Proteins is an important nutrient in the human body, it is made of basic and non-essential amino acids. Protein is important and necessary in the composition and functions of each cell of the living body in humans, animals and plants, and even necessary for viruses.
Plants make proteins from soil and air. Humans and animals take protein from the foods they feed.
Proteins are of great importance because they contain vital amino acids that are beneficial for growth and health of the body. It is the most suitable food for building tissues, which is essential in the formation of muscles in the body. Proteins are the most effective part of burning calories in the body. They are important for building skin and bones and keeping them healthy. Proteins are an important component of the human being, and the other two components are carbohydrates and fats. Protein contains carbon, nitrogen, hydrogen and oxygen, and contains some iron and phosphorus. The proteins have two sources: an animal source and a vegetable source.
Animal protein is found in meat, poultry and seafood such as fish, eggs and dairy products, including milk, cheese and yoghurt.
Vegetable protein is found in: grains such as wheat, rice, maize, legumes such as beans, lentils, white beans and others.
The best source of protein is cheese, fish, meat and milk. These proteins are called “whole proteins”. Because it contains sufficient amounts of all essential amino acids, which contribute to the manufacture of new proteins in the body.
Incomplete proteins are proteins that lack one or more amino acids and are found in grains, legumes, nuts, vegetables and fruits. The nutrients in the fruit are essential because they maintain healthy skin and healthy hair in the body. Which can be eaten whether it is fruit or juices.
The proteins are types :
- Simple proteins: which are found in eggs and corn oil, are hydrolyzed and the proportion of amino acids in them is good.
- Compound proteins: a combination of a nutrient or inorganic molecules with proteins.
- Proteins derived by heat dissolution of the protein, and are divided into derivatives containing amino acids.
The Importance of Proteins:
- Proteins contribute to building hormones.
- Proteins renew cells.
Benefits of proteins:
- Composition of red blood cells.
- The formation of hormones secreted by the thyroid glands, insulin hormones and the formation of enzymes.
- Protein works to build new bone tissues, renewing worn tissues.
- Helps proteins digestion.
- Protein is a source of calories.
The lack of protein in the body in young people causes the weakness of the process of growth, and lack of it in adults can cause loss of hair or muscle size.
Symptoms of the lack of proteins in the body: lack of energy in the body and feeling tired.
If the body contains excess amounts of protein, it will be stored in the form of fat, although the proportion of more in the body will lead to fragility in the bones and form stones in the kidneys.
