What is the difference between LL-37 and SLU-PP-332?
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 SLU-PP-332?
LL-37 has a molecular weight of about 4493 g/mol and SLU-PP-332 about 290.3 g/mol (PubChem), so LL-37 is heavier by 4,202.7 g/mol, a ratio of 15.48. This means 1 mg of LL-37 contains 222.6 nmol versus 3,444.7 nmol for SLU-PP-332.
How many mg of SLU-PP-332 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 SLU-PP-332 (MW 290.3) weighs 0.06461 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of LL-37 and SLU-PP-332
PubChem lists LL-37 as C205H340N60O53 (4493 g/mol) and SLU-PP-332 as C18H14N2O2 (290.3 g/mol). LL-37 is a peptide; SLU-PP-332 is a small molecule (not 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 SLU-PP-332 in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of SLU-PP-332 (MW 290.3) would weigh 0.6461 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 SLU-PP-332 in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of SLU-PP-332 (MW 290.3) would weigh 0.3231 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of SLU-PP-332 equals how many mg of LL-37 in moles?
10 mg of SLU-PP-332 (MW 290.3) is 34.447 µmol. The same amount of LL-37 (MW 4493) would weigh 154.8 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of SLU-PP-332 equals how many mg of LL-37 in moles?
5 mg of SLU-PP-332 (MW 290.3) is 17.224 µmol. The same amount of LL-37 (MW 4493) would weigh 77.385 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
