What is the difference between Selank and Matrixyl?
Selank is a synthetic heptapeptide analogue of tuftsin extended with Pro-Gly-Pro, developed at the Institute of Molecular Genetics in Russia and studied in neuropeptide research (peptide, MW about 751.9 g/mol).
Which is heavier, Selank or Matrixyl?
Selank has a molecular weight of about 751.9 g/mol and Matrixyl about 802.1 g/mol (PubChem), so Matrixyl is heavier by 50.2 g/mol, a ratio of 1.07. This means 1 mg of Selank contains 1,330 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl are equimolar to 1 mg of Selank?
1 mg of Selank (MW 751.9) is 1,330 nmol. The same number of moles of Matrixyl (MW 802.1) weighs 1.067 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Selank and Matrixyl
PubChem lists Selank as C33H57N11O9 (751.9 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). Selank 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 Selank in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of Selank (MW 751.9) would weigh 4.687 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 Selank in moles?
10 mg of Matrixyl (MW 802.1) is 12.467 µmol. The same amount of Selank (MW 751.9) would weigh 9.374 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Selank equals how many mg of Matrixyl in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Matrixyl (MW 802.1) would weigh 5.334 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Selank equals how many mg of Matrixyl in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Matrixyl (MW 802.1) would weigh 10.668 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
