A comparison of copper binding properties, copper exchange rate and redox potential between two similar naturally occurring copper-binding peptides GHK and DAHK shows that even though both bind copper in stoichiometry at a ratio of 1:1, the exchange rate of copper between DAHK peptides is very slow, while the exchange rate between GHK peptides is much faster

Your body's natural glutathione production decreases by approximately 10-15% per decade after age 20, while collagen production drops by about 1% annually starting in your mid-20s
For peptide nucleic acids (PNAs), the sugar-phosphate backbone is replaced by a peptide backbone, which retains the specific binding ability with DNA/RNA and offers higher affinity and better stability than natural nucleic acids
