HIV is a virus that causes AIDS. It does not result from abnormal hemoglobin or abnormal hemoglobin levels.
sickle-cell disease
Hemoglobin.
One cause is a defect in the body's systems to reduce methemoglobin to hemoglobin. The other cause is a mutant form of hemoglobin called hemoglobin M that cannot bind to oxygen.
There are many ways in which a low hemoglobin can occur. Among these include young ladies in their menstruating cycle, pregnant women, blood donating frequently, wounds, nosebleeds, Aplastic Anemia, Cirrhosis, Leukemia, etc. Low hemoglobin usually occurs because the body is too slow to produce more red blood cells, but do not be alarmed yet, go to a doctor before anything. Sometimes a low hemoglobin is actually normal for some people.
Anemia is a decrease in the oxygen-carrying ability of the blood. causes decreaes in rbc number inadaquate hemoglobin content in rbc abnormal hemoglobin in rbc.... human anatomy classic
Hemoglobin carries oxygen to the body's tissues. It is found in erythrocytes.
If you mean why isn't a cockroaches blood red, it is because they do not use hemoglobin to carry the oxygen in their blood. Hemoglobin is what causes blood to be red.
The difference in electrophoretic pattern between normal hemoglobin A and hemoglobin S is due to a single amino acid substitution. In hemoglobin S, a glutamic acid is replaced by a valine at position 6 of the beta-globin chain. This change causes hemoglobin S to have a different charge, leading to its characteristic migration pattern on electrophoresis.
The primary factor that determines how much oxygen is actually bound to hemoglobin is the partial pressure of oxygen (pO2) in the hemoglobin solution.
Sickle cell hemoglobin differs from normal hemoglobin due to a mutation in the gene that codes for the hemoglobin protein. This mutation leads to the production of an abnormal hemoglobin variant (HbS) that causes red blood cells to become sickle-shaped, leading to various complications such as blockages in blood vessels and reduced oxygen delivery to tissues.
Less then 1 percent cause disease. Disease causing bacteria produce toxins- powerful chemicals that damage cells and make you ill.
