Chemical Structure of Human Haemoglobin
UNITY OF LIFE; ESSAY

a) Describe the chemical structure of human haemoglobin (including diagram) b) Over the hundred variant of haemoglobin (caused by genetics mutation) have been describe to date, select one variant found in human (e.g Hb s) discuss the prognosis of named disorder

The major purpose of moving a fluid in the body is provide a mass transportation over a distance where diffusion is inadequate or too slow.(Knut Schmidt-Nielsen, 1997, 5th edition), in term of but the transportation of oxygen and carbon dioxide by diffusion in human is insufficient, this distribution is enabled by a movement of fluid called blood,
In effect human body use one molecule found in the red blood cell called haemoglobin, on the other hand the haemoglobin can be define as a molecule found in the red blood cell which deliver or transport oxygen to the rest of body muscles and tissues.
In this our essay we are going to describe the chemical structure which form the human haemoglobin, so what is really a haemoglobin?
Scientist have conclude that name haemoglobin is a combination of two names Hem and Globins , they continue to define that hem is iron compounded and contain a rise structure while Globin is a red protein the technical abriviation of the haemoglobin is Hb or Hgb, while this protein molecule remain so essential for the human survival tissues it has been proven by scientists that it drawn the oxygen from the lung and transport to different part of body , this has been made possible circulatory system which use three majors organs in the name of Heart, Blood, and Blood Vessel.
According to Cecie Starr and Ralph Taggart (1989) firstly they define the Blood is a fluid as ‘ a fluid connective tissue composed of water, diverse solute, and formed elements. Secondly the Heart as a muscular pump that generates the pressure needed to keep blood flowing throughout the body. Thirdly the Blood vessel as tubes of varying diameter through which

    Proteins have lively and complex structures. The purpose of a protein is decided by its structure; a change in the proteins activity level causes a change in some part of the proteins shape. In the experiment it is clear that the hemoglobin molecules of people with sickle cell anemia traveled at a different rate and therefore ended up at different places on the electrophoresis gel. Hemoglobin is a protein in red blood cells that carries oxygen through the body. Sickle cell hemoglobin is not like normal hemoglobin. It…

    The cardiovascular system is composed of a pump—the heart—and blood vessels that distribute blood containing oxygen and nutrients to every cell of the body. The principles governing blood flow are the same physical laws that apply to the flow of liquid through a system of pipes. For example, one very elementary law in fluid mechanics is that the flow rate of a liquid through a pipe is directly proportional to the difference between the pressures at the two ends of the pipe (the pressure gradient) and inversely proportional to the pipe’s resistance (a measure of the degree to which the pipe hinders or resists the flow of the liquid): Flow pressure gradient/resistance P/R…

    Long before Thomas Jefferson was the third President of the United States of America, the Virginian developed a unique passion for food and wine. Upon his arrival to the soon-to-be United States he found dull colonial cuisine, unappetizing . The common fare was far from elegant and rather boring. Even high society was not accustomed to the elegant meals from accomplished and worldly chefs. Meals typically consisted of boiled, roasted, baked, or stewed meats, served with poorly cooked, overly salted vegetables, a side of bread and a highly sweetened dessert.…

    Candidiasis is an infection caused by Candida fungi, especially Candida Albicans. These fungi are found almost everywhere in the environment. Some may live harmlessly along with the abundant "native" species of bacteria that normally grow the mouth, gastrointestinal tract and vagina. Usually, Candida is kept under control by the native bacteria and by the body's immune defenses. If the native bacteria are decreased by antibiotics or if the person's immune system is weakened by illness (especially AIDS or diabetes), malnutrition, or certain medications, Candida fungi can multiply to cause symptoms. Candida infections can cause occasional symptoms in healthy people. Candidiasis can affect many parts of the body, causing localized infections or larger illness,…

    In people homozygous for hemoglobin S, the presence of long-chain polymers of hemoglobin S distort the shape of the red blood cell from a smooth doughnut-like shape to ragged and full of spikes, making it fragile and susceptible to breaking within capillaries. Carriers have symptoms only if they are deprived of oxygen or while severely dehydrated. The sickle-cell disease occurs when the sixth amino acid, glutamic acid, is replaced by valine to change its structure and function; causing the hemoglobin to collapse on itself occasionally. When enough hemoglobin collapses on itself the red blood cells become…

    Sickle-Cell Anemia

    • 1625 Words
    • 7 Pages

    Sickle-cell disease is a genetic disorder that results from the abnormal structure of red blood cells. The peculiar shape of the red blood cell prevents the normal absorption of oxygen. This disease results from the abnormal production of hemoglobin S (HbS). Therefore, a mutation in this gene causes a lower supply of oxygen to the cells, which results in occlusion of the blood vessels. Individuals diagnosed with sickle-cell anemia have abnormal function of the gene that encodes for subunit B, which is a protein that serves as part of the hemoglobin A (HbA). The HbA is responsible for oxygen binding through the blood stream. Indeed, the abnormal polymerization of hemoglobin occurs in homozygous individuals with sickle-cell anemia, which lowers the oxygen supply of red blood cells. To lower the negative consequences of sickle-cell anemia, it is necessary to provide a better understanding of the genetic material that underlies the sub-phenotype of sickle-cell anemia. Therefore, this could help in the discovery of drugs that could target the genes responsible for sickle-cell anemia.…
