What is the difference between Hexarelin and Selank?
Hexarelin is a synthetic hexapeptide growth hormone secretagogue, also studied for binding to the CD36 receptor in cardiovascular research models (peptide, MW about 887 g/mol).
Which is heavier, Hexarelin or Selank?
Hexarelin has a molecular weight of about 887 g/mol and Selank about 751.9 g/mol (PubChem), so Hexarelin is heavier by 135.1 g/mol, a ratio of 1.18. This means 1 mg of Hexarelin contains 1,127.4 nmol versus 1,330 nmol for Selank.
How many mg of Selank are equimolar to 1 mg of Hexarelin?
1 mg of Hexarelin (MW 887) is 1,127.4 nmol. The same number of moles of Selank (MW 751.9) weighs 0.8477 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Hexarelin and Selank
PubChem lists Hexarelin as C47H58N12O6 (887 g/mol) and Selank as C33H57N11O9 (751.9 g/mol). Hexarelin is a peptide; Selank is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of Hexarelin equals how many mg of Selank in moles?
2 mg of Hexarelin (MW 887) is 2.255 µmol. The same amount of Selank (MW 751.9) would weigh 1.695 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Hexarelin equals how many mg of Selank in moles?
5 mg of Hexarelin (MW 887) is 5.637 µmol. The same amount of Selank (MW 751.9) would weigh 4.238 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Hexarelin equals how many mg of Selank in moles?
10 mg of Hexarelin (MW 887) is 11.274 µmol. The same amount of Selank (MW 751.9) would weigh 8.477 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Selank equals how many mg of Hexarelin in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Hexarelin (MW 887) would weigh 5.898 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Selank equals how many mg of Hexarelin in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Hexarelin (MW 887) would weigh 11.797 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
