What is the difference between Oxytocin and Matrixyl?
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 Matrixyl?
Oxytocin has a molecular weight of about 1007.2 g/mol and Matrixyl about 802.1 g/mol (PubChem), so Oxytocin is heavier by 205.1 g/mol, a ratio of 1.26. This means 1 mg of Oxytocin contains 992.9 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl are equimolar to 1 mg of Oxytocin?
1 mg of Oxytocin (MW 1007.2) is 992.9 nmol. The same number of moles of Matrixyl (MW 802.1) weighs 0.7964 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Oxytocin and Matrixyl
PubChem lists Oxytocin as C43H66N12O12S2 (1007.2 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). Oxytocin is a cyclic nonapeptide; Matrixyl is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Matrixyl equals how many mg of Oxytocin in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 6.279 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Matrixyl equals how many mg of Oxytocin in moles?
10 mg of Matrixyl (MW 802.1) is 12.467 µmol. The same amount of Oxytocin (MW 1007.2) would weigh 12.557 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 Matrixyl in moles?
2 mg of Oxytocin (MW 1007.2) is 1.986 µmol. The same amount of Matrixyl (MW 802.1) would weigh 1.593 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 Matrixyl in moles?
5 mg of Oxytocin (MW 1007.2) is 4.964 µmol. The same amount of Matrixyl (MW 802.1) would weigh 3.982 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
