IMMUNOLOGY

Detailed explanation-1: -Antibody molecules are roughly Y-shaped molecules consisting of three equal-sized portions, loosely connected by a flexible tether.

Detailed explanation-2: -What do antibodies look like? Each antibody structure consists of two heavy chains and two light chains, which join to form a Y-shaped molecule. Each type of antibody has a different amino acid sequence at the tips of the “Y” which is why each antibody is shaped differently.

Detailed explanation-3: -A typical antibody molecule is Y-shaped, with two identical antigen-binding sites at the tips of the Y and binding sites for complement components and/or various cell-surface receptors on the tail of the Y. Each B cell clone makes antibody molecules with a unique antigen-binding site.

Detailed explanation-4: -An antibody is a Y-shaped protein produced by B cells to identify and neutralize antigens in the body.
