What is the difference between Oxytocin and Sermorelin?
Oxytocin is a nonapeptide neurohypophysial hormone with a disulfide bridge, used as a reference agonist in oxytocin receptor and social-neuroscience research (cyclic nonapeptide, MW about 1007.2 g/mol).
Which is heavier, Oxytocin or Sermorelin?
Oxytocin has a molecular weight of about 1007.2 g/mol and Sermorelin about 3357.9 g/mol (PubChem), so Sermorelin is heavier by 2,350.7 g/mol, a ratio of 3.33. This means 1 mg of Oxytocin contains 992.9 nmol versus 297.8 nmol for Sermorelin.
How many mg of Sermorelin are equimolar to 1 mg of Oxytocin?
1 mg of Oxytocin (MW 1007.2) is 992.9 nmol. The same number of moles of Sermorelin (MW 3357.9) weighs 3.334 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Oxytocin and Sermorelin
PubChem lists Oxytocin as C43H66N12O12S2 (1007.2 g/mol) and Sermorelin as C149H246N44O42S (3357.9 g/mol). Oxytocin is a cyclic nonapeptide; Sermorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of Oxytocin equals how many mg of Sermorelin in moles?
2 mg of Oxytocin (MW 1007.2) is 1.986 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 6.668 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 Sermorelin in moles?
5 mg of Oxytocin (MW 1007.2) is 4.964 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 16.669 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Sermorelin equals how many mg of Oxytocin in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 0.5999 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Sermorelin equals how many mg of Oxytocin in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 1.5 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Sermorelin equals how many mg of Oxytocin in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 2.999 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
