What is the difference between GHRP-6 and Oxytocin?
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 Oxytocin?
GHRP-6 has a molecular weight of about 873 g/mol and Oxytocin about 1007.2 g/mol (PubChem), so Oxytocin is heavier by 134.2 g/mol, a ratio of 1.15. This means 1 mg of GHRP-6 contains 1,145.5 nmol versus 992.9 nmol for Oxytocin.
How many mg of Oxytocin 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 Oxytocin (MW 1007.2) weighs 1.154 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-6 and Oxytocin
PubChem lists GHRP-6 as C46H56N12O6 (873 g/mol) and Oxytocin as C43H66N12O12S2 (1007.2 g/mol). GHRP-6 is a peptide; Oxytocin is a cyclic nonapeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-6 equals how many mg of Oxytocin in moles?
5 mg of GHRP-6 (MW 873) is 5.727 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 5.769 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 Oxytocin in moles?
10 mg of GHRP-6 (MW 873) is 11.455 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 11.537 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Oxytocin equals how many mg of GHRP-6 in moles?
2 mg of Oxytocin (MW 1007.2) is 1.986 µmol. The same amount of GHRP-6 (MW 873) would weigh 1.734 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Oxytocin equals how many mg of GHRP-6 in moles?
5 mg of Oxytocin (MW 1007.2) is 4.964 µmol. The same amount of GHRP-6 (MW 873) would weigh 4.334 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
