What is the difference between Hexarelin and PT-141?
Hexarelin is a synthetic hexapeptide growth hormone secretagogue, also studied for binding to the CD36 receptor in cardiovascular research models (peptide, MW about 887 g/mol).
Which is heavier, Hexarelin or PT-141?
Hexarelin has a molecular weight of about 887 g/mol and PT-141 about 1025.2 g/mol (PubChem), so PT-141 is heavier by 138.2 g/mol, a ratio of 1.16. This means 1 mg of Hexarelin contains 1,127.4 nmol versus 975.4 nmol for PT-141.
How many mg of PT-141 are equimolar to 1 mg of Hexarelin?
1 mg of Hexarelin (MW 887) is 1,127.4 nmol. The same number of moles of PT-141 (MW 1025.2) weighs 1.156 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Hexarelin and PT-141
PubChem lists Hexarelin as C47H58N12O6 (887 g/mol) and PT-141 as C50H68N14O10 (1025.2 g/mol). Hexarelin is a peptide; PT-141 is a cyclic peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of Hexarelin equals how many mg of PT-141 in moles?
2 mg of Hexarelin (MW 887) is 2.255 µmol. The same amount of PT-141 (MW 1025.2) would weigh 2.312 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Hexarelin equals how many mg of PT-141 in moles?
5 mg of Hexarelin (MW 887) is 5.637 µmol. The same amount of PT-141 (MW 1025.2) would weigh 5.779 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Hexarelin equals how many mg of PT-141 in moles?
10 mg of Hexarelin (MW 887) is 11.274 µmol. The same amount of PT-141 (MW 1025.2) would weigh 11.558 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of PT-141 equals how many mg of Hexarelin in moles?
10 mg of PT-141 (MW 1025.2) is 9.754 µmol. The same amount of Hexarelin (MW 887) would weigh 8.652 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of PT-141 equals how many mg of Hexarelin in moles?
5 mg of PT-141 (MW 1025.2) is 4.877 µmol. The same amount of Hexarelin (MW 887) would weigh 4.326 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
