What is a Peptide

Peptides are short chains of amino acids that act as signaling molecules in the body. Amino acids are the building blocks of proteins, and peptides represent smaller structures that help transmit biological instructions between cells.

How Peptides Work

Peptides interact with receptors located on cells throughout the body. When a peptide binds to a receptor, it can trigger specific biological responses depending on the signaling pathway involved.

Examples of Peptide Functions

• Hormone signaling
• Immune response regulation
• Skin pigmentation
• Metabolic processes

Melanotan II is an example of a peptide designed to interact with receptors involved in melanin production.
