The alignment of the 141 residues of the alpha chain as well as the 146 of the beta chain were obtained by classical method of sequence analysis and are compared with some mammalian, avian, amphibian, and fish hemoglobin chains. Furthermore, from these sequences, it is possible to explain ...

Hemoglobin Lepore is an unusual hemoglobin molecule composed of two alpha chains and two delta–beta chains as a result of a fusion gene of delta and betagenes. The delta–beta chains have the first 87 amino acids of the delta chain and 32 amino acids of the beta chain. ▪ Individuals ...
The protein in the red blood cells of vertebrates that carries oxygen from the lungs to tissues and that consists of four polypeptide subunits, each of which is bound to an iron-containing heme molecule. [Ultimately short forhematinoglobulin:hematin+globulin.] ...

common hemoblobin types are alpha and beta hemoglobin, while delta and gamma hemoglobin are less common. Hemoglobin contains 4 types of polypeptide chains. There are two polypeptide chains (known as alpha globin chains) that contain 141 amino acid residues. ...
The meaning of HEMOGLOBIN is an iron-containing respiratory pigment of vertebrate red blood cells that consists of a globin composed of four subunits each of which is linked to a heme molecule, that functions in oxygen transport to the tissues after conv
The alpha-2 (HBA2) and alpha-1 (HBA1) coding sequences are identical. These genes differ slightly over the 5' untranslated regions and the introns, but they differ significantly over the 3' untranslated regions. Two alpha chains plus two beta chains constitute HbA, which in norm...
Hemoglobin is a tetramer with four polypeptide chains-two alpha (α) and two beta (β) chains. Each of the polypeptide chains has a heme prosthetic group and an iron atom. The heme group contains a red pigment called porphyrin. Iron attaches itself to porphyrin. When iron binds to oxygen,...
Heterotetramer of two alpha chains and two beta chains in adult hemoglobin A (HbA); two alpha chains and two delta chains in adult hemoglobin A2 (HbA2); two alpha chains and two epsilon chains in early embryonic hemoglobin Gower-2; two alpha chains and two gamma chains in fetal hemoglobin...
