H chain (heavy chain) any of the large polypeptide chains of five classes that, paired with the L or light chains, make up the antibody molecule of an immunoglobulin; heavy chains bear the antigenic determinants that differentiate the classes of immunoglobulins. See also heavy chain disease.
J chain a polypeptide occurring in polymeric IgM and IgA molecules.
L chain (light chain) either of the two small polypeptide chains (molecular weight 22,000) that, when linked to H or heavy chains by disulfide bonds, make up the antibody molecule of an immunoglobulin monomer; they are of two types, kappa and lambda, which are unrelated to immunoglobulin class differences.
open chain a series of atoms united in a straight line; components of this series are related to methane.
chain reaction a chemical reaction that is self-propagating; each time a free radical is destroyed a new one is formed.
