What do proteins contain?

 the components of protein are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

What are the components of protein?

Protein is a highly complex substance found in all living organisms. Proteins are also of good nutritional value. They are involved in the basic chemical processes of life. What are the components of protein?

protein components

The protein molecule is one of the very large molecules in the body, as it consists of many amino acids linked together to form long chains, there are about 20 different types of amino acids that are naturally found in proteins, and proteins with similar function are composed of similar sequences of amino acids this is.

Linked amino acids to each other in the protein molecules by peptide bonds between the amino group of the amino acid group and one carboxylic neighbors of another amino acid, and include amino acids that are the most prominent components of proteins as follows:

  • Glycine, the simplest amino acid.
  • Alanine.
  • Valine.
  • Leucine.
  • Isoleucine.
  • Serine.
  • Cysteine.
  • Aspartic acid.
  • Asparagine.
  • Threonine.
  • Methionine.
  • Glutamic acid.
  • Proline
  • Hydroxyproline.
  • Lysine.
  • Arginine.
  • Histidine.
  • Phenylalanine.
  • Tyrosine.
  • Tryptophan (Tryptophan).

The importance of protein

After we have mentioned the most prominent components of protein, it must now be noted that proteins are of great importance for life and are necessary for the application of a wide range of cellular activities, and these are represented in each of the following:

  • Proteolytic enzymes catalyze the vast majority of chemical reactions that occur in the cell.
  • Proteins provide many of the structural elements of the cell, and help bind cells together in tissues.
  • Antibodies that protect the body from disease are proteins, and many hormones  are also proteins.
  • Proteins control gene activity and regulate gene expression.

protein sources

Protein can help in losing excess weight through a constant feeling of fullness, but it is important to eat the right amount and the right type of protein to get its health benefits. Here are some protein-rich sources:

1. Seafood

Seafood is an excellent source of protein because it’s usually low in fat, but fish, such as salmon, may be slightly higher in fat, but it’s the heart-healthy kind, with omega-3 fatty acids.

2. Milk, cheese and yogurt

Dairy products such as: milk, cheese, and yogurt are not only excellent sources of protein, they also contain calcium, and many are fortified with vitamin D, but it is preferable to choose low-fat or skimmed dairy products to maintain strong bones and teeth and help prevent osteoporosis .

3. eggs

Eggs are one of the least expensive forms of protein, and the American Heart Association recommends that healthy adults eat one egg daily.

4. Beef

Beef is also an excellent source of zinc, iron and vitamin B12.

5. Soy

Eating 50 grams of soy protein per day can help reduce cholesterol by about 3%, and eating plant-based soy protein instead of high-fat protein sources while maintaining a healthy diet can be beneficial for heart health.
