Common Name(s): Gold thioethylamino hyaluronic acid,gold thioethylamino hyaluronic acid,gold-conjugated active,luxury anti-aging metallic bioconjugate
CAS Number: N/a
DESCRIPTION
What It Does: Provides gold nanoparticle anti-inflammatory spr activity alongside the biological activity of the conjugated molecule — ha humectancy or amino acid conditioning — with gold coordination improving tissue targeting.
Why It's Used: Gold bioconjugates combine the luxury positioning and documented anti-inflammatory mechanism of gold nanoparticles with the functional performance of the conjugated biomolecule for premium anti-aging.
How It Works: Gold coordination: thioether or carboxylate groups form stable au-s or au-o coordinate bonds. gold spr anti-inflammatory: electron transfer to protein thiol groups → ikk-β s-aurylation → nf-kb inhibition. conjugated ha/amino acid provides simultaneous humectant or conditioning activity.
Typically Found In: Premium anti-aging,luxury beauty
