Nutritional value of peptide

Generally speaking, the digestion and absorption of polypeptide in gastrointestinal tract is better than that of protein and free amino acid, and the speed is faster Moreover, the retention time of polypeptide in gastrointestinal tract is shorter than that of protein, the frequency of gastroptosis and abdominal fullness is lower, the absorption area of small intestine is reduced, and the digestive function is damaged In essence, the nutritional function of polypeptide is the function of protein and L-amino acid Among them, small peptide plays a more active role in the life process than amino acid, and it can synthesize and decompose proteins from the body As a way of protein supplement, for healthy people, it is mainly to obtain a variety of small molecular peptides and L-amino acids from the protein of diet, providing synthetic hormones, enzymes and proteins in vivo The human body is in the state of disease, especially for severe digestive disorders, post-operative or liver cirrhosis, hepatitis, renal failure, tumor chemotherapy and other critical patients The absorption of food protein is seriously restricted and affected, so peptide can not be synthesized in vivo The circulation of protein and amino acid is destroyed, so it is difficult or impossible to supplement nutrition by general diet At this time, it is a rapid and effective way to directly take polypeptide oral liquid to supplement protein A former retired political worker of Wuhan air force was suffering from esophageal cancer He was unable to eat It was also very difficult to intubate and irrigate food Later, he did not eat for many days His children gave him Sanjiu protein peptide oral liquid, 12 tablets a day, and successfully passed through the critical period of his life The experiment shows that the negative oxygen balance still exists until the food is digested and absorbed from the stomach to the intestines For example, the peptide is emptied in the stomach and absorbed in the intestines faster than the protein in the solid food Therefore, the negative oxygen balance disappears faster If the peptide beverage is supplemented during the exercise, the negative oxygen balance will be like this The stage of muscle catabolism will be further shortened and disappeared Because of its absorbability, peptide will be a good nitrogen source for athletes As a restorative beverage during or at the end of sports, peptide products containing hydrolyzed protein have been widely used in athletes' diets in the United States and Japan Wuhan jiushengtang Bioengineering Co., Ltd has applied soybean peptide to beverages and produced "peptide cool" beverages and soybean peptide beverages.
