Peptides

Peptides are polymers composed of two or more amino acids linked by peptide bonds, forming short protein chains typically ranging from 2 to 50 amino acids. They are created through a condensation reaction between the amino group of one amino acid and the carboxyl group of another, resulting in a covalent bond. Peptides play crucial roles in various bodily functions, including digestion, energy utilization, hormone regulation, and cell movement. They are biologically active substances that participate in complex physiological activities, influencing hormone, nerve, cell growth, and reproductive functions. Peptides are classified based on the number of amino acids they contain: dipeptides consist of two amino acids, tripeptides of three, and so forth, with chains of up to 50 amino acids being called polypeptides. Peptides are more efficiently absorbed by the body compared to individual amino acids, making them important in nutrition and medicine. In skincare, peptides are valued for their ability to penetrate the skin, providing moisturizing benefits and reducing fine lines and wrinkles.
