Nonapeptide-1- Summary
- MOTS-c is a mitochondria-derived peptide (MDP) encoded within the mitochondrial genome. It acts as a metabolic regulator, improving insulin sensitivity, enhancing exercise capacity, and counteracting age-related metabolic decline. It is often called a 'mitochondrial hormone.'
- Nonapeptide-1 is a synthetic 9-amino acid peptide that inhibits melanin production by blocking α-MSH (alpha-melanocyte stimulating hormone) receptor binding. Used in cosmetic formulations for skin lightening and evening skin tone, it is particularly effective for UV-induced and hormonal hyperpigmentation.
