What is the difference between Melanotan II and N-Acetyl Epitalon?

Melanotan II is a cyclic heptapeptide alpha-MSH analogue used as a non-selective melanocortin receptor agonist in receptor-pharmacology research (cyclic peptide, MW about 1024.2 g/mol).

Which is heavier, Melanotan II or N-Acetyl Epitalon?

Melanotan II has a molecular weight of about 1024.2 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so Melanotan II is heavier by 591.8 g/mol, a ratio of 2.37. This means 1 mg of Melanotan II contains 976.4 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.

How many mg of N-Acetyl Epitalon are equimolar to 1 mg of Melanotan II?

1 mg of Melanotan II (MW 1024.2) is 976.4 nmol. The same number of moles of N-Acetyl Epitalon (MW 432.38) weighs 0.4222 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Melanotan II and N-Acetyl Epitalon

PubChem lists Melanotan II as C50H69N15O9 (1024.2 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). Melanotan II is a cyclic peptide; N-Acetyl Epitalon is a peptide. These formulas refer to the parent compounds without salt counter-ions.

A 10 mg vial of Melanotan II equals how many mg of N-Acetyl Epitalon in moles?

10 mg of Melanotan II (MW 1024.2) is 9.764 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 4.222 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 N-Acetyl Epitalon in moles?

5 mg of Melanotan II (MW 1024.2) is 4.882 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 2.111 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of N-Acetyl Epitalon equals how many mg of Melanotan II in moles?

5 mg of N-Acetyl Epitalon (MW 432.38) is 11.564 µmol. The same amount of Melanotan II (MW 1024.2) would weigh 11.844 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
