Knowledge sharing of bioactive peptides

In the era of rapid development of biological science, a variety of new functional bioactive peptides with high-level research value have been found, and their research results have been paid attention to Bioactive peptide is a compound that two or more amino acids are connected by peptide bond It is an intermediate between amino acids and proteins It is the functional segment and structural segment of proteins, and the active gene part of proteins It is called "commander in chief of life"
It is found that the process of protein absorption is mainly in the form of peptide Bioactive peptides are simple in structure, unsaturated, small in molecular weight and easily absorbed by human body For example, in the gastrointestinal tract, proteins can be digested by digestive enzymes, and bioactive peptides can be completely absorbed, thus entering the blood circulation system and being absorbed and utilized by cells Bioactive peptides are characterized by strong activity and diversity, which are widely used in production, life and science fields due to their own advantages
As we all know, protein is an important component of all cells and tissues in human body All the important components of the body need the participation of protein Protein is a complex organic compound Amino acids are the basic units of protein, which are linked into peptide chains by dehydration and condensation Protein is a biological macromolecule composed of one or more polypeptide chains, and many macromolecules form a stable protein complex by combining, so as to play a specific function It can be said that the existence of peptide chain affects the activity of protein in human body and has an important effect on human body   Under the action of digestive enzymes in gastric juice, the protein is hydrolyzed initially and the whole digestion and absorption process is completed in the small intestine About 70g protein enters the digestive system every day, most of which are digested and reabsorbed The human body's need for protein is actually the need for amino acids Only when the amount and type of amino acids absorbed can meet the needs of human body, the body can synthesize its own protein through peptide chain Experiments show that the functions and functions of protein in human body are completed by peptide
Generally speaking, the digestion and absorption of peptide in gastrointestinal tract is better and faster than that of protein and free amino acid The frequency of gastroptosis and abdominal fullness was low Bioactive peptides play a more active role in life than amino acids As a way of protein supplement, for healthy human body, it is mainly to obtain various small molecular peptides and L-amino acids from the protein of diet, and provide synthetic hormones, enzymes and proteins in vivo   For human body, the renewal, metabolism, growth and repair of human cells are inseparable from peptides Especially with the rapid development of modern society, the improvement of people's health consciousness also promotes the progress and development of life science More and more people fall into the sub-health state gradually because of the pressure of work and study If they want to get out of the sub-health state and become a real healthy person, they need daily nutrition balance and timely supplement of amino acids and nutrient elements needed by the human body, so as to keep healthy.
