Description

Hexapeptide-99 is a chemical compound, a synthetic protein composed of amino acids joined together including:
histidine, leucine, proline, serine, threonine and valine.
It is an abbreviated class of biomolecules and produced by chemical or enzymatic hydrolysis.

Synthetic peptides can be generated as copies of protein fragments by incorporating non-proteinogenic amino acids and modifications to enhance the proteolytic stability of the molecules. Peptides are used in the development of therapeutic drugs for their antimicrobial activity, and for their bioactive interest.
