What is the difference between GHRP-2 and LL-37?
GHRP-2 is a synthetic growth hormone secretagogue hexapeptide studied as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 818 g/mol).
Which is heavier, GHRP-2 or LL-37?
GHRP-2 has a molecular weight of about 818 g/mol and LL-37 about 4493 g/mol (PubChem), so LL-37 is heavier by 3,675 g/mol, a ratio of 5.49. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 222.6 nmol for LL-37.
How many mg of LL-37 are equimolar to 1 mg of GHRP-2?
1 mg of GHRP-2 (MW 818) is 1,222.5 nmol. The same number of moles of LL-37 (MW 4493) weighs 5.493 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-2 and LL-37
PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and LL-37 as C205H340N60O53 (4493 g/mol). GHRP-2 is a peptide; LL-37 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-2 equals how many mg of LL-37 in moles?
5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of LL-37 (MW 4493) would weigh 27.463 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-2 equals how many mg of LL-37 in moles?
10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of LL-37 (MW 4493) would weigh 54.927 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 GHRP-2 in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of GHRP-2 (MW 818) would weigh 1.821 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 GHRP-2 in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of GHRP-2 (MW 818) would weigh 0.9103 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
