Hemoglobins. Eryhem . Ferrous Hemoglobin . Hemoglobin . Hemoglobin, Ferrous . The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements. . 1.00
Fetal Hemoglobin. Hemoglobin, Fetal . Hemoglobin F . The major component of hemoglobin in the fetus. This HEMOGLOBIN has two alpha and two gamma polypeptide subunits in comparison to normal adult hemoglobin, which has two alpha and two beta polypeptide subunits. Fetal hemoglobin concentrations can be elevated (usually above 0.5%) in children and adults affected by LEUKEMIA and several types of ANEMIA. . 0.66
Hemoglobinuria. The presence of free HEMOGLOBIN in the URINE, indicating hemolysis of ERYTHROCYTES within the vascular system. After saturating the hemoglobin-binding proteins (HAPTOGLOBINS), free hemoglobin begins to appear in the urine. . 0.63
Hemoglobin, Sickle. Deoxygenated Sickle Hemoglobin . Deoxyhemoglobin S . Hemoglobin SS . Hemoglobin, Deoxygenated Sickle . SS, Hemoglobin . Sickle Hemoglobin . Sickle Hemoglobin, Deoxygenated . Hemoglobin S . An abnormal hemoglobin resulting from the substitution of valine for glutamic acid at position 6 of the beta chain of the globin moiety. The heterozygous state results in sickle cell trait, the homozygous in sickle cell anemia. . 0.62
