    Lipoproteins are conjugated proteins having polypeptides in association with lipids. Immunoglobulins are the constituent of antibodies. Inteferons (INFs) are a group of three vertebrate glycoproteins (i.e. a, b, g,) Out of these three a & b are produced within virally infected cells. Interferon induces among adjacent cells, as antiviral state by inducing synthesis of the enzymes which inhibit the viral production cycle.
