What is the difference between Hexarelin and Sermorelin?
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 Sermorelin?
Hexarelin has a molecular weight of about 887 g/mol and Sermorelin about 3357.9 g/mol (PubChem), so Sermorelin is heavier by 2,470.9 g/mol, a ratio of 3.79. This means 1 mg of Hexarelin contains 1,127.4 nmol versus 297.8 nmol for Sermorelin.
How many mg of Sermorelin are equimolar to 1 mg of Hexarelin?
1 mg of Hexarelin (MW 887) is 1,127.4 nmol. The same number of moles of Sermorelin (MW 3357.9) weighs 3.786 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Hexarelin and Sermorelin
PubChem lists Hexarelin as C47H58N12O6 (887 g/mol) and Sermorelin as C149H246N44O42S (3357.9 g/mol). Hexarelin is a peptide; Sermorelin 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 Sermorelin in moles?
2 mg of Hexarelin (MW 887) is 2.255 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 7.571 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 Sermorelin in moles?
5 mg of Hexarelin (MW 887) is 5.637 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 18.928 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 Sermorelin in moles?
10 mg of Hexarelin (MW 887) is 11.274 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 37.857 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Sermorelin equals how many mg of Hexarelin in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of Hexarelin (MW 887) would weigh 0.5283 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Sermorelin equals how many mg of Hexarelin in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of Hexarelin (MW 887) would weigh 1.321 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Sermorelin equals how many mg of Hexarelin in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of Hexarelin (MW 887) would weigh 2.642 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
