What is the difference between Hexarelin and SS-31?

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 SS-31?

Hexarelin has a molecular weight of about 887 g/mol and SS-31 about 639.8 g/mol (PubChem), so Hexarelin is heavier by 247.2 g/mol, a ratio of 1.39. This means 1 mg of Hexarelin contains 1,127.4 nmol versus 1,563 nmol for SS-31.

How many mg of SS-31 are equimolar to 1 mg of Hexarelin?

1 mg of Hexarelin (MW 887) is 1,127.4 nmol. The same number of moles of SS-31 (MW 639.8) weighs 0.7213 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Hexarelin and SS-31

PubChem lists Hexarelin as C47H58N12O6 (887 g/mol) and SS-31 as C32H49N9O5 (639.8 g/mol). Hexarelin is a peptide; SS-31 is a peptide. These formulas refer to the parent compounds without salt counter-ions.

A 2 mg vial of Hexarelin equals how many mg of SS-31 in moles?

2 mg of Hexarelin (MW 887) is 2.255 µmol. The same amount of SS-31 (MW 639.8) would weigh 1.443 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 SS-31 in moles?

5 mg of Hexarelin (MW 887) is 5.637 µmol. The same amount of SS-31 (MW 639.8) would weigh 3.607 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 SS-31 in moles?

10 mg of Hexarelin (MW 887) is 11.274 µmol. The same amount of SS-31 (MW 639.8) would weigh 7.213 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of SS-31 equals how many mg of Hexarelin in moles?

5 mg of SS-31 (MW 639.8) is 7.815 µmol. The same amount of Hexarelin (MW 887) would weigh 6.932 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of SS-31 equals how many mg of Hexarelin in moles?

10 mg of SS-31 (MW 639.8) is 15.63 µmol. The same amount of Hexarelin (MW 887) would weigh 13.864 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
