What is the difference between Ipamorelin and LL-37?
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 LL-37?
Ipamorelin has a molecular weight of about 711.9 g/mol and LL-37 about 4493 g/mol (PubChem), so LL-37 is heavier by 3,781.1 g/mol, a ratio of 6.31. This means 1 mg of Ipamorelin contains 1,404.7 nmol versus 222.6 nmol for LL-37.
How many mg of LL-37 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 LL-37 (MW 4493) weighs 6.311 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Ipamorelin and LL-37
PubChem lists Ipamorelin as C38H49N9O5 (711.9 g/mol) and LL-37 as C205H340N60O53 (4493 g/mol). Ipamorelin is a peptide; LL-37 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of Ipamorelin equals how many mg of LL-37 in moles?
2 mg of Ipamorelin (MW 711.9) is 2.809 µmol. The same amount of LL-37 (MW 4493) would weigh 12.623 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 LL-37 in moles?
10 mg of Ipamorelin (MW 711.9) is 14.047 µmol. The same amount of LL-37 (MW 4493) would weigh 63.113 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 LL-37 in moles?
5 mg of Ipamorelin (MW 711.9) is 7.023 µmol. The same amount of LL-37 (MW 4493) would weigh 31.556 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of LL-37 equals how many mg of Ipamorelin in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 1.584 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of LL-37 equals how many mg of Ipamorelin in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 0.7922 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
