What is the difference between Ipamorelin and Selank?
Ipamorelin is a pentapeptide ghrelin receptor agonist reported in 1998 as a selective growth hormone secretagogue in endocrine research (peptide, MW about 711.9 g/mol).
Which is heavier, Ipamorelin or Selank?
Ipamorelin has a molecular weight of about 711.9 g/mol and Selank about 751.9 g/mol (PubChem), so Selank is heavier by 40 g/mol, a ratio of 1.06. This means 1 mg of Ipamorelin contains 1,404.7 nmol versus 1,330 nmol for Selank.
How many mg of Selank are equimolar to 1 mg of Ipamorelin?
1 mg of Ipamorelin (MW 711.9) is 1,404.7 nmol. The same number of moles of Selank (MW 751.9) weighs 1.056 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Ipamorelin and Selank
PubChem lists Ipamorelin as C38H49N9O5 (711.9 g/mol) and Selank as C33H57N11O9 (751.9 g/mol). Ipamorelin is a peptide; Selank is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of Ipamorelin equals how many mg of Selank in moles?
2 mg of Ipamorelin (MW 711.9) is 2.809 µmol. The same amount of Selank (MW 751.9) would weigh 2.112 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Ipamorelin equals how many mg of Selank in moles?
10 mg of Ipamorelin (MW 711.9) is 14.047 µmol. The same amount of Selank (MW 751.9) would weigh 10.562 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Ipamorelin equals how many mg of Selank in moles?
5 mg of Ipamorelin (MW 711.9) is 7.023 µmol. The same amount of Selank (MW 751.9) would weigh 5.281 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 Ipamorelin in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 4.734 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 Ipamorelin in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 9.468 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
