Palmitoyl-KTTKS (Lysine-Threonine-Threonine-Lysine-Serine) was measured in six different anti-wrinkle creams using a mass-spectrometry analytical procedure (8). Given their potential to modulate collagen and melanin homeostasis, topical application of bioactive peptides is primarily used for cosmetic purposes. Their potent biological effects and high potential for synthesis and modification have attracted attention for applications in skin health and appearance. Postsecretory processing generates multiple cathelicidins for enhanced topical antimicrobial defense. Product formulation can greatly influence the stability of the bioactive peptide. CJC-1295 is comprised of 29 amino acids that make GHRH. 1988;238(2):343-346.

HHS Antimicrobial peptides: primeval molecules or future drugs? In three separate, small, double-blind, placebo-controlled studies, daily application of topical PKEK in combination with the skin whitener, sodium ascorbyl phosphate (SAP), for six to eight weeks enhanced the fading of skin pigment spots compared to either agent alone (26). A peptide is a short chain of amino acids that are linked together, and can be thought of as a small protein. 2011;33(6):483-490. Experiments performed in vitro and in animals demonstrate that GHK alone and as a carrier peptide for copper (GHK-Cu) modulate various aspects of the wound-healing process, including chemoattraction of immune cells, angiogenesis, and collagen synthesis (21-24). J Clin Invest. Peptides are a protein component composed of two or more amino acids bonded in a chain and encrypted into the protein molecule.

Antimicrobial peptides are a vital component of the innate immune system of all eukaryotic organisms and many of these peptides have potent antifungal activity. Exp Dermatol. However, the lack of comparable data sets from large cohorts has greatly hindered the development of clinical proteomics. Peptides cover the chemical space between small molecule drugs (with molecular weight up to 500) and biologics (typically with molecular weight above 5,000). Prlntad in Cmat Britain . Abstractα,β-Dehydroamino acids are naturally occur- ring non-coded amino acids, found primarily in peptides.
