Hemoglobin

fetus draws its oxygen from the mother’s blood where the oxygen content is low. The hemoglobin in adults consist of two alpha and two beta subunits. Fetal hemoglobin consists of two alpha and two gamma subunits. This allows hemoglobin to bind oxygen with higher affinity compared to adult hemoglobin, allowing the extraction of oxygen from maternal circulation. It Is important in fetal development because fetal hemoglobin is the main oxygen transport protein during the last stages of development.…

Sickle Cell Anemia is a trait or disorder that is characterized by abnormal hemoglobin which causes red blood cells to become crescentic or sickle shaped, erythrocytes and by speeding up hemolysis, due to substitution of a single amino acid. Low oxygen tension causes polymerization of the abnormal beta chains which changes the shape of the red blood cells to the sickle form. Sickle cells are fragile and they break apart easily they die leaving you with a poor amount of red blood cells. The red…

Anemia is a condition that occurs when an individual’s blood does not have enough hemoglobin or red blood cells. Hemoglobin is the main foundation of a red blood cell. It helps sustain it by binding it to oxygen. If one does not have enough red blood cells, the cells within one’s body will not receive the sufficient amount of oxygen it needs to function properly. Anemia can be caused by several factors since there are more than a single type of anemic conditions. Therefore these conditions are…

evident in the patients who are heterozygous for the Hemoglobin S allele. The signs and symptoms that are suggestive of sickle cell anemia include acute fever, relative hypertension, jaundice, ulcers, increase in respirations in acute chest syndromes, cough and hyperactive precordium. The patients may also experience joint pains…

complete cell lysis where 100% of erythrocytes have burst, allowing for relative absorbance and percent lysis values to be calculated in contrast to complete lysis. These tubes control for the variance in the amount of cells lysed and the amount of red hemoglobin released from lysed cells, by comparing and contrasting the visual appearance and absorbance values of Test tube 1 and 8 against the…

through the blood stream (“Blood doping”). By increasing your red blood cell count, you increase the amount of oxygen your body is capable of moving to your muscles. A single red blood cell contains about 250 million molecules of hemoglobin and each molecule of hemoglobin binds four oxygen molecules to transport to muscles (Bowers). Naturally, increasing the number of red blood cells increases the total amount of oxygen delivered to cells. When…

In BIS 102, we have discussed about hemoglobin, myoglobin, their structure, and their functionality. However, we have not really related the information into real life situation. Therefore, this paper will illustrate their nutritional aspect and how iron is so important in our daily diet. Myoglobin can be found in blood and its job is to store oxygen until our body needs it. Meanwhile, hemoglobin is also in blood, but its functionality is to transport oxygen through blood vessels from our…

Hemoglobin S is characterized by a “sickle” shaped erythrocyte. These sickle shaped erythrocytes often result from decreased oxygen delivery to the body’s tissues. When oxygen is low in the body the sickle shaped erythrocytes clump together. Clumps of sickle…

Iron deficiency anemia occurs when the body doesn’t have enough iron. Iron is a necessary component of hemoglobin. Red blood cells contain hemoglobin, this substance is extremely important because it carries oxygen from the lungs to the rest of the body. Iron is also essential to preserve healthy cells, hair, skin and nails. At first, iron deficiency anemia can be so mild that it can be unnoticed. As the body becomes more iron deficient and anemia becomes worse, the signs and symptoms…
