An antibody molecule has a total number of how many polypeptide chains:
- A
1
- B
2
- C
3
- D
4
Antibody (or immunoglobulin) molecules are glycoproteins composed of one or more units; each containing four polypeptide chains; two identical heavy(H) and two identical light chains(L) which are connected with each other by disulfide bridge and form a 'Y' shaped structure.
An antibody molecule has four polypeptide chains: two identical heavy(H) and two identical light chains(L). Hence, option A is wrong.
