oligopeptides

Oligopeptides are small chains made up of a few amino acids linked together, typically between 2 and 20. Amino acids are the building blocks of proteins, and when they connect in specific sequences, they form oligopeptides. These short chains play important roles in biological processes, such as signaling and immune responses, and can act as hormones or serve as precursors for larger proteins. Because of their size, oligopeptides are often more easily absorbed or recognized by the body, making them useful in medicine, nutrition, and cosmetics.
