Hemoglobin, iron-containing protein in the blood of many animals that transports oxygen to the tissues. Hemoglobin forms an unstable reversible bond with oxygen. In the oxygenated state, it is called oxyhemoglobin and is bright red; in the reduced state,
The meaning of HEMOGLOBIN is an iron-containing respiratory pigment of vertebrate red blood cells that consists of a globin composed of four subunits each of which is linked to a heme molecule, that functions in oxygen transport to the tissues after conv
Hemoglobin is the oxygen-carrying pigment that gives blood its red color and is also the predominant protein in red blood cells. About 90% of hemoglobin is hemoglobin A (the "A" stands for adult type). Although one chemical component accounts for 92% of hemoglobin A, approximately 8% of ...
(0)-thalassemia, also known as homozygous alpha thalassemia. Due to the complete absence of alpha chains, the predominant fetal hemoglobin is a tetramer of gamma-chains (Bart hemoglobin) that has essentially no oxygen carrying capacity. This causes oxygen starvation in the fetal tissues leading to...
A high hemoglobin count is associated with high hemoglobin levels, which means that your hemoglobin has an increased oxygen-carrying capacity than normal. A high hemoglobin level may indicate: Lung disease;Heart disease;Polycythemia vera;Kidney tumors Dehydration;Hypoxia;Carbon monoxide exposure;High alti...
Hemoglobin (Hb) is an important oxygen-carrying protein, which is composed of two α-chains and two β-chains in humans. Each of these four subunits contains a heme prosthetic group with a central Fe 2 + ion (Coates and Decker, 2017). Recent studies have found that Hb not only works ...
b) administering the oxygen-carrying protein-substantially non-antigenic polymer conjugate to a mammal in need of the oxygen-carrying protein. Preferred oxygen-carrying proteins include recombinantly prepared hemoglobins and preferred non-antigenic polymers include polyethylene glycol....
Hemoglobin (abbreviated Hgb or Hb) is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hgb is made up of four protein molecules (globulin chains) that are connected. The normal ...
(redirected from hemoglobin-oxygen dissociation curve)Also found in: Dictionary, Thesaurus, Encyclopedia. hemoglobin [he´mo-glo″bin] the main functional constituent of the red blood cell, serving as the oxygen-carrying protein; it is a type of hemoprotein in which each molecule is a ...
If one, two, or three heme groups are bound to oxygen, the hemoglobin is partially saturated. The hemoglobin-oxygen combination is called oxyhemoglobin, while hemoglobin that has released its oxygen molecules is referred to as either reduced hemoglobin or deoxyhemoglobin. The binding strength of ...
