineral kingdom.
