What is the difference between GHRP-2 and Oxytocin?
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 Oxytocin?
GHRP-2 has a molecular weight of about 818 g/mol and Oxytocin about 1007.2 g/mol (PubChem), so Oxytocin is heavier by 189.2 g/mol, a ratio of 1.23. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 992.9 nmol for Oxytocin.
How many mg of Oxytocin 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 Oxytocin (MW 1007.2) weighs 1.231 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-2 and Oxytocin
PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and Oxytocin as C43H66N12O12S2 (1007.2 g/mol). GHRP-2 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-2 equals how many mg of Oxytocin in moles?
5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 6.156 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 Oxytocin in moles?
10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 12.313 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-2 in moles?
2 mg of Oxytocin (MW 1007.2) is 1.986 µmol. The same amount of GHRP-2 (MW 818) would weigh 1.624 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-2 in moles?
5 mg of Oxytocin (MW 1007.2) is 4.964 µmol. The same amount of GHRP-2 (MW 818) would weigh 4.061 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
