Stereochemistry
Every organic compound needs an unambiguous name that clearly delineates all structural features of the molecule. The same is true for stereocenters. Because a stereocenter can exist in only two absolute configurations, IUPAC nomenclature is easily modified to name stereocenters. To name a stereocenter, we assign priority to the groups attached to the stereocenter, and then apply a label based upon the direction in which priorities decrease. Therefore, on the basis of the importance of stereoisomerism in drug action, student of Faculty of Pharmacy should have more practicing studies on overall comparation of molecules to find out what would be crucial for drug activity related to their molecular structure.
