random coil conformation, the force to extend the macroion appears as a result of

the electrical interaction among charged groups and counter ions.

**Spherical Macroions**If the macroion is a flexible chain in therandom coil conformation, the force to extend the macroion appears as a result of

the electrical interaction among charged groups and counter ions.
