What is the difference between Tesamorelin and Matrixyl?
Tesamorelin is a stabilised analogue of the full 44-residue GHRH with an N-terminal trans-3-hexenoyl group, used in GHRH receptor research (peptide, MW about 5136 g/mol).
Which is heavier, Tesamorelin or Matrixyl?
Tesamorelin has a molecular weight of about 5136 g/mol and Matrixyl about 802.1 g/mol (PubChem), so Tesamorelin is heavier by 4,333.9 g/mol, a ratio of 6.4. This means 1 mg of Tesamorelin contains 194.7 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl are equimolar to 1 mg of Tesamorelin?
1 mg of Tesamorelin (MW 5136) is 194.7 nmol. The same number of moles of Matrixyl (MW 802.1) weighs 0.1562 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Tesamorelin and Matrixyl
PubChem lists Tesamorelin as C221H366N72O67S (5136 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). Tesamorelin 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 Tesamorelin in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of Tesamorelin (MW 5136) would weigh 32.016 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 Tesamorelin in moles?
10 mg of Matrixyl (MW 802.1) is 12.467 µmol. The same amount of Tesamorelin (MW 5136) would weigh 64.032 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Tesamorelin equals how many mg of Matrixyl in moles?
2 mg of Tesamorelin (MW 5136) is 0.3894 µmol. The same amount of Matrixyl (MW 802.1) would weigh 0.3123 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Tesamorelin equals how many mg of Matrixyl in moles?
10 mg of Tesamorelin (MW 5136) is 1.947 µmol. The same amount of Matrixyl (MW 802.1) would weigh 1.562 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Tesamorelin equals how many mg of Matrixyl in moles?
5 mg of Tesamorelin (MW 5136) is 0.9735 µmol. The same amount of Matrixyl (MW 802.1) would weigh 0.7809 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Tesamorelin equals how many mg of Matrixyl in moles?
20 mg of Tesamorelin (MW 5136) is 3.894 µmol. The same amount of Matrixyl (MW 802.1) would weigh 3.123 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
