You need to know the process of protein metabolism at this time. There are various processes in protein metabolism that take place every day. Various stages of protein metabolism will take place with important phases.

Protein metabolism will take place when food starts to enter the stomach. Later the metabolic stage will take place from the stomach to the intestines.
The Process of Protein Metabolism When Food Enters the Stomach
Proteins are macromolecules consisting of chains of amino acids. They play an important role in the structure, function and regulation of the human body. Protein contributes to tissue growth and repair, the immune system, enzymes, hormones, transport of substances, and maintaining fluid balance.
Protein metabolism is the set of biochemical processes that occur in the body to regulate the production, breakdown and use of proteins. Protein is one type of macro-nutrient that is important for the human body. Protein metabolism occurs in various tissues and organs in the body, such as muscles, liver, kidneys and intestines.
Meat, fish, eggs, dairy products, nuts, tofu, tempeh, seeds, and processed meats are examples of foods that contain protein. They provide essential amino acids for growth, tissue repair, and other bodily functions.
Protein-rich food choices allow you to meet your daily protein needs and maintain your body’s health and nutritional balance.
In protein there are approximately 20 different types of amino acids and form long chains. The various types of amino acids also have their own specifications according to their structure.
If the stages of protein metabolism in the body are disrupted, it can affect the body with diseases that can come to attack.
Stages of Protein Metabolism Entering the Stomach
The process of protein metabolism will have various stages that take place. Similar to other metabolisms that occur in the body, protein will occur through two phases.
Yes, protein metabolism that occurs in the body will pass through two phases, namely anabolism and catabolism. Anabolism phase is a process of changing amino acids into protein.
While the catabolism phase is a process of protein breaking down into amino acids. In the stages of metabolism, proteins will connect the two phases of the process.
So that the body can produce energy and repair cells that have been damaged. The stages of protein metabolism will begin when food enters the stomach.

When food enters the stomach, an enzyme called pepsin breaks the peptide bond on the NH2 side. Pepsin enzyme will break aromatic amino acids, decarboxylase, and aromatic amino acids to digest protein. In this process will require an ideal pH.
So that the breaking of peptide bonds can only occur in the stomach with an acidic environment. Enzymes that can break protein bonds will not work if food has reached the large intestine. This is because the large intestine has a high pH.
Stages of Metabolism in the Small Intestine
After the process of breaking the peptide bonds in the stomach, further processes will occur in the small intestine. The process of protein metabolism will take place in the small intestine when it has passed through the stomach or stomach.
In the small intestine, the pancreas will secrete trypsin, carboxypeptidase, and chymotrypsin. The pancreas will break down the protein groups into medium and small chain peptides.
Peptidases in the small intestine perform hydrolysis of medium and small chain peptides which then form free amino acids and tripeptides. Later, the end product of protein metabolism will be absorbed and used by cells. So that later the body can feel the benefits to support health.
Amino Acids Result of Protein Metabolism
From various stages, this protein metabolism will produce amino acids that are beneficial for body health. There are approximately 75 to 80% amino acids from the results of protein metabolism.
The results of these amino acids will be used again to make new proteins. Later, with the Krebs cycle there will be amino acids that will be absorbed by the body.
In addition, there are also some amino acids that will be converted into water, carbon dioxide gas and ATP. The body will not store excess amino acids.

Well, the remaining amino acids will undergo catabolism and change to form urea for amphibolic chemicals. Later, these amphibolic chemicals will leave the body through the urine.
The process of protein metabolism is very important to maintain nitrogen balance in the body and ensure the availability of sufficient amino acids for various body functions. Disturbances in protein metabolism can cause various health problems, such as growth retardation, protein deficiency, or certain metabolic diseases. (R10/HR-Online)
