Hemoglobin pathway
Web7 nov. 2013 · Background. Haptoglobin was first described by Polonovsky and Jayle in 1938 as a “plasma substance” that binds hemoglobin 1.When red cells are lysed in vivo, free hemoglobin binds to circulating haptoglobin; the hemoglobin-haptoglobin complex is then degraded by the reticuloendothelial system (Fig. 1).By scavenging free … WebAn early phase of heme breakdown, accounting for 20% of bilirubin, is from hemoproteins (heme-containing enzymes) and occurs within 3 days of labeling …
