What is the difference between LL-37 and SNAP-8?
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 SNAP-8?
LL-37 has a molecular weight of about 4493 g/mol and SNAP-8 about 1075.2 g/mol (PubChem), so LL-37 is heavier by 3,417.8 g/mol, a ratio of 4.18. This means 1 mg of LL-37 contains 222.6 nmol versus 930.1 nmol for SNAP-8.
How many mg of SNAP-8 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 SNAP-8 (MW 1075.2) weighs 0.2393 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of LL-37 and SNAP-8
PubChem lists LL-37 as C205H340N60O53 (4493 g/mol) and SNAP-8 as C41H70N16O16S (1075.2 g/mol). LL-37 is a peptide; SNAP-8 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 SNAP-8 in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 2.393 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 SNAP-8 in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of SNAP-8 (MW 1075.2) would weigh 1.197 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of SNAP-8 equals how many mg of LL-37 in moles?
5 mg of SNAP-8 (MW 1075.2) is 4.65 µmol. The same amount of LL-37 (MW 4493) would weigh 20.894 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of SNAP-8 equals how many mg of LL-37 in moles?
10 mg of SNAP-8 (MW 1075.2) is 9.301 µmol. The same amount of LL-37 (MW 4493) would weigh 41.788 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
