classification, types of proteins and their function

 

The proteins are classified according to their origin, their composition or their functions. Although they all play an important role in cellular life, each one can fulfill more than one function. These are present in all types of life, not only in humans. Animals and people must incorporate them through their diets to obtain the necessary levels.

Classification of proteins

Proteins can be distinguished according to their provenance or origin.

  • Animal: they come from animals and among them are fish, dairy, eggs, etc.
  • Vegetable: originate in the plant world such as legumes, seeds, fruits, etc.

Another possible classification is according to the way they are composed:

  • Simple or holoproteins: they are only found in the cell nucleus, in this category are located the amino acids
  • Composite or heteroproteins: They contain a non-amino acid component. In this group are lipoproteins, glycoproteins, metalloproteins, hemoproteins.

Types of proteins and their functions

Within the body they meet certain functions that facilitate the correct action of the different organs. In this sense, they can be classified into:

Structural

They are also known by the name of fibrous proteins and they are responsible for the flexibility or rigidity of certain parts of the body. Among the most common are collagen, keratin, fibroin.

Hormonal

Its function is transmit information from one cell to another and they are transported, generally, through the blood after being secreted by the endocrinal glands.

Backup

They are amino acids that are stored in the body to be used when the body needs them for restructuring, in development processes. Also, to avoid an excess of minerals that could cause negative effects.

Enzymes

They are part of the active proteins, that is, they bind to a ligand to function. Enzymes act as catalysts that accelerate metabolic processes of cells.

Defensive

The role of defensive proteins is immune. To do this, antibodies are generated to resist or attack viruses and bacteria that can enter the body.Vegetables

Regulatory

These proteins interact to regulate different cellular processes. Among regulatory proteins are the receivers that control substances that enter cells.

Contractile or motor

The main role is to regulate muscle contractions and the functioning of the heart. In this way, they make it possible to lengthen or shorten the organ in which they act.

Conveyors

They transport minerals from one cell to another and in some cases they are true input and output channels.

Now that you know the importance of protein for your body, plan a proper diet to lead a healthy life.
