What is the difference between Thymosin alpha-1 and Matrixyl?
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 Matrixyl?
Thymosin alpha-1 has a molecular weight of about 3108.3 g/mol and Matrixyl about 802.1 g/mol (PubChem), so Thymosin alpha-1 is heavier by 2,306.2 g/mol, a ratio of 3.88. This means 1 mg of Thymosin alpha-1 contains 321.7 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl 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 Matrixyl (MW 802.1) weighs 0.2581 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Thymosin alpha-1 and Matrixyl
PubChem lists Thymosin alpha-1 as C129H215N33O55 (3108.3 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). Thymosin alpha-1 is a peptide; Matrixyl is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Matrixyl equals how many mg of Thymosin alpha-1 in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 19.376 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Matrixyl equals how many mg of Thymosin alpha-1 in moles?
10 mg of Matrixyl (MW 802.1) is 12.467 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 38.752 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 Matrixyl in moles?
5 mg of Thymosin alpha-1 (MW 3108.3) is 1.609 µmol. The same amount of Matrixyl (MW 802.1) would weigh 1.29 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 Matrixyl in moles?
10 mg of Thymosin alpha-1 (MW 3108.3) is 3.217 µmol. The same amount of Matrixyl (MW 802.1) would weigh 2.581 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
