Peptides are short chains of amino acid monomers linked by peptide (amide) bonds.
The mechanism of the effect of peptides on the body is well studied. The scientists were able to prove that they are able to regulate the processes of cell activity. And also aware of the fact that the speed of aging depends on the level of peptides in it.
A peptide can perform a wide range of functions in the body, depending on which amino acids are involved. Some can regulate hormones, for example, while others can have an antibiotic function. The body is also equipped to break down and reuse these compounds; if a person eats meat, for example, the enzymes in his intestines break down the protein at its amide bonds to create an assortment of peptides that may be digested or excreted, depending on the needs of the body.
