Comparison
While GHK-Cu acts as a tissue-remodeling and wound-healing signal, enhancing skin regeneration, angiogenesis, and repair while reducing inflammation and oxidative damage in experimental models31383, LL-37 acts as a broad-spectrum antimicrobial and immunomodulatory peptide involved in host defense and wound repair, but can also promote inflammation and cancer cell proliferation in some contexts5215.
While GHK-Cu works as an endogenous tripeptide, Gly-His-Lys, that chelates Cu²⁺ and modulates gene expression, stimulating collagen, elastin, proteoglycan, and glycosaminoglycan synthesis while exerting antioxidant and anti-inflammatory effects31383, LL-37 is a cationic amphipathic 37-amino-acid cathelicidin peptide generated from hCAP18 that disrupts microbial membranes and modulates innate immunity, including chemotaxis, cytokine induction, and NET formation521586.
GHK-Cu is 3 amino acids long, whereas LL-37 is longer as it has a length of 37 amino acids. GHK-Cu is made up of a sequence of Glycine, Histidine, Lysine. LL-37 is made up of a sequence of Leucine, Leucine, Glycine, Aspartic acid, Phenylalanine, Phenylalanine, Arginine, Lysine, Serine, Lysine, Glutamic acid, Lysine, Isoleucine, Glycine, Lysine, Glutamic acid, Phenylalanine, Lysine, Arginine, Isoleucine, Valine, Glutamine, Arginine, Isoleucine, Lysine, Aspartic acid, Phenylalanine, Leucine, Arginine, Asparagine, Leucine, Valine, Proline, Arginine, Threonine, Glutamic acid, Serine.
