What is the difference between GHRP-2 and Selank?
GHRP-2 is a synthetic growth hormone secretagogue hexapeptide studied as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 818 g/mol).
Which is heavier, GHRP-2 or Selank?
GHRP-2 has a molecular weight of about 818 g/mol and Selank about 751.9 g/mol (PubChem), so GHRP-2 is heavier by 66.1 g/mol, a ratio of 1.09. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 1,330 nmol for Selank.
How many mg of Selank are equimolar to 1 mg of GHRP-2?
1 mg of GHRP-2 (MW 818) is 1,222.5 nmol. The same number of moles of Selank (MW 751.9) weighs 0.9192 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-2 and Selank
PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and Selank as C33H57N11O9 (751.9 g/mol). GHRP-2 is a peptide; Selank is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-2 equals how many mg of Selank in moles?
5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of Selank (MW 751.9) would weigh 4.596 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-2 equals how many mg of Selank in moles?
10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of Selank (MW 751.9) would weigh 9.192 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-2 in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of GHRP-2 (MW 818) would weigh 5.44 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-2 in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of GHRP-2 (MW 818) would weigh 10.879 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
