What is the function of protein and why is this nutrient always recommended in healthy diets? Protein is made up of 20 essential amino acids for the body, a lack of protein can lead to malnutrition, growth retardation, immunodeficiency, negative effects on organs in the body. Below you will learn 9 functions of protein for the body and how to supplement protein accordingly!
* The Functions of Proteins.
1. Functions of proteins Maintains body tissues.
The function of proteins can help in the growth and maintenance of body tissues. The amount of protein in the body is always in a state of constant transformation. This means that normally, your body breaks down the same amount of protein it uses to build and repair tissue.
In other cases, however, the body breaks down more protein than it can make to fulfill the body’s urgent needs. This usually happens during an illness, while pregnant or breastfeeding. Certain groups of people also need more protein, such as people recovering from injury or surgery, the elderly, and athletes.
2. Enhance metabolism.
The structure of enzymes allows them to combine with other molecules inside cells called substrates, which help catalyze reactions necessary for the body’s metabolism.
Enzymes also function outside the cell, such as the digestive enzymes lactase and sucrase that help digest sugars in the stomach. Some enzymes need other molecules such as vitamins or minerals to function.
Functions of enzyme proteins that play a role in bodily functions include:
– Stretch muscles.
– Energy production.
3. Protein function Information transmission factor.
* Protein plays the role of hormones to help transmit information.
Some proteins are hormones, which act as chemicals that aid in communication between cells, tissues, and organs. They are then transported in the blood to target tissues or organs where they bind to protein receptors on the surface of cells.
Proteins and peptides: Made from chains of amino acids, from a few to hundreds.
Steroids: Formed from cholesterol, the sex hormones testosterone and estrogen.
In which, the function of protein and polypeptide accounts for most of the hormone in the body, including:
Insulin: A hormone that signals the uptake of glucose or sugar into cells.
Glucagon: Hormone that signals the breakdown of stored glucose in the liver.
– HGH (human growth hormone): Stimulates the growth of various tissues, including bones.
Protein function can affect the release of hormones that control appetite and food intake. These effects include reducing the “hunger hormone” ghrelin and stimulating the production of the satiety hormones PYY and GLP-1.
4. Build body structure.
Some proteins are fibrous and give strength and elasticity to cells and tissues.
Collagen: The most abundant protein in the body, serving as the structural protein of bones, tendons, ligaments and skin.
Elastin: The function of this protein is several hundred times more flexible than collagen.
5. The function of proteins to help build the immune system.
The function of the protein is to help the body form immunoglobulins or antibodies to fight infection. Antibodies are proteins in the blood that help protect your body from harmful agents such as bacteria and viruses. Without these antibodies, bacteria and viruses would be free to invade, multiply and harm the body with the diseases they cause.
The function of proteins can help the body make antibodies against a particular bacteria or virus, the body will automatically remember how to make antibodies. This allows the antibodies to react quickly when the same bacteria or virus enters the body.
6. Functions of Proteins Maintain proper pH.
Protein plays an important role in regulating acid-base levels in the blood and other body fluids. balance
Acid-base balance is measured on a pH scale that ranges from 0 to 14. Level 0 is the strongest acid, 7 is neutral and 14 is the most alkaline, the body has stomach acid at pH 2 and blood at pH 7.4.
Buffer systems in the body help ensure that the amount of fluid inside the body maintains a normal pH range. Maintaining a stable pH is essential, as even a small change in pH can be harmful or potentially fatal.
The function of proteins helps to regulate pH in the body thanks to hemoglobin (the protein that makes red blood cells) by binding a small amount of acid, which helps to maintain a normal pH value in the blood. Other pH buffer systems in the body include phosphate and bicarbonate.
7. Fluid balance in the body.
Protein functions help regulate body processes to maintain fluid balance.
If you don’t consume enough protein, albumin and globulin levels will drop. As a result, the body cannot keep blood in the blood vessels and fluid is forced into the spaces between the cells. Fluid buildup there causes swelling or edema, especially in the stomach area.
8. Function of Protein Helps Transport Nutrients.
High protein diet helps to bring nutrition to the body
The function of proteins is to help transport substances in the blood into or out of cells. Substances transported by protein include vitamins, minerals, blood sugar, cholesterol, and oxygen.
For example, hemoglobin is a protein that carries oxygen from the lungs to body tissues. Glucose transporter (GLUT) moves glucose to cells. Lipoproteins transport cholesterol and other fats in the blood.
Protein transporters are all specific, which means they will only bind to specific substances. In other words, a protein transporter that moves glucose will not transport cholesterol.
9. Functions of proteins Provide active energy.
The function of protein can help provide calorie energy for the body. Calories come from 3 main sources including:
– 1g of protein contains 4 calories
– 1g of carbohydrates contains 4 calories
– 1g fat contains 9 calories
Of these three main sources, protein is the substance that the body uses for energy eventually. Because the body easily stores, metabolizes carbs and fats more efficiently than protein. Therefore, these two substances play a more efficient role of providing energy.
Normally, protein rarely provides energy for the body. However, in a fasted state (18 hours – 48 hours without food) your body breaks down skeletal muscle so that amino acids can provide energy.
The function of protein to provide energy for the body is often when you are in a state of fasting, exercising, or not consuming enough calories for the body.
Protein supplement through whey protein,You can get protein through foods like milk, eggs, beef, chicken, seafood, or nuts like almonds, walnuts, cashews, peanuts… Besides, you can also steam them. Protein intake through whey protein supplements.
Excessive protein consumption will not bring you body benefits, but also many other health problems. Therefore, you should note that the dosage of protein supplements includes:
Dosage for normal people: Add from 0.8 to 1.3g of protein per 1kg of body weight.
Dosage for bodybuilders: Add about 2g of protein per 1kg of body weight.
Protein consumption needs to be ensured in a safe dose, if you use excessive protein for a long time, it will increase your risk of experiencing conditions such as cardiovascular disease, disorders of the vascular system, liver and kidney damage, disease. diabetes, cancer, osteoporosis…
To receive the functions of protein, you should note that you should not only eat foods containing protein, but build a diet with lots of fiber, vitamins and other nutrients.
The information above can hopefully help you better understand the functions of protein in the body and how to supplement protein accordingly. Protein is important, but it’s not the only substance the body needs, so you should consume enough along with other important nutrients for the body!
