In order to perform many of its vital functions and activities, the body needs many important nutrients, most notably proteins. It is considered one of the most important elements because it performs many functions, most notably the production of necessary hormones and enzymes such as insulin and thyroid hormones. It also forms red blood cells and thus helps transport oxygen to cells. The different parts of the body, proteins regulate the work of the digestive system and contain a large amount of amino acids that help the growth and strengthening of the body by helping to form its muscles.
Proteins can be obtained by eating many foods such as rice, meat, milk and its derivatives, in addition to whole grains and vegetables, but despite all this, a large percentage of people are ignorant of the types of proteins; Therefore, we will discuss here the most important types.
Types of proteins and their sources
There are many types of proteins, the most important of which are:
- Meat protein: It contains all kinds of amino acids that the body needs.
- Plant proteins: Here it must be noted that each type of plant provides the body with a specific type of amino acid. For example, the protein that wheat gives the body is different from that in corn, beans or rice, and these proteins are characterized by the fact that the body is unable to store them for long periods; Therefore, it must continue to be supplied to the body.
according to installation
- Simple proteins: This type of protein can be hydrolyzed, and it contains a good proportion of amino acids so that it can be obtained by eating eggs, vegetable oil, or corn oil.
- Compound proteins: They are proteins linked to inorganic food elements or molecules, and when exposed to heat, they separate into derivatives, each part of which contains a specific amino acid.
Every kilogram of the body needs one gram of proteins, and this is in the case of the average person, but the athletic body needs more.
Types of amino acids
As for amino acids, they are of two basic types:
- Essential amino acids: They play a key role in the growth of the body and help it to live and continue, most notably leucine, alanine and lysine in addition to phenyl and valine.
- Non-essential amino acids: These acids are essential for the body’s growth naturally, but they do not work on muscle growth, most notably histidine and proline in addition to arginine.
Symptoms of protein deficiency
The lack of proteins in the body is accompanied by the appearance of a group of symptoms and signs, the most prominent of which are:
- Rapid weight loss.
- Tiredness and fatigue in addition to anxiety and tension.
- Weakness of the body’s resistance to disease.
- In addition, children are exposed to many digestive problems, the most important of which is diarrhea.
