Question

Why is an antibody molecule represented as h2l2?

Answer 1

Humoral immune response orAntibody Mediated Immunity (AMI) It is mediated by antibodies present in blood and lymph. ... (a)Each antibody molecule has four peptide chains, i.e. two small called light (L) chains and two longer called heavy (H) chains. Hence, an antibody is represented as H2L2.

Answer 2

An Antibody is a 'Y'  shaped structure , that has two types of chains

one is light and another is heavy.

Each antibody has a four peptide two small or light chain refers as L2 and two heavy chain that are refer as H2.

Antibodies are the immunoglobulins that may react specifically with their antigen that on antigen binding site and regulate their production. Antibody is produced by B cell and these Antibodies are present on its membrane.
