Protein
Protein is an organic compound, composed of a single chain. It can consist of a series of amino acid chains. These chains bind bonds called peptide ligaments, and protein is one of the compounds that is very important to the health of the human body, because it is one of the basic constituents of tissues and cells Organs, and regulates the body’s various functions such as hormones and enzymes.
The body gets proteins from foods and foods, and when these proteins enter the body, the body’s sufficient amount of protein is converted to proteins that serve it, while proteins that exceed the body’s need are converted into energy sources of the body such as glucose.
Types of proteins
Proteins in nature are divided into two main parts:
According to the source
Proteins by source are divided into two parts:
- Animal proteins These proteins are obtained from animal sources such as chicken, eggs, red meat, and fish. This type of protein is best because it can supply the body with many amino acids.
- Plant proteins This type of protein gets the body from plant foods such as wheat, rice, maize, beans, and this type of protein does not contain important amino acids for the body.
By melting
- Simple proteins and this type of protein dissolves in water, and this type of protein can form amino acids of it well, and this type of protein is available largely in corn oil, and eggs.
- Complex proteins These proteins are usually made up of organic and inorganic parts with protein molecules. These proteins melt by heat, and this protein is broken down into other parts of amino acids.
Protein forms in the human body
- Lipoprotein, a protein that is found in lymph and in the blood, is often associated with fat and fat in the blood, such as cholesterol.
- High-density lipoprotein This protein is very important in the body as it protects the heart from coronary disease, because of the ability of this protein to rid the cells and tissues of cholesterol.
- Low-density lipoprotein (LDPE). The protein in the body transfers triglyceride triglycerides to cells and tissues so cells and tissues produce energy for the body, or store these trigrams in the body in the form of fat.
- This protein is found in the blood of the pregnant woman only. This protein is produced by the fetus in the salivary fluid, and the increase or decrease of this protein in the blood is a sign of the fetus suffering from deformation or defect. If this protein exists in men Or in non-pregnant women at high rates, this is evidence of their suffering from certain diseases of cancer in the liver or testicles or in the ovaries, and these cancers are identified by the response to the treatment through the work of testing the level of this protein.
