Acetyl tetrapeptide-5
is used in cosmetic eye formulations to decrease puffiness, eye bags, and dark circles by reducing edema and protecting proteins such as SOD from glycation
Alanine
Ala / A · hydrophobic residue · neutral charge
AOD-9604
is studied as an anti-obesity peptide that can reduce weight gain and increase fat oxidation in obese animal models with generally neutral effects on IGF-1 and glucose metabolism in early human trials
Arginine
Arg / R · basic residue · positive charge
Argireline
is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner
Asparagine
Asn / N · polar residue · neutral charge
Aspartic acid
Asp / D · acidic residue · negative charge
BPC-157
is investigated for accelerating healing of gastrointestinal mucosa, tendons, ligaments, bone, and nervous tissue in preclinical models, with anti-inflammatory and pro-angiogenic effects
Comparison
While KPV is investigated as an anti-inflammatory and barrier-protective agent in skin and mucosal models, reducing pro-inflammatory cytokines and promoting tissue repair684, MOTS-c improves insulin sensitivity, enhances glycolysis, reduces oxidative stress, and shows protective effects in models of metabolic syndrome, aging, and ischemia-reperfusion injury8135146.
While KPV works as the C-terminal Lys-Pro-Val tripeptide fragment of α-MSH, which exerts potent anti-inflammatory effects largely via inhibition of NF-κB signaling and modulation of cytokine expression, with many actions independent of classical melanocortin receptor activation684, MOTS-c is a 16-amino-acid mitochondrial-derived peptide that translocates to the nucleus under metabolic stress and regulates glucose and lipid metabolism largely via activation of AMPK and modulation of mTOR and folate-cycle–linked pathways854140146.

The clearest overlap between KPV and MOTS-c is that both converge around Gene expression modulator. Their typical research and application settings separate fairly clearly: KPV is more often discussed in the realm of Immunology and inflammation, Gastroenterology, and Dermatology and aesthetics, whereas MOTS-c is more often associated with the realm of Metabolic and endocrine and Aging and longevity. Both appear to work through Gene expression modulator, but the functional emphasis still separates, with KPV leaning toward Anti-inflammatory and Immune regulation and MOTS-c leaning toward Mitochondrial function modulation and Metabolic regulation. KPV has a more natural endogenous origin, while MOTS-c is closer to mitochondrial-encoded background and both are still best understood as being in Preclinical development. Their sequence patterns also diverge, with KPV showing protein-mimetic sequence features and MOTS-c showing hydrophobic domain features.
