How many globin chains in hemoglobin
WebThe hemoglobin molecule is made up of four polypeptide chains (Alpha 1, Beta 1, Alpha 2, Beta 2), noncovalently bound to each other.There are four heme-iron complexes.. Each chain holds a heme group containing one Fe++ atom.. The heme-iron complexes are colored red because they give hemoglobin its red color.. Now the heme molecules have … WebStructural hemoglobin variants: Quantitative defects caused by a reduced/imbalanced synthesis of a normal globin chain are referred to as the “Thalassemias”. Qualitative defects caused by the normal synthesis of an abnormal globin chain, often due to single amino acid substitutions in either the alpha or beta globin chains.
