An Essay on Hemoglobin Structure and Function: Hemoglobin is the protein that carries oxygen from the lungs to the tissues and carries carbon dioxide from the tissues back to the lungs. In order to function most efficiently, hemoglobin needs to bind to oxygen tightly in the oxygen-rich atmosphere of the lungs and be able to release oxygen rapidly in the relatively oxygen-poor environment of.
Mutations and changes in haemoglobin result in several blood related diseases like sickle cell anemia, a disease where the structure of the cell gets distorted and do not have the capacity to carry much oxygen in the required manner like a normal blood cell would.
Hemoglobin is a two-way respiratory carrier, transporting oxygen from the lungs to the tissues and facilitating the return transport of carbon dioxide. In the arterial circulation, hemoglobin has a high affinity for oxygen and a low affinity for carbon dioxide, organic phosphates, and hydrogen and chloride ions.
Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure. Heme, which accounts for only 4 percent of the weight of the molecule, is composed of a ringlike organic compound known as a porphyrin to which an iron atom is attached.
Structure of Hemoglobin Heme is an iron porphyrin compound. Porphyrin is a tetrapyrrole structure. Ferrous iron occupies the center of the porphyrin ring and establishes linkages with all the four nitrogens of all the pyrrole rings.
Compare the Structure and Function of Collagen and Haemoglobin Essay. Haemoglobin is a conveyance protein that carries O from the lungs to the tissues and carries C dioxide from the tissues back to the lungs. In order to work most expeditiously.
I will be comparing the structure and function of haemoglobin with the structure and function of collagen, which is a structural protein. Collagen’s functions are quite different from those of globular proteins such as enzymes; tough bundles of collagen called collagen fibers are a major component of the extracellular matrix that supports most tissues and gives cells structure from the outside.

Red blood cells are the main type of blood cell in the blood plasma, they are also called erythrocytes and have oxygen carrying properties. They pick up oxygen and release carbon dioxide at the lungs where the capillaries and alveoli’s are in very close contact, the carbon dioxide diffuses from the capillary membrane into the alveoli membrane while the oxygen diffuses in the opposite direction.
Free Essays; Function and Structure of Hemoglobin and Myoglobin Essay; Published by admin at. Categories. Free Essays; Tags. Myoglobin consist of single polypeptide chain that made up of 153 amino acid and ahs a size of 18 kDa. Its three-dimensional structure was first determined by X-ray crystallography by John Kendrew in 1957. Myoglobin is.
Hemoglobin and myoglobin are two of the most important proteins in the body. They are a great example of the old biology maxim, structure equals function, and they show just how important proteins are to organisms. Their functions vary slightly, but they are vital for oxygen transport. The Heme Group. The heme portion of myoglobin and hemoglobin is extremely important because it aids in.
In contrast to hemoglobin, there is only one form of myoglobin. That is, the structure of myoglobin is the same whether oxygen is present or not. The origin of the two different forms of hemoglobin, which account for its cooperative oxygen binding, is the fact that hemoglobin has four subunits.
