haptoglobin

Acid a2-plasma glycoprotein that binds to oxyhaemoglobin that is free in the plasma, and the complex is then removed in the liver. Tetrameric (2 a , 2 b subunits): the existence of two different a chains in humans means that haptoglobins can exist in three variants in heterozygotes.

Haptoglobin

Haptoglobin (abbreviated as Hp) is the protein that in humans is encoded by the HP gene. In blood plasma, haptoglobin binds free hemoglobin (Hb) released from erythrocytes with high affinity and thereby inhibits its oxidative activity. The haptoglobin-hemoglobin complex will then be removed by the reticuloendothelial system (mostly the spleen). In...
