What is the difference between GHRP-6 and Selank?
GHRP-6 is one of the earliest synthetic growth hormone secretagogue hexapeptides, used as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 873 g/mol).
Which is heavier, GHRP-6 or Selank?
GHRP-6 has a molecular weight of about 873 g/mol and Selank about 751.9 g/mol (PubChem), so GHRP-6 is heavier by 121.1 g/mol, a ratio of 1.16. This means 1 mg of GHRP-6 contains 1,145.5 nmol versus 1,330 nmol for Selank.
How many mg of Selank are equimolar to 1 mg of GHRP-6?
1 mg of GHRP-6 (MW 873) is 1,145.5 nmol. The same number of moles of Selank (MW 751.9) weighs 0.8613 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-6 and Selank
PubChem lists GHRP-6 as C46H56N12O6 (873 g/mol) and Selank as C33H57N11O9 (751.9 g/mol). GHRP-6 is a peptide; Selank is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-6 equals how many mg of Selank in moles?
5 mg of GHRP-6 (MW 873) is 5.727 µmol. The same amount of Selank (MW 751.9) would weigh 4.306 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-6 equals how many mg of Selank in moles?
10 mg of GHRP-6 (MW 873) is 11.455 µmol. The same amount of Selank (MW 751.9) would weigh 8.613 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 GHRP-6 in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of GHRP-6 (MW 873) would weigh 5.805 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 GHRP-6 in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of GHRP-6 (MW 873) would weigh 11.611 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
