Study Notes

Antibody Structure

Antibodies are proteins called immunoglobulins, consisting of four polypeptides: two heavy chains and two light chains, forming a "Y" shaped molecule.

Antibody Specificity

The amino acid sequence at the tips of the "Y" shape (110-130 amino acids) varies among different antibodies, giving each antibody its specificity.

Antibody Function

The constant region of an antibody determines the mechanism used to destroy antigens.

Antibody Classification

Antibodies are divided into 5 major classes: IgM, IgG, IgA, IgD, and IgE, based on their constant region structure and immune function.
