Common Name(s): Galloyl sh-nonapeptide-3,galloyl sh-nonapeptide-3,phenolic-conjugated or metal-chelating peptide,dual anti-aging active
CAS Number: N/a
DESCRIPTION
What It Does: Provides combined peptide sequence receptor-mediated collagen synthesis with phenolic antioxidant protection or metal cofactor enzyme activation from one molecule.
Why It's Used: Phenolic-peptide conjugation provides dual mechanism: the peptide sequence targets the receptor while the phenolic group independently scavenges radicals or chelates metal cofactors.
How It Works: Peptide receptor binding → kinase signalling → col1a1 upregulation. feruloyl/galloyl phenolic: catechol radical scavenging from h-atom donation; iron/copper coordination providing cofactor delivery for antioxidant enzymes.
Typically Found In: Premium anti-aging,collagen products
