7 Types of Protein in the Body and Their Functions

The types of protein in the body are not only diverse, but also have different functions.

Protein is an important nutrient for building and repairing body tissues. This nutrient has a component consisting of a combination of amino acids. The body needs at least 20 types of amino acids to form thousands of different proteins in the body.

7 Types of Protein in the Body and Their Functions

Different Types of Proteins and Their Functions

Each type of protein performs a specific function. The following are the various types of protein in the body and their functions that are important to know:

1. Enzymes

The first type of protein is enzymes. Enzymes play a major role in various chemical reactions that occur in the body. This type of protein is produced by various organs including the liver, pancreas and bile.

The most important function of enzymes is to break down nutrients in food into substances that are easily absorbed by the body. In the process, each digestive enzyme has a different role, namely:

  • Carbohydrase enzyme, functions to break down carbohydrates into sugars
  • Sucrase enzymes, functions to break down sucrose into glucose
  • Lactase enzyme, serves to convert lactose (milk protein) into glucose
  • Lypase enzyme, functions to convert fats into fatty acids
  • Protease enzymes, functions to convert proteins into acids amino

2. Antibodies

White blood cells in the body produce a type of protein, namely antibodies. Antibodies are part of the immune system and function to protect the body to stay healthy. viruses or bacteria. Furthermore, the immune system will fight these antigens so as not to cause disease or infection.

3. Hormones

Hormones are often referred to as messenger proteins or messenger proteins. This type of protein is produced by endocrine glands and flows directly into the blood vessels.

Hormones play an important role in regulating various body functions, such as growth, development, and metabolism. One of the hormones formed from protein is the hormone insulin which regulates blood sugar levels.

However, keep in mind that not all hormones are built from protein. Reproductive hormones, namely testosterone and estrogen, are categorized in the group of steroid hormones which are formed from cholesterol.

4. Structural protein

As the name implies, this type of structural protein functions to build the structure of cells and body tissues. Structural protein types include keratin and collagen.

Keratin is a type of protein that can strengthen the structure of hair and nails. Meanwhile, collagen is useful for increasing bone strength, skin resistance, as well as the most abundant structural protein in the body.

5. Transport proteins

Transport proteins are needed by the body because they function to transport important molecules, including nutrients which include vitamins and minerals. This molecule will be bound by a transport protein and carried through the bloodstream to be distributed to all body tissues.

The most well-known transport protein is hemoglobin, which functions to bind oxygen from the lungs and circulate it throughout the body.

6. Storage proteins

Proteins can also serve as storage media. Ferritin is one type of protein because it plays a role in storing iron reserves. Ferritin protein can be found in the liver, spleen, and spinal cord.

7. Mover protein

Movement protein has a function to support muscle movement. The type of activator protein that is found in many muscle cells is myosin, which plays a major role in muscle contractions in the body.

Keep in mind, although the body can produce various proteins naturally, you also need to fulfill your intake by consuming various high-protein foods, such as chicken breast and beans.

Now, you already know the various types of protein in the body and their respective functions. If the body is deficient in protein, sufferers can experience swelling in the face and stomach, severe hair loss, brittle nails, dry skin, fatigue quickly, and bones break easily.

If you experience signs of protein deficiency, you should get checked yourself to the doctor to find out the exact cause and get the right treatment.
