👉 In the context of chemistry and molecular biology, a "parasubstituted molecule" refers to an organic compound that is substituted in a different way than its parent substance. This can be done by adding a substituent to the parent molecule or through the addition of a functional group on the parent molecule. For example, a benzene ring (C6H6) can be substituted with an ethane ring (C2H4) to form the compound C6H10O2
