They rank the atoms around a stereocenter in a standard way, allowing the relative position of these atoms in the molecule to be described unambiguously. An often cited example of the importance of stereochemistry relates to the thalidomide disaster. 1957 in Germany, prescribed for treating morning sickness in pregnant women. Accordingly, it is incorrect to state that one stereoisomer is safe while the other is teratogenic.

Strict regulations and controls have been enabled to avoid its use by pregnant women and prevent developmental deformations. This disaster was a driving force behind requiring strict testing of drugs before making them available to the public. Mechanism of action in thalidomide teratogenesis”.

First, it is shown in the same arrangement as the lead image. This is the unionised form. It is also shown in the ionized form, after the carboxyl group has lost a hydrogen atom, which introduces a negative charge, and the amino group has gained a hydrogen, which introduces a positive charge. Tautomerism is relevant to the behavior of amino acids and nucleic acids, two of the fundamental building blocks of life.

It is typically associated with polar molecules and ions containing functional groups that are at least weakly acidic. It is distinct from prototropic tautomerism, and involves processes with rapid reorganisation of bonding electrons.
