Types of Non-Covalent Interactions | Immunology

Inter-molecular forces of non-covalent bond between antigen and antibody is divided into four basic types:     Type # 1. Electrostatic Interaction: The force between oppositely charged ionic groups on the two protein side chains is known as electrostatic forces (Fig. 5.2a). The force of attrac­tion (F) is inversely proportional to the square of the distance (d) between the charges. [...]
