What is the difference between Thymosin alpha-1 and IGF-1 LR3?
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 IGF-1 LR3?
Thymosin alpha-1 has a molecular weight of about 3108.3 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 6,002.7 g/mol, a ratio of 2.93. This means 1 mg of Thymosin alpha-1 contains 321.7 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 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 IGF-1 LR3 (MW 9111) weighs 2.931 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
A 0.1 mg vial of IGF-1 LR3 equals how many mg of Thymosin alpha-1 in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 0.03412 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 1 mg vial of IGF-1 LR3 equals how many mg of Thymosin alpha-1 in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of Thymosin alpha-1 (MW 3108.3) would weigh 0.3412 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 IGF-1 LR3 in moles?
5 mg of Thymosin alpha-1 (MW 3108.3) is 1.609 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 14.656 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 IGF-1 LR3 in moles?
10 mg of Thymosin alpha-1 (MW 3108.3) is 3.217 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 29.312 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
