WebHemoglobin is a remarkable molecular machine that uses motion and small structural changes to regulate its action. Oxygen binding at the four heme sites in hemoglobin does not happen simultaneously. Once the first heme binds oxygen, it introduces small changes in the structure of the corresponding protein chain. Hemoglobin variants are different types of hemoglobin molecules, by different combinations of its subunits and/or mutations thereof. Hemoglobin variants are a part of the normal embryonic and fetal development. They may also be pathologic mutant forms of hemoglobin in a population, caused by variations in genetics. Some well-known hemoglobin variants, such as sickle-cell anemia, a…

WebHemoglobin S arises as a result of a point mutation (A–T) in the sixth codon of the β-globin gene on chromosome 11, which causes a single amino acid substitution (glutamic acid to valine at position 6 of the β-globin chain). Hemoglobin S is more positively charged than Hb A and hence has a different electrophoretic mobility.
