Immunoglobulin G ("IgG") is the main type of the five different types of antibodies found in vertebrates (sharks have only very rudimentary immune factors such as this). "Globulins" are one of five types of protein which are discerned on the basis of their solubility properties.* The antibody molecule is composed of four different polypeptide chains: two larger ones (designated as "H" for heavy) and two smaller chains ("L" for light). Each of these chains (primary structures) are mixes of α-helices and β-pleated sheets, which are the two forms of secondary structure found in the protein world. The four chains are linked together by disulfydryl bonds (cys-cys) as indicated by the dots to make an overall tertiary structure.
