What is the difference between Thymosin alpha-1 and Pal-GHK?
Thymosin alpha-1 is a 28-residue N-acetylated peptide originally isolated from thymus tissue (thymosin fraction 5), studied in immunology research (peptide, MW about 3108.3 g/mol).
Which is heavier, Thymosin alpha-1 or Pal-GHK?
Thymosin alpha-1 has a molecular weight of about 3108.3 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so Thymosin alpha-1 is heavier by 2,529.5 g/mol, a ratio of 5.37. This means 1 mg of Thymosin alpha-1 contains 321.7 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK are equimolar to 1 mg of Thymosin alpha-1?
1 mg of Thymosin alpha-1 (MW 3108.3) is 321.7 nmol. The same number of moles of Pal-GHK (MW 578.8) weighs 0.1862 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Thymosin alpha-1 and Pal-GHK
PubChem lists Thymosin alpha-1 as C129H215N33O55 (3108.3 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). Thymosin alpha-1 is a peptide; Pal-GHK is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Pal-GHK equals how many mg of Thymosin alpha-1 in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 53.702 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Thymosin alpha-1 equals how many mg of Pal-GHK in moles?
5 mg of Thymosin alpha-1 (MW 3108.3) is 1.609 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 0.9311 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Thymosin alpha-1 equals how many mg of Pal-GHK in moles?
10 mg of Thymosin alpha-1 (MW 3108.3) is 3.217 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 1.862 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
