This peptide, Pal-Gly-Gln-Pro-Arg-OH, is a synthetic tetrapeptide conjugated with palmitic acid, primarily utilized in biomedical research and cosmetic applications. It plays a key role in modulating biological processes, particularly in promoting collagen synthesis and extracellular matrix production. It is extensively studied for its potential in wound healing, tissue repair, and skin regeneration by influencing cellular growth, fibroblast activity, and migration. Additionally, its anti-inflammatory properties position it as a candidate for treating inflammatory skin conditions and enhancing barrier function. In dermatology, it is investigated for improving skin elasticity, reducing wrinkles, and repairing UV-damaged tissues. Emerging research also explores its use in targeted drug delivery systems to enhance the efficacy and specificity of therapeutic agents in regenerative medicine.
