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
: a protein that contains iron, is the chief means of transporting oxygen in the body of vertebrate animals, occurs in the red blood cells, and is able to combine loosely with oxygen in regions (as the lungs) where it is in high concentration and release it in regions (as the tissues ...
If you have diabetes, a high hemoglobin A1C means that you are more likely to experience complications including: Problems with eyesight Heart disease Stroke Kidney disease Nerve damage The hemoglobin A1c measurement is also important in screening for diabetes. People with an A1C greater than 6% are...
The release (and binding) of oxygen is a cooperative process, which means that the loss (uptake) of the first oxygen molecule triggers the release of the remaining three.The current model for oxygen binding in haemoglobin and myoglobin can be explained in the following way. The deoxy form ...
Hemoglobin is by no means unique to vertebrates; there are a variety of oxygen transport and binding proteins throughout the animal (and plant) kingdom. Other organisms including bacteria, protozoans and fungi all have hemoglobin-like proteins whose known and predicted roles include the reversible ...
In type 2 diabetes, the body's cells cannot take up glucose properly, leading to high levels of glucose in the blood. Insulin resistance means that although the body can produce insulin, the body's cells do not respond properly to the insulin that is made. Over time, the pancreas reduces...
You’ll probably get tested once a year if you have prediabetes, which means you have a strong chance of developing diabetes. You may get tested twice each year if you havetype 2 diabetes, you don't use insulin, and your blood sugar level is usually in your target range. ...
Introduction: Sickle cell disease (SCD) is characterized by deoxygenation-induced polymerization of hemoglobin in red blood cells (RBCs), leading to altered RBC rheology, vaso-occlusion, and hemolytic anemia. The chronic hemolytic anemia, experienced in varying degrees by patients with SCD, reduces ...
For example, the superscript A means that it is hemoglobin A, a normal type of hemoglobin. Sometimes, there may be a superscript number, which is used to designate where along the polypeptide chain an abnormal substitution occurred. So if the superscript 121 was present, this would mean ...
A low hemoglobin count means that the oxygen-carrying capacity of your hemoglobin is reduced. Consult with your doctor if you suspect that your hemoglobin is low. According to the Mayo Clinic, low hemoglobin levels can indicate that an individual has certain medical conditions, including: Aplastic...
