What is a hemoglobin classified as?

What is a hemoglobin classified as?

Hemoglobin, in the normal adult, is a protein whose main function is to transport oxygen from the lungs to tissues and to transport carbon dioxide from tissues to the lung. The hemoglobin molecule contains four separate folded peptide chains, which form a hydrophobic or water ‘repelling’ pocket around a heme group.

What group does hemoglobin belong to?

The heme group (a component of the hemoglobin protein) is a metal complex, with iron as the central metal atom that can bind or release molecular oxygen. Both the hemoglobin protein and the heme group undergo conformational changes upon oxygenation and deoxygenation.

Is hemoglobin a compound or mixture?

At a simple level, we can say that hemoglobin (a.k.a. haemoglobin) is a metalloprotein. Its molecular mass is about 64000 , which gives you some idea as to the complexity of the molecule. One molecule of hemoglobin contains 4 heme groups, each of which contains a single atom of iron.

Is hemoglobin A transport protein?

Hemoglobin is the protein that transports oxygen (O2) in human blood from the lungs to the tissues of the body. Proteins are formed by the linking of amino acids into polypeptide chains.

What are the two main components of hemoglobin?

Hemoglobin is a molecule inside the red blood cells of human blood. It has two parts: the heme and the globin. The heme contains iron and transports oxygen from the lungs to the tissues as well as takes carbon dioxide from the tissues to the lungs.

What are the two conformations of hemoglobin?

Hemoglobin exists in two distinct conformational states: the T-state (tense) and the R-state (relaxed). The T state has a less of an affinity for oxygen than the R state. The T-state is the deoxy form of hemoglobin (meaning that it lacks an oxygen species) and is also known as “deoxyhemoglobin”.

What are normal hemoglobin types?

The most common types of normal hemoglobin are:

• Hemoglobin A. This is the most common type of hemoglobin found normally in adults.
• Hemoglobin F (fetal hemoglobin). This type is normally found in fetuses and newborn babies.
• Hemoglobin A2. This is a normal type of hemoglobin found in small amounts in adults.

What is the main component of hemoglobin?

Hemoglobin is the most important component of red blood cells. It is composed of a protein called heme, which binds oxygen. In the lungs, oxygen is exchanged for carbon dioxide.

What are the different types of organic compounds?

These are carbohydrates, lipids, proteins, and nucleic acids. In addition, there are other organic compounds that may be found in or produced by some organisms. All organic compounds contain carbon, usually bonded to hydrogen. Other elements may also be present.

How are hydrogens classified in an organic molecule?

Moving on to their classification in detail: Organic compounds are seen in a number of formats, including Lewis structures, space filled models and structural formulas. It is not uncommon to view the hydrogens as lines or to leave them all together in a structural formula of an organic molecule.

Are there any homologous series in organic chemistry?

There are a number of homologous series in organic chemistry such as alkanes, alkenes, alkynes, haloalkanes, alkanols, amines etc. This article deals with the classification of organic compounds.

How are the atoms of an organic compound bonded?

All consist of a central carbon atom to which the following are bonded: 1 a hydrogen atom 2 an alkaline (basic) amino group NH 2 (see Table 2.1) 3 an acidic carboxyl group COOH (see Table 2.1) 4 a variable group
