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.
