What is the difference between Sermorelin and Matrixyl?
Sermorelin is the 29-residue N-terminal fragment of growth hormone-releasing hormone, the shortest fully active GHRH fragment, used in GHRH receptor research (peptide, MW about 3357.9 g/mol).
Which is heavier, Sermorelin or Matrixyl?
Sermorelin has a molecular weight of about 3357.9 g/mol and Matrixyl about 802.1 g/mol (PubChem), so Sermorelin is heavier by 2,555.8 g/mol, a ratio of 4.19. This means 1 mg of Sermorelin contains 297.8 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl are equimolar to 1 mg of Sermorelin?
1 mg of Sermorelin (MW 3357.9) is 297.8 nmol. The same number of moles of Matrixyl (MW 802.1) weighs 0.2389 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Sermorelin and Matrixyl
PubChem lists Sermorelin as C149H246N44O42S (3357.9 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). Sermorelin is a peptide; 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 Sermorelin in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 20.932 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 Sermorelin in moles?
10 mg of Matrixyl (MW 802.1) is 12.467 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 41.864 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 Matrixyl in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of Matrixyl (MW 802.1) would weigh 0.4777 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 Matrixyl in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of Matrixyl (MW 802.1) would weigh 1.194 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 Matrixyl in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of Matrixyl (MW 802.1) would weigh 2.389 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
