Hemoglobin is a protein molecule found in red blood cells (erythrocytes) that carries oxygen from the lungs to the rest of the body. Without hemoglobin, your red blood cells cannot deliver the oxygen that your cells need to produce energy. Hemoglobin is vital for human life. Hemoglobin is a...

[ILLUSTRATION OMITTED] Anemias Anemia is a common blood disorder in which a person's blood has a lower-than-normal number of red blood cells (RBCs) and can occur if the RBCs don't contain enough hemoglobin. Hemoglobin is an iron-binding protein found wit...
Hemoglobin (Hb) is the protein contained in red blood cells that is responsible for delivery of oxygen to the tissues. To ensure adequate tissue oxygenation, a sufficient hemoglobin level must be maintained. The amount of hemoglobin in whole blood is expressed in grams per deciliter (g/dl). ...
Non-enzymatic glycation of protein is a chemical modification reaction often found in human metabolism. Glycated hemoglobin (HbA 1c ) has been used as a model protein for studying non-enzymatic glycation because of its biological significance. Several questions have been raised in the course of stu...
Hemoglobin is a protein tetramer that consists of 4 heme groups and 2 pairs of polypeptide chains translated from 2 globin genes. In adults, the greatest concentration of the hemoglobin molecule (Hb AA) consists of 2 α chains (HBA gene) and 2 β chains (HBB gene), with one of each of...
One proposita had an abnormal Hb with similar electrophoretic mobility to Hb J Bangkok, but tryptic peptide mapping by h.p.l.c., amino acid analysis and protein sequence analysis revealed an abnormal peptide α-T9, due to the mutation [α61 Lys-Asn], previously found in Hungary and ...
The model is based on that of Szabo and Karplus [Szabo, A., & Karplus, M. (1972) J. Mol. Biol 72, 163--197] but has been extended to include the properties of dissociated dimers in equilibrium with tetramers. The dissociation eliminates the alpha 1 beta 2 intersubunit contact which ...
One of the most striking topological features to be found in a protein is that of a distinct knot formed by the path of the polypeptide backbone. Such knot... AL Mallam,ER Morris,SE Jackson - 《Proceedings of the National Academy of Sciences of the United States of America》 被引量: 84...
Neogenin, an avian cell surface protein expressed during terminal neuronal differentiation, is closely related to the human tumor suppressor molecule delet... Using a monoclonal antibody, we have identified and characterized a previously unknown cell surface protein in chicken that we call neogenin and...
