PATHOLOGY

Detailed explanation-1: -1. Antibodies are Y-shaped proteins made in great abundance by our immune system. While antibodies come in a few shapes and sizes, the most familiar of these are the Y-shaped proteins known as IgG antibodies (immunoglobulin G).

Detailed explanation-2: -An antibody, also known as an immunoglobulin, is a Y-shaped structure which consists of four polypeptides-two heavy chains and two light chains. This structure allows antibody molecules to carry out their dual functions: antigen binding and biological activity mediation.
