Peptides are made up of chains of amino acids like letters in a word. Due to the vast diversity of sequences and bioactivities created by this chemistry, nature has used them widely in a host of roles.

These include the defense and repair of exposed surfaces, such as the skin, the lungs and the mouth, constituting part of an ancient aspect of immunity found throughout nature. Helix BioMedix, Inc. is using this natural phenomenon to create programs in the areas of pharmaceutical and non-pharmaceutical applications.
