Answer 1

Answer:

Antibodies are immune system-related proteins called immunoglobulins. Each antibody consists of four polypeptides– two heavy chains and two light chains joined to form a "Y" shaped molecule. The amino acid sequence in the tips of the "Y" varies greatly among different antibodies.

The 5 types - IgG, IgM, IgA, IgD, IgE - (isotypes) are classified according to the type of heavy chain constant region, and are distributed and function differently in the body. IgG is the main antibody in blood. ... IgM is made up of 5 antibodies. IgM has a key role in the initial immune system.
