What is the difference between Ipamorelin and Matrixyl?
Ipamorelin is a pentapeptide ghrelin receptor agonist reported in 1998 as a selective growth hormone secretagogue in endocrine research (peptide, MW about 711.9 g/mol).
Which is heavier, Ipamorelin or Matrixyl?
Ipamorelin has a molecular weight of about 711.9 g/mol and Matrixyl about 802.1 g/mol (PubChem), so Matrixyl is heavier by 90.2 g/mol, a ratio of 1.13. This means 1 mg of Ipamorelin contains 1,404.7 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl are equimolar to 1 mg of Ipamorelin?
1 mg of Ipamorelin (MW 711.9) is 1,404.7 nmol. The same number of moles of Matrixyl (MW 802.1) weighs 1.127 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Ipamorelin and Matrixyl
PubChem lists Ipamorelin as C38H49N9O5 (711.9 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). Ipamorelin is a peptide; Matrixyl is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of Ipamorelin equals how many mg of Matrixyl in moles?
2 mg of Ipamorelin (MW 711.9) is 2.809 µmol. The same amount of Matrixyl (MW 802.1) would weigh 2.253 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Ipamorelin equals how many mg of Matrixyl in moles?
10 mg of Ipamorelin (MW 711.9) is 14.047 µmol. The same amount of Matrixyl (MW 802.1) would weigh 11.267 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Ipamorelin equals how many mg of Matrixyl in moles?
5 mg of Ipamorelin (MW 711.9) is 7.023 µmol. The same amount of Matrixyl (MW 802.1) would weigh 5.634 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Matrixyl equals how many mg of Ipamorelin in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 4.438 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 Ipamorelin in moles?
10 mg of Matrixyl (MW 802.1) is 12.467 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 8.875 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
