| Description | Palmitoyl tetrapeptide-20 (PTP20) is a biomimetic peptide agonist of α-MSH. Palmitoyl tetrapeptide-20 promotes hair pigmentation and delays hair graying by activating the MC1-R pathway (AC50: 0.16 nM), enhancing catalase activity to reduce H2O2 accumulation, and upregulating SIRT1 activity.

Palmitoyl tetrapeptide-20 promotes hair pigmentation and delays hair graying by activating the MC1-R pathway (AC50: 0.16 nM), enhancing catalase activity to reduce H2O2 accumulation, and upregulating SIRT1 activity. Palmitoyl tetrapeptide-20 can be used in research on preventing hair loss and improving hair graying[1]...

According to its metal content, structure and catalytic strategy, Formate dehydrogenase can be divided into two categories, non-metallic and metal-Formate dehydrogenase is an enzyme ubiquitous in prokaryotes and eukaryotes that catalyzes the reversible oxidation of formate to carbon dioxide. According to its metal content, structure and catalytic strategy, Formate dehydrogenase can be divided into two categories, non-metallic and metal-containing, which are often used in biochemical research[1]...
