What is the difference between Sermorelin and IGF-1 LR3?
Sermorelin is the 29-residue N-terminal fragment of growth hormone-releasing hormone, the shortest fully active GHRH fragment, used in GHRH receptor research (peptide, MW about 3357.9 g/mol).
Which is heavier, Sermorelin or IGF-1 LR3?
Sermorelin has a molecular weight of about 3357.9 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 5,753.1 g/mol, a ratio of 2.71. This means 1 mg of Sermorelin contains 297.8 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of Sermorelin?
1 mg of Sermorelin (MW 3357.9) is 297.8 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 2.713 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 Sermorelin in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 0.03686 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 Sermorelin in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 0.3686 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Sermorelin equals how many mg of IGF-1 LR3 in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 5.427 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Sermorelin equals how many mg of IGF-1 LR3 in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 13.567 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Sermorelin equals how many mg of IGF-1 LR3 in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 27.133 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
