What is the difference between LL-37 and N-Acetyl Epitalon?
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 N-Acetyl Epitalon?
LL-37 has a molecular weight of about 4493 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so LL-37 is heavier by 4,060.6 g/mol, a ratio of 10.39. This means 1 mg of LL-37 contains 222.6 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.
How many mg of N-Acetyl Epitalon 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 N-Acetyl Epitalon (MW 432.38) weighs 0.09623 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of LL-37 and N-Acetyl Epitalon
PubChem lists LL-37 as C205H340N60O53 (4493 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). LL-37 is a peptide; N-Acetyl Epitalon is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of LL-37 equals how many mg of N-Acetyl Epitalon in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 0.9623 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 N-Acetyl Epitalon in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 0.4812 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
