What is the difference between Thymosin alpha-1 and N-Acetyl Epitalon?
Thymosin alpha-1 is a 28-residue N-acetylated peptide originally isolated from thymus tissue (thymosin fraction 5), studied in immunology research (peptide, MW about 3108.3 g/mol).
Which is heavier, Thymosin alpha-1 or N-Acetyl Epitalon?
Thymosin alpha-1 has a molecular weight of about 3108.3 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so Thymosin alpha-1 is heavier by 2,675.9 g/mol, a ratio of 7.19. This means 1 mg of Thymosin alpha-1 contains 321.7 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.
How many mg of N-Acetyl Epitalon are equimolar to 1 mg of Thymosin alpha-1?
1 mg of Thymosin alpha-1 (MW 3108.3) is 321.7 nmol. The same number of moles of N-Acetyl Epitalon (MW 432.38) weighs 0.1391 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Thymosin alpha-1 and N-Acetyl Epitalon
PubChem lists Thymosin alpha-1 as C129H215N33O55 (3108.3 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). Thymosin alpha-1 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 N-Acetyl Epitalon equals how many mg of Thymosin alpha-1 in moles?
5 mg of N-Acetyl Epitalon (MW 432.38) is 11.564 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 35.944 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 N-Acetyl Epitalon in moles?
5 mg of Thymosin alpha-1 (MW 3108.3) is 1.609 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 0.6955 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Thymosin alpha-1 equals how many mg of N-Acetyl Epitalon in moles?
10 mg of Thymosin alpha-1 (MW 3108.3) is 3.217 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 1.391 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
