What are the physical properties of hemoglobin?

Hemoglobin forms an unstable reversible bond with oxygen. In the oxygenated state, it is called oxyhemoglobin and is bright red; in the reduced state, it is purplish blue.

What are characteristics and functions of hemoglobin?

Hemoglobin functions by binding and transporting oxygen from the capillaries in the lungs to all of the tissues in the body. It also plays a role in the transport of carbon dioxide from the tissues of the body back to the lungs. 1. Nitric oxide and carbon monoxide can also bind with hemoglobin.

What are the physical and chemical properties of blood?

Blood consists of cellular material (99\% red blood cells, with white blood cells and platelets making up the remainder), water, amino acids, proteins, carbohydrates, lipids, hormones, vitamins, electrolytes, dissolved gasses, and cellular wastes. Each red blood cell is about one-third hemoglobin, by volume.

What is the chemical formula of Haemoglobin?

The molecular formula of haemoglobin is \[{C_{2952}}{H_{4664}}{N_{812}}{O_{832}}{S_8}F{e_4}\]. Additional information: The common types of normal haemoglobin are Haemoglobin \[A\], Haemoglobin \[F\], Haemoglobin \[A2\]. Haemoglobin \[A\] is found normally in adults.

What are the chemical properties of hemoglobin?

The hemoglobin molecule contains four separate folded peptide chains, which form a hydrophobic or water ‘repelling’ pocket around a heme group. The heme group is composed of a central iron atom complexed to four nitrogen atoms. Oxygen is capable of reversibly binding to the heme unit in a process known as oxygenation.

What are the three functions of hemoglobin?

In light of the information present in the literature the following possible physiological roles of hemoglobin are discussed: (1) hemoglobin as molecular heat transducer through its oxygenation-deoxygenation cycle, (2) hemoglobin as modulator of erythrocyte metabolism, (3) hemoglobin oxidation as an onset of …

What is the physical characteristics of blood?

In humans, blood is an opaque red fluid, freely flowing but denser and more viscous than water. The characteristic colour is imparted by hemoglobin, a unique iron-containing protein. Hemoglobin brightens in colour when saturated with oxygen (oxyhemoglobin) and darkens when oxygen is removed (deoxyhemoglobin).

What are the chemical properties of blood?

About 55\% of blood is blood plasma, a straw-colored liquid matrix in which blood cells are suspended. It is an aqueous solution containing about 90\% water, 8\% soluble blood plasma proteins, 1\% electrolytes, and 1\% elements in transit. One percent of the plasma is salt, which helps with pH.

How is hemoglobin made in the body?

Hemoglobin (Hb) is synthesized in a complex series of steps. The heme part is synthesized in a series of steps in the mitochondria and the cytosol of immature red blood cells, while the globin protein parts are synthesized by ribosomes in the cytosol.

What are the 3 forms of hemoglobin?

The most common are:

• Hemoglobin S. This type of hemoglobin is present in sickle cell disease.
• Hemoglobin C. This type of hemoglobin does not carry oxygen well.
• Hemoglobin E. This type of hemoglobin is found in people of Southeast Asian descent.
• Hemoglobin D.
