What is the difference between LL-37 and Pal-GHK?
LL-37 is the 37-residue active fragment of the human cathelicidin hCAP18, studied in antimicrobial-peptide and innate-immunity research (peptide, MW about 4493 g/mol).
Which is heavier, LL-37 or Pal-GHK?
LL-37 has a molecular weight of about 4493 g/mol and Pal-GHK about 578.8 g/mol (PubChem), so LL-37 is heavier by 3,914.2 g/mol, a ratio of 7.76. This means 1 mg of LL-37 contains 222.6 nmol versus 1,727.7 nmol for Pal-GHK.
How many mg of Pal-GHK are equimolar to 1 mg of LL-37?
1 mg of LL-37 (MW 4493) is 222.6 nmol. The same number of moles of Pal-GHK (MW 578.8) weighs 0.1288 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of LL-37 and Pal-GHK
PubChem lists LL-37 as C205H340N60O53 (4493 g/mol) and Pal-GHK as C30H54N6O5 (578.8 g/mol). LL-37 is a peptide; Pal-GHK is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of LL-37 equals how many mg of Pal-GHK in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 1.288 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 Pal-GHK in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 0.6441 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Pal-GHK equals how many mg of LL-37 in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of LL-37 (MW 4493) would weigh 77.626 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
