PEGs that are activated at each end with the same reactive moiety are known as "homobifunctional", whereas if the functional groups present are different, then the PEG derivative is referred as "heterobifunctional" or "heterofunctional". The chemically active or activated derivatives of the PEG polymer are prepared to attach the PEG to the desired molecule.
