Answer

Explanation

Antibodies are the proteins (glycoproteins) called immunoglobulins. These are produced by the lymphocytes in response to entry of a foreign substance or antigen into the body. Antibodies are of five types, e.g. IgG, IgM, IgA, IgD, IgE. Lipoproteins are the micellar complex of protein and lipids.
Steroids are a group of lipids derived from a saturated compound cyclopentano perhydroph- enanthrene, which has a nucleus of four rings. Prostaglanclin is a group of organic compounds derived from essential fatty acids and causing a range of physiological effects in animals.
