Melittin is the main active ingredient in bee venom, accounting for about 40-60% of its dry weight. It is a short-chain amphipathic peptide composed of 26 amino acids, and its secondary structure is an alpha helical structure.
This substance has good biological activity and has hydrophobic and hydrophilic regions, which enable it to enter and destroy cell membranes.
Melittin is the cause of pain and inflammation caused by bee stings. In addition, it also has some potential pharmacological properties.
