What is the difference between N-Acetyl Epitalon and IGF-1 LR3?
N-Acetyl Epitalon is the N-terminally acetylated form of the Epitalon tetrapeptide; acetylation removes the free N-terminal amine and is used in research to compare stability against the parent peptide (peptide, MW about 432.38 g/mol).

What is the difference between N-Acetyl Epitalon and IGF-1 LR3?
N-Acetyl Epitalon is the N-terminally acetylated form of the Epitalon tetrapeptide; acetylation removes the free N-terminal amine and is used in research to compare stability against the parent peptide (peptide, MW about 432.38 g/mol).
Which is heavier, N-Acetyl Epitalon or IGF-1 LR3?
N-Acetyl Epitalon has a molecular weight of about 432.38 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,678.6 g/mol, a ratio of 21.07. This means 1 mg of N-Acetyl Epitalon contains 2,312.8 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of N-Acetyl Epitalon?
1 mg of N-Acetyl Epitalon (MW 432.38) is 2,312.8 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 21.072 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 N-Acetyl Epitalon in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 0.004746 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 N-Acetyl Epitalon in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 0.04746 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of N-Acetyl Epitalon equals how many mg of IGF-1 LR3 in moles?
5 mg of N-Acetyl Epitalon (MW 432.38) is 11.564 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 105.4 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
