Over 95% of typical adult hemoglobin is made up of two alpha (α) and two beta (β) globin protein chains. Each α and β chain can bind an oxygen molecule from your lungs and deliver it to ...

Adult hemoglobin, expressed primarily after birth, contains four protein subunits -- two beta-globin and two alpha-globin. Mutations in the beta-globin gene cause sickle cell disease and beta ...

Most healthy hemoglobin includes two proteins: alpha-globin and two beta-globin. Inheriting faulty alpha-globin genes causes alpha-thalassemia.

Quantitative data from a variety of taxa indicate that the two α-globin loci produce subunits in unequal amounts, usually in a ratio near 2:1. The reason for such a remarkable evolutionary ...
