Hello,

• Given below are some salient features of the structure of Antibody:

• Antibodies are proteins produced by B-lymphocytes in the body in response to antigens.

• They are made up of two light chains and two heavy chains.

• They have inter-chain as well as intra-chain disulfide bonds. The portion of the light and heavy chain which interact with antigens is called antigen-binding site.

----Due to certain constraints I won't be able to add image in the answer, but you can check out the link providing the image of the antibody as given in the NCERT Biology -

I hope you find the answer helpful.

Thank you.
