Various Functions of Protein which are Important for the Body
Protein is an important macro nutrient for the body, as well as carbohydrates and fats. It is recommended to always be on a diet, what is the body's protein function?
The function of protein for the body
There are many functions of protein. Apart from being a nutrient, protein also gives you energy. In addition, the operating system to access the same protein enzymes and hormones.
Here are 7 functions of protein for the body, that you should not neglect.
- Protein Function # 1: the building and maintenance of body tissues
Since the school year, you already know the function of protein as a nutrient for the development and maintenance of body tissues. The amount of protein absorbed by the body for maintenance, according to your state of health.
For example, people are under recovery after surgery and accidents, requiring a higher contribution than the average protein. In addition, larger amounts of protein are needed when you are sick, and for pregnant and nursing women.
- Protein Function # 2: accelerate chemical reactions in the body
The body needs enzymes, which are made up of proteins, to accelerate various biochemical reactions in the body. The function of this protein is managed by a combination of molecules in the cell, called a substrate. In addition, certain enzymes also work with vitamins and minerals.
Some functions in the body, which depend on the function of the digestive enzyme system, energy production, blood clotting and muscle contraction.
- Protein function # 3: Communication between body parts
Apart from enzymes, some proteins are also needed as hormones. Hormones act as messengers between cells, tissues and organs. Hormones are produced and secreted by the endocrine glands and are transported to tissues or organs targeted by the bloodstream.
Hormones are classified into three main categories, namely proteins or peptides, steroids, and amino acid derivatives. Hormone proteins or peptides make up a large portion of the hormones in the body. For example, insulin for glucose absorption, glucagon for the breakdown of glucose in the liver, human growth hormone (hGH) for different tissue growth.
- Protein function # 4: provide body structure
Some proteins also help the cells and body tissues to become strong. Protein plays a role in the structure of the body in the form of keratin, collagen, and elastin. This protein helps to form certain structural frameworks, interconnected.
Keratin on the skin, hair and nails. Collagen protein is the most abundant protein in the body, and supports the structure of healthy bones, tendons, ligaments and skin. Meanwhile, elastin in the uterus, lungs and blood vessels.
- Protein function # 5: boost immunity
Protein also plays a role in the formation of immunoglobulins or antibodies, which work to fight infection. Thus, you can be protected against foreign objects that cause disease, including bacteria and viruses.
While the product antibodies to fight certain bacteria or viruses, the body's cells will still be able to respond quickly if the same bacteria or virus, re-invade any time after. This happens because of being exposed to the body's immunity to disease.
- Protein function # 6: transportation and storage of nutrients
The various nutrients you consume, are spread by carrier proteins in different cells of the body by the bloodstream. Nutrients are transported, including vitamins, minerals, blood sugar, cholesterol, oxygen.
An example is a transport protein that can detect hemoglobin that carries oxygen from the lungs to body tissues. There is also a glucose transporter (GLUT), which carries glucose into the body's cells. Protein carrier, bring nutrition to work, that is his job.
Apart from transportation of nutrients, there are also proteins that store nutrients. For example, ferritin stores iron.
- Protein function # 7: maintain acid and base balance in the body
Various natural remedies, including in the body have a certain level of acidity. acidity is measured using a pH scale, which ranges from 0-14. The smaller the scale of the pH, the more acidic the solution.
For example, the normal pH range for stomach acid is 2. Meanwhile, across from the blood's normal pH is 7.4. changes in the PH scale in body fluids, although small, can be fatal.
protein has become one of the levels of acidity or pH to regulate fluid levels in the body. For example, hemoglobin in the blood also binds acids in small portions, which can maintain the stability of acidity in the blood.What is the minimum protein intake per day?
To optimize bodily functions, you must consume enough protein. intake depends on various factors, including weight. If you already have an ideal body weight, complete consumption of 56-91 grams of protein for men and 46-75 for women.
It should be noted, that number is the number of grams of protein, not the type of food source of protein. To find out the value of grams of protein food, you can check nutrition calculators at various trusted sources.
