What is the difference between Oxytocin and Selank?
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 Selank?
Oxytocin has a molecular weight of about 1007.2 g/mol and Selank about 751.9 g/mol (PubChem), so Oxytocin is heavier by 255.3 g/mol, a ratio of 1.34. This means 1 mg of Oxytocin contains 992.9 nmol versus 1,330 nmol for Selank.
How many mg of Selank are equimolar to 1 mg of Oxytocin?
1 mg of Oxytocin (MW 1007.2) is 992.9 nmol. The same number of moles of Selank (MW 751.9) weighs 0.7465 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Oxytocin and Selank
PubChem lists Oxytocin as C43H66N12O12S2 (1007.2 g/mol) and Selank as C33H57N11O9 (751.9 g/mol). Oxytocin is a cyclic nonapeptide; Selank 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 Selank in moles?
2 mg of Oxytocin (MW 1007.2) is 1.986 µmol. The same amount of Selank (MW 751.9) would weigh 1.493 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 Selank in moles?
5 mg of Oxytocin (MW 1007.2) is 4.964 µmol. The same amount of Selank (MW 751.9) would weigh 3.733 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 Oxytocin in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 6.698 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 Oxytocin in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 13.395 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
