What is the difference between KPV and Melanotan II?
KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone, studied in inflammation-signalling research in cell and rodent models (peptide, MW about 342.43 g/mol).
Which is heavier, KPV or Melanotan II?
KPV has a molecular weight of about 342.43 g/mol and Melanotan II about 1024.2 g/mol (PubChem), so Melanotan II is heavier by 681.8 g/mol, a ratio of 2.99. This means 1 mg of KPV contains 2,920.3 nmol versus 976.4 nmol for Melanotan II.
How many mg of Melanotan II are equimolar to 1 mg of KPV?
1 mg of KPV (MW 342.43) is 2,920.3 nmol. The same number of moles of Melanotan II (MW 1024.2) weighs 2.991 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of KPV and Melanotan II
PubChem lists KPV as C16H30N4O4 (342.43 g/mol) and Melanotan II as C50H69N15O9 (1024.2 g/mol). KPV is a peptide; Melanotan II is a cyclic peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of KPV equals how many mg of Melanotan II in moles?
2 mg of KPV (MW 342.43) is 5.841 µmol. The same amount of Melanotan II (MW 1024.2) would weigh 5.982 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of KPV equals how many mg of Melanotan II in moles?
5 mg of KPV (MW 342.43) is 14.602 µmol. The same amount of Melanotan II (MW 1024.2) would weigh 14.955 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of KPV equals how many mg of Melanotan II in moles?
10 mg of KPV (MW 342.43) is 29.203 µmol. The same amount of Melanotan II (MW 1024.2) would weigh 29.91 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of KPV equals how many mg of Melanotan II in moles?
20 mg of KPV (MW 342.43) is 58.406 µmol. The same amount of Melanotan II (MW 1024.2) would weigh 59.82 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
