What is the difference between Oxytocin and SNAP-8?
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 SNAP-8?
Oxytocin has a molecular weight of about 1007.2 g/mol and SNAP-8 about 1075.2 g/mol (PubChem), so SNAP-8 is heavier by 68 g/mol, a ratio of 1.07. This means 1 mg of Oxytocin contains 992.9 nmol versus 930.1 nmol for SNAP-8.
How many mg of SNAP-8 are equimolar to 1 mg of Oxytocin?
1 mg of Oxytocin (MW 1007.2) is 992.9 nmol. The same number of moles of SNAP-8 (MW 1075.2) weighs 1.068 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Oxytocin and SNAP-8
PubChem lists Oxytocin as C43H66N12O12S2 (1007.2 g/mol) and SNAP-8 as C41H70N16O16S (1075.2 g/mol). Oxytocin is a cyclic nonapeptide; SNAP-8 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 SNAP-8 in moles?
2 mg of Oxytocin (MW 1007.2) is 1.986 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 2.135 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 SNAP-8 in moles?
5 mg of Oxytocin (MW 1007.2) is 4.964 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 5.338 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of SNAP-8 equals how many mg of Oxytocin in moles?
5 mg of SNAP-8 (MW 1075.2) is 4.65 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 4.684 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of SNAP-8 equals how many mg of Oxytocin in moles?
10 mg of SNAP-8 (MW 1075.2) is 9.301 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 9.368 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
