A glycophorin is a sialoglycoprotein of the membrane of a red blood cell. It is a membrane-spanning protein and carries sugar molecules. It is heavily glycosylated (60%). Glycophorins are rich in sialic acid, which gives the red blood cells a very hydrophilic-charged coat. This enables them to circulate without adhering to other cells or vessel ...
Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. [3] Red blood cells are the most abundant cell in the blood, accounting for about 40–45% of its volume. Red blood cells are circular ...
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
A:Normal red blood cells are shown flowing freely in a blood vessel on the top of the diagram. The inset image shows a cross-section of a normal red blood cell with normal hemoglobin. B:Demonstrates abnormal, sickled red blood cells blocking blood flow in a blood vessel (vaso-occlusive crisis). The inset image shows a cross-section of a sickle ...
Global distribution of red blood cell abnormalities. Hemoglobin is a protein that transports oxygen in the blood. Genetic differences lead to structural variants in the hemoglobin protein structure. Some variants can cause disease while others have little to no effect.
The Kell antigen system (also known as the Kell–Cellano system) is a human blood group system, that is, a group of antigens on the human red blood cell surface which are important determinants of blood type and are targets for autoimmune or alloimmune diseases which destroy red blood cells.
Hemoglobin electrophoresis is a blood test that can detect different types of hemoglobin. The test can detect hemoglobin S, the form associated with sickle cell disease, as well as other abnormal types of hemoglobin, such as hemoglobin C. It can also be used to investigate thalassemias, which are disorders caused by defective hemoglobin production.
Respiratory acidosis: This condition is characterized by a build up of carbon dioxide in the blood, which leads to a drop in the blood's pH. This occurs when there is an impairment in the gas exchange process, such as respiratory failure. [15] Hypoventilation: This type of condition can result in higher levels of carbaminohemoglobin.
