Where did the protein go after it entered the body?
Protein is involved in the formation of all life forms and the material basis of all life. We consume a lot of protein every day, but do you know where the protein goes after it enters the body?
Regardless of the type of protein ingested by the human body, it is first chewed into smaller units by the tearing of the teeth. Although there are many enzymes in the mouth, it does not digest the protein.
The stomach is the first level of protein digestion. Protein digestion is basically the hydrolysis process of proteins. According to the degree of hydrolysis, it can be divided into complete hydrolysis and incomplete hydrolysis. 1. Complete hydrolysis: The hydrolyzate obtained by thorough hydrolysis is a mixture of various amino acids. 2. Partial hydrolysis: The hydrolyzate obtained by incomplete hydrolysis is a peptide fragment of various sizes and a single amino acid. The protein is decomposed into a polypeptide by the action of the enzyme in the stomach; when the polypeptide enters the epithelial cells of the intestinal mucosa, it is immediately hydrolyzed by the peptidase present in the cell into the amino acid, the most basic component of the protein. Amino acids are mainly absorbed in the small intestine. It also needs to be accompanied by sodium through the vehicle, in order to pass the level of the intestinal mucosa into the blood.
After being absorbed in the small intestine, the amino acid enters the liver along the hepatic portal vein. Some amino acids are decomposed or synthesized in the liver; another part of the amino acids continue to be distributed to various tissues and organs with the blood, and they are selected to synthesize various specific tissue proteins. Under normal circumstances, amino acids enter the blood and their output speed is almost equal, so the amino acid content in normal human blood is quite constant. For example, in the case of amino acids, the content of plasma in each 100 ml is 4 to 6 mg, and the content per hectare of blood cells is 6.5 to 9.6 mg. After the protein was eaten, a large amount of amino acids were absorbed, and the amino acid level in the blood temporarily increased. After 6 to 7 hours, the content returned to normal. It indicates that the amino acid metabolism in the body is in a dynamic equilibrium, with blood amino acids as its balance hub, and the liver is an important regulator of blood amino acids. Therefore, the food protein is digested into amino acids and absorbed by the human body, and the antibody uses these amino acids to synthesize its own protein. The body's need for protein is actually a need for amino acids.
In the liver, amino acids undergo catabolism, that is, deamination, which is the process of deamination of amino acids. The nitrogen-containing compounds produced in this process are converted into urea in the liver, and the process of converting nitrogen-free into sugar or fat. Water and carbon dioxide are also produced midway.
Under deamination, the amino acids eventually form useful sugars or fats and useless urea and carbon dioxide. Sugar and fat are absorbed or stored. Carbon dioxide enters the vein and is eventually breathed out by the lungs. Most of the urea is removed by urine, and a small part is eliminated by sweat.
In general: after the protein is finally decomposed into amino acids, part of it forms sugar or fat, part of it enters the bloodstream and reaches the body to synthesize human tissue proteins, and some components become urea and carbon dioxide are excreted.
Our body absorbs and utilizes proteins in a fast and accurate way. Our detection of proteins also requires rapid and accurate quality ELISA reagents for their detection. The technicians of Wuxi Donglin Technology Development Co., Ltd. have been researching, developing and producing high-quality immunoassay reagents for many years. We provide outstanding products to scientists in the life sciences worldwide and become trusted and reliable suppliers to many of the world's leading research institutions and clinical diagnostic companies.
