What is the difference between Melanotan I and N-Acetyl Epitalon?
Melanotan I is a linear 13-residue alpha-MSH analogue used in melanocortin-1 receptor research (peptide, MW about 1646.8 g/mol).
Which is heavier, Melanotan I or N-Acetyl Epitalon?
Melanotan I has a molecular weight of about 1646.8 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so Melanotan I is heavier by 1,214.4 g/mol, a ratio of 3.81. This means 1 mg of Melanotan I contains 607.2 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.
How many mg of N-Acetyl Epitalon are equimolar to 1 mg of Melanotan I?
1 mg of Melanotan I (MW 1646.8) is 607.2 nmol. The same number of moles of N-Acetyl Epitalon (MW 432.38) weighs 0.2626 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Melanotan I and N-Acetyl Epitalon
PubChem lists Melanotan I as C78H111N21O19 (1646.8 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). Melanotan I is a peptide; N-Acetyl Epitalon is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Melanotan I equals how many mg of N-Acetyl Epitalon in moles?
5 mg of Melanotan I (MW 1646.8) is 3.036 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 1.313 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Melanotan I equals how many mg of N-Acetyl Epitalon in moles?
10 mg of Melanotan I (MW 1646.8) is 6.072 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 2.626 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 I in moles?
5 mg of N-Acetyl Epitalon (MW 432.38) is 11.564 µmol. The same amount of Melanotan I (MW 1646.8) would weigh 19.043 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
