haptoglobin[′hap·tə‚glō·bən] (biochemistry) An alpha globulin that constitutes 1-2% of normal blood serum; contains about 5% carbohydrate. haptoglobin
haptoglobin [hap´to-glo″bin] a group of serum alpha2-globulin glycoproteins that bind free hemoglobin; three phenotypes, with differing abilities to bind hemoglobin, are distinguished electrophoretically.hap·to·glo·bin (HP), (hap'tō-glō'bin), [MIM*140100 & MIM*140210] A group of α2-globulins in human serum, so called because of their ability to combine with hemoglobin, preventing loss in the urine; variant types form a polymorphic system, with α- and β-polypeptide chains controlled by separate genetic loci. Levels are decreased in hemolytic disorders and increased in inflammatory conditions or with tissue damage. [G. haptō, to grasp, + hemoglobin] haptoglobin (hăp′tə-glō′bĭn)n. A plasma protein that is a normal constituent of blood serum and functions in the binding of free hemoglobin in the bloodstream.haptoglobin A protein in the circulation that migrates in the α2 portion of serum subjected to electrophoresis, a so-called acute phase reactant that ↑ in serum in acute inflammation or infection, stress, or necrosis Role Bind Hb released from RBCs undergoing hemolysis, preventing the accumulation of Hb in plasma; after iron has been removed, the haptoglobin-bound Hb is eliminated by the reticuloendothelial system.hap·to·glo·bin (hap'tō-glō'bin) A group of α2-globulins in human serum, so called because of their ability to combine with hemoglobin; variant types form a polymorphic system, with α- and β-polypeptide chains controlled by separate genetic loci. [G. haptō, to grasp, + hemoglobin]haptoglobin Alpha2 -globulin, a plasma protein that binds free haemoglobin to form a complex too large to pass out of the kidneys into the urine.HaptoglobinA blood protein made by the liver. Its main role is to save iron by attaching itself to any hemoglobin released from a red cell.Mentioned in: Haptoglobin Test, Protein ElectrophoresisAcronymsSeeHPThaptoglobin
