Hemoglobin (Haemoglobin in many varieties of English) is a tetramer consisting of two dimers that binds to oxygen. Hemoglobin is the oxygen binding protein of red blood cells and is a globular protein with quaternary structure.Hemoglobin consists of four polypeptide subunits; 2 alpha chains and two beta chains. Hemoglobin transports oxygen in the blood from the lungs to the rest of the body.The three-dimensional structure of hemoglobin was solved using X-ray crystallography in 1959 by Max Perutz.emoglobin consists of four polypeptide subunits; 2 alpha chains and two beta chains.

A hemoglobin abnormality is a variant form of hemoglobin that is often inherited and may cause a blood disorder (hemoglobinopathy). Hemoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body. It is made up of heme, which is the iron-containing portion, and globin chains, which are proteins. The globin protein consists of chains of amino acids, the building blocks of proteins. There are several different types of globin chains, named alpha, beta, delta, and gamma. Normal hemoglobin types include:
