What is the difference between Sermorelin and Cartalax?
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 Cartalax?
Sermorelin has a molecular weight of about 3357.9 g/mol and Cartalax about 333.29 g/mol (PubChem), so Sermorelin is heavier by 3,024.6 g/mol, a ratio of 10.08. This means 1 mg of Sermorelin contains 297.8 nmol versus 3,000.4 nmol for Cartalax.
How many mg of Cartalax are equimolar to 1 mg of Sermorelin?
1 mg of Sermorelin (MW 3357.9) is 297.8 nmol. The same number of moles of Cartalax (MW 333.29) weighs 0.09926 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Sermorelin and Cartalax
PubChem lists Sermorelin as C149H246N44O42S (3357.9 g/mol) and Cartalax as C12H19N3O8 (333.29 g/mol). Sermorelin is a peptide; Cartalax is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Cartalax equals how many mg of Sermorelin in moles?
10 mg of Cartalax (MW 333.29) is 30.004 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 100.8 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Cartalax equals how many mg of Sermorelin in moles?
20 mg of Cartalax (MW 333.29) is 60.008 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 201.5 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 Cartalax in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of Cartalax (MW 333.29) would weigh 0.1985 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 Cartalax in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of Cartalax (MW 333.29) would weigh 0.4963 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 Cartalax in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of Cartalax (MW 333.29) would weigh 0.9926 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
