Hemoglobin is a globular protein made up of four subunits, each of which contains a polypeptide chain called globin and a heme group. Each hemoglobin molecule is composed of two types of globins organized into four subunits.The two sets of globin chains have minute differences in the sequence and types of amino acids comprising them. This amino acid sequence of a protein is called the primary structure.ach hemoglobin molecule is composed of two types of globins organized into four subunits.

Hemoglobin is a protein inside red blood cells that carries oxygen throughout the body. A hemoglobin test reveals how much hemoglobin is in a person's blood, helping to diagnose and monitor anemia and polycythemia vera.escription. Hemoglobin is made of heme, an iron compound, and globin, a protein. The iron gives blood its red color. Hemoglobin tests make use of this red color. A chemical is added to a sample of blood to make the red blood cells burst.
