What is the difference between Gonadorelin and Melanotan II?
Gonadorelin is the synthetic form of native gonadotropin-releasing hormone, a decapeptide used as a reference agonist in GnRH receptor research (peptide, MW about 1182.3 g/mol).
Which is heavier, Gonadorelin or Melanotan II?
Gonadorelin has a molecular weight of about 1182.3 g/mol and Melanotan II about 1024.2 g/mol (PubChem), so Gonadorelin is heavier by 158.1 g/mol, a ratio of 1.15. This means 1 mg of Gonadorelin contains 845.8 nmol versus 976.4 nmol for Melanotan II.
How many mg of Melanotan II are equimolar to 1 mg of Gonadorelin?
1 mg of Gonadorelin (MW 1182.3) is 845.8 nmol. The same number of moles of Melanotan II (MW 1024.2) weighs 0.8663 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Gonadorelin and Melanotan II
PubChem lists Gonadorelin as C55H75N17O13 (1182.3 g/mol) and Melanotan II as C50H69N15O9 (1024.2 g/mol). Gonadorelin is a peptide; Melanotan II is a cyclic peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Gonadorelin equals how many mg of Melanotan II in moles?
5 mg of Gonadorelin (MW 1182.3) is 4.229 µmol. The same amount of Melanotan II (MW 1024.2) would weigh 4.331 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Gonadorelin equals how many mg of Melanotan II in moles?
10 mg of Gonadorelin (MW 1182.3) is 8.458 µmol. The same amount of Melanotan II (MW 1024.2) would weigh 8.663 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Melanotan II equals how many mg of Gonadorelin in moles?
10 mg of Melanotan II (MW 1024.2) is 9.764 µmol. The same amount of Gonadorelin (MW 1182.3) would weigh 11.544 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Melanotan II equals how many mg of Gonadorelin in moles?
5 mg of Melanotan II (MW 1024.2) is 4.882 µmol. The same amount of Gonadorelin (MW 1182.3) would weigh 5.772 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
