What is the difference between Hexarelin and Semax?

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 Semax?

Hexarelin has a molecular weight of about 887 g/mol and Semax about 813.9 g/mol (PubChem), so Hexarelin is heavier by 73.1 g/mol, a ratio of 1.09. This means 1 mg of Hexarelin contains 1,127.4 nmol versus 1,228.7 nmol for Semax.

How many mg of Semax are equimolar to 1 mg of Hexarelin?

1 mg of Hexarelin (MW 887) is 1,127.4 nmol. The same number of moles of Semax (MW 813.9) weighs 0.9176 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Hexarelin and Semax

PubChem lists Hexarelin as C47H58N12O6 (887 g/mol) and Semax as C37H51N9O10S (813.9 g/mol). Hexarelin is a peptide; Semax 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 Semax in moles?

2 mg of Hexarelin (MW 887) is 2.255 µmol. The same amount of Semax (MW 813.9) would weigh 1.835 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 Semax in moles?

5 mg of Hexarelin (MW 887) is 5.637 µmol. The same amount of Semax (MW 813.9) would weigh 4.588 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 Semax in moles?

10 mg of Hexarelin (MW 887) is 11.274 µmol. The same amount of Semax (MW 813.9) would weigh 9.176 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of Semax equals how many mg of Hexarelin in moles?

5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of Hexarelin (MW 887) would weigh 5.449 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of Semax equals how many mg of Hexarelin in moles?

10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of Hexarelin (MW 887) would weigh 10.898 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 30 mg vial of Semax equals how many mg of Hexarelin in moles?

30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of Hexarelin (MW 887) would weigh 32.694 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
