Discuss the role of chemical structures in the physicochemical factors of drugs?

I think they want you to discuss charality.

Chirality is a property of individual molecules.  If a molecule is chiral then we know that the molecule has two enantiomeric forms (which are almost identical but are actually different molecules).  I like to think of this as the 'twin' property.  If a molecule is chiral then we know that it has a twin (an enantiomer).  If a molecule is not chiral (achiral) then it is unique and does not have a twin.



A drug molecule needs to be a certain position to fit the enzyme that processes it or to fit where it's supposed to be effective, like at a protein channel, ion channel, etc.
