Peptides are biologically active molecules formed by amino acids connected by peptide bonds, and they play an important role in the fields of life sciences and modern science and technology. As the basic building block of proteins, peptides not only participate in physiological processes such as cell signaling and immune regulation, but also show broad application prospects in industries such as medicine, food and cosmetics.
The chemical structure of peptides determines their unique biological activity. Usually, peptides composed of 2-50 amino acids are called polypeptides, while shorter peptide chains are called oligopeptides. The formation of peptide bonds depends on the dehydration condensation reaction between the carboxyl group of amino acids and the amino group of adjacent амінокислоти, які каталізуються рибосомами в організмі . мала молекулярна маса пептидів дозволяє їм швидко поглинути людським тілом і грати роль, яка є однією з важливих відмінностей між ними та білками .}
In the field of medicine, the application of peptides is particularly prominent. Many drugs, such as insulin and growth hormone releasing peptide, are developed based on the principle of peptides. Peptide drugs have the characteristics of high specificity and low side effects, and can act accurately on targets and reduce damage to healthy cells. In addition, peptides are also widely used У дослідженні та розробці вакцини стимулювання імунної системи людини виробляти захисні антитіла, моделюючи специфічні фрагменти білка збудників .
The food and cosmetics industries have also benefited from the research progress of peptides. Peptide ingredients added to functional foods, such as collagen peptides, help improve skin elasticity and joint health. In skin care products, peptides can promote collagen production, reduce wrinkles, and become an important ingredient in anti-aging products.
With the advancement of biotechnology, the synthesis and application technology of peptides are also constantly innovating. The maturity of solid-phase synthesis makes the production of peptides more efficient, and the application of gene editing technology makes it possible to develop customized peptide drugs. In the future, peptides are expected to play a greater role in precision medicine, agriculture, and environmental захист .
Принципи та застосування пептидів демонструють необмежений потенціал сучасної біотехнології . від базових досліджень до індустріалізації, пептиди поступово змінюють життя людей і стають мостом, що з'єднує науку та здоров'я .
