What is the difference between Tesamorelin and Thymosin alpha-1?
Tesamorelin is a stabilised analogue of the full 44-residue GHRH with an N-terminal trans-3-hexenoyl group, used in GHRH receptor research (peptide, MW about 5136 g/mol).
Which is heavier, Tesamorelin or Thymosin alpha-1?
Tesamorelin has a molecular weight of about 5136 g/mol and Thymosin alpha-1 about 3108.3 g/mol (PubChem), so Tesamorelin is heavier by 2,027.7 g/mol, a ratio of 1.65. This means 1 mg of Tesamorelin contains 194.7 nmol versus 321.7 nmol for Thymosin alpha-1.
How many mg of Thymosin alpha-1 are equimolar to 1 mg of Tesamorelin?
1 mg of Tesamorelin (MW 5136) is 194.7 nmol. The same number of moles of Thymosin alpha-1 (MW 3108.3) weighs 0.6052 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Tesamorelin and Thymosin alpha-1
PubChem lists Tesamorelin as C221H366N72O67S (5136 g/mol) and Thymosin alpha-1 as C129H215N33O55 (3108.3 g/mol). Tesamorelin is a peptide; Thymosin alpha-1 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of Tesamorelin equals how many mg of Thymosin alpha-1 in moles?
2 mg of Tesamorelin (MW 5136) is 0.3894 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 1.21 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Tesamorelin equals how many mg of Thymosin alpha-1 in moles?
10 mg of Tesamorelin (MW 5136) is 1.947 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 6.052 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Tesamorelin equals how many mg of Thymosin alpha-1 in moles?
5 mg of Tesamorelin (MW 5136) is 0.9735 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 3.026 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Tesamorelin equals how many mg of Thymosin alpha-1 in moles?
20 mg of Tesamorelin (MW 5136) is 3.894 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 12.104 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Thymosin alpha-1 equals how many mg of Tesamorelin in moles?
