What is the difference between Ipamorelin and IGF-1 LR3?
Ipamorelin is a pentapeptide ghrelin receptor agonist reported in 1998 as a selective growth hormone secretagogue in endocrine research (peptide, MW about 711.9 g/mol).
Which is heavier, Ipamorelin or IGF-1 LR3?
Ipamorelin has a molecular weight of about 711.9 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,399.1 g/mol, a ratio of 12.8. This means 1 mg of Ipamorelin contains 1,404.7 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of Ipamorelin?
1 mg of Ipamorelin (MW 711.9) is 1,404.7 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 12.798 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 Ipamorelin in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 0.007814 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 Ipamorelin in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 0.07814 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Ipamorelin equals how many mg of IGF-1 LR3 in moles?
2 mg of Ipamorelin (MW 711.9) is 2.809 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 25.596 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Ipamorelin equals how many mg of IGF-1 LR3 in moles?
10 mg of Ipamorelin (MW 711.9) is 14.047 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 128 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Ipamorelin equals how many mg of IGF-1 LR3 in moles?
5 mg of Ipamorelin (MW 711.9) is 7.023 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 63.991 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
