What is the difference between Pal-GHK and TB-500?
Pal-GHK is a palmitoylated form of the GHK tripeptide used in cosmetic-science and fibroblast-culture research (lipopeptide, MW about 578.8 g/mol).
Which is heavier, Pal-GHK or TB-500?
Pal-GHK has a molecular weight of about 578.8 g/mol and TB-500 about 889 g/mol (PubChem), so TB-500 is heavier by 310.2 g/mol, a ratio of 1.54. This means 1 mg of Pal-GHK contains 1,727.7 nmol versus 1,124.9 nmol for TB-500.
How many mg of TB-500 are equimolar to 1 mg of Pal-GHK?
1 mg of Pal-GHK (MW 578.8) is 1,727.7 nmol. The same number of moles of TB-500 (MW 889) weighs 1.536 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Pal-GHK and TB-500
PubChem lists Pal-GHK as C30H54N6O5 (578.8 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). Pal-GHK is a lipopeptide; TB-500 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Pal-GHK equals how many mg of TB-500 in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of TB-500 (MW 889) would weigh 15.359 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of TB-500 equals how many mg of Pal-GHK in moles?
10 mg of TB-500 (MW 889) is 11.249 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 6.511 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of TB-500 equals how many mg of Pal-GHK in moles?
2 mg of TB-500 (MW 889) is 2.25 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 1.302 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of TB-500 equals how many mg of Pal-GHK in moles?
5 mg of TB-500 (MW 889) is 5.624 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 3.255 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 15 mg vial of TB-500 equals how many mg of Pal-GHK in moles?
15 mg of TB-500 (MW 889) is 16.873 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 9.766 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of TB-500 equals how many mg of Pal-GHK in moles?
20 mg of TB-500 (MW 889) is 22.497 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 13.021 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
