Adenosine triphosphate

There are several types of molecules , one of them is known by the name of adenosine triphosphate . This is an organic molecule which means that it has carbon atoms which are linked to hydrogen atoms. It has a series of links with high energy levels and also plays a vitally important role in the metabolism process because it is responsible for carrying out the transport of all the energy necessary to keep the processes of the cells working properly. adequate.

What is adenosine triphosphate?

Adenosine triphosphate is a type of organic molecule that is composed of an adenine ring , a ribose ring and three phosphate groups and is responsible for the chemical reactions that need energy to be carried out quickly.

Characteristics of adenosine triphosphate

Among the main characteristics that can be found in adenosine triphosphate, the following are mentioned:

  • It is known in the field of science as ” energy currency “ .
  • Its bonds are full of energy, although with the naked eye it can be seen as a very simple and small molecule .
  • It can be obtained by means of oxidative phosphorylation and by substrate phosphorylation . The oxidative phosphorylation process involves the oxidation of a series of nutrients through two phases, while substrate phosphorylation does not require oxygen molecules to obtain adenosine triphosphate.
  • It has a cycle that occurs continuously in terms of its use and synthesis for this reason, it is never stored.
  • Its abbreviation is the word ATP .
  • It was discovered by Karl Lohmann in 1929.
  • It is composed of adenosine and three phosphate groups .
  • Regarding its molecular formula, this is: C10H16N5O13P3 .
  • Its molecular mass is 507.181 g / mol.
  • It has an acidity of 6.5.
  • It is unstable and can also be hydrolyzed in water.

Properties of adenosine triphosphate

Among its main properties it is worth mentioning that adenosine triphosphate is a very soluble molecule when it is in contact with water and it does so through a chemical process known as hydrolysis . When it dissolves, it has the ability to release large amounts of energy.

It has the ability to be synthesized continuously and this is done from the glucose obtained from food. It cannot be stored in the natural state, only as a part of other larger compounds. It also has the ability to be stored as animal fat through the synthesis of fatty acids.

Its reserves within the body only last a few seconds because despite being produced continuously, it is also needed by the body. When this process is blocked by some substance, death would happen almost immediately. It cannot be stored naturally , only through intermediaries that participate in the molecule’s production chain.

Another important aspect is that adenosine triphosphate can never be stored since the molecule is in a cycle that occurs continuously in terms of its use and synthesis. This is the way in which a good balance can be formed between the adenosine triphosphate that has been formed and the product that has been hydrolyzed, in other words the ADP.

Structure

The structure of adenosine triphosphate is a nucleotide that has three phosphates, two pyrophosphate bonds and is composed of several elements including:

  • Adenine that forms the nitrogenous base of the molecule and that also has nitrogen within its structure. It is possible to find DNA and RNA .
  • Ribose that is located in the center of the molecule. This is a type of pentose sugar since it has five carbon atoms.
  • Phosphate radicals that in total are three, two of which have bonds with high energy levels.

Chemical formula

The chemical formula that can be found in the molecule of adenosine triphosphate is C10H16N5O13P3 .

Function

Adenosine triphosphate has several functions of great importance for life, mainly for metabolism , a process carried out by all living beings. It has the ability to make energy costs but at the same time to replace them efficiently, quickly and continuously so that the process can continue. It is also in charge of being able to provide the necessary energy to carry out various biological processes .

It is also responsible for acting as a type of signaling molecule in all the processes that occur within the cell and for this reason, it is necessary so that the components of DNA and RNA can be synthesized correctly. It is also part of the transfer of substances between membranes. It is then in charge of the transport of the molecules through the membranes , of synthesizing the compounds that enter the organism and of carrying out all the mechanical work .

It also participates in the process of synthesis of proteins which are made up of amino acids. It supplies all the energy that is needed to be able to carry out work related to movement and locomotion , as these are part of mechanical work, one of its main functions.

Synthesis

The synthesis of adenosine triphosphate is carried out through hydrolysis, which is a type of reaction that causes the molecule to break down when it comes into contact with water . This synthesis can be represented by the following formula:

ATP + Water ⇋ ADP + Pi + energy

In which Pi refers to the inorganic phosphate group , ADP to adenosine triphosphate . This process implies that large amounts of energy are released. All this energy that arises from the synthesis of adenosine triphosphate is then used in a series of reactions used in the metabolic processes carried out by cells since most of them will need energy to function.

Importance of adenosine triphosphate

The main importance of adenosine triphosphate is that it is the main source of energy through which all cell functions can be carried out, including the synthesis of large molecules such as DNA and RNA . In addition, it plays a vital role in the proper transport of macromolecules in cell membranes, in other words, it directly intervenes in exocytosis and endocytosis , processes necessary for life.

It is also responsible for all the maintenance related to the structure of the cell, the contraction of muscles and the processes related to all the energy needs of living beings, mainly those related to locomotion and respiration .
