What is the difference between LL-37 and Cartalax?
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 Cartalax?
LL-37 has a molecular weight of about 4493 g/mol and Cartalax about 333.29 g/mol (PubChem), so LL-37 is heavier by 4,159.7 g/mol, a ratio of 13.48. This means 1 mg of LL-37 contains 222.6 nmol versus 3,000.4 nmol for Cartalax.
How many mg of Cartalax 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 Cartalax (MW 333.29) weighs 0.07418 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of LL-37 and Cartalax
PubChem lists LL-37 as C205H340N60O53 (4493 g/mol) and Cartalax as C12H19N3O8 (333.29 g/mol). LL-37 is a peptide; Cartalax is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Cartalax equals how many mg of LL-37 in moles?
10 mg of Cartalax (MW 333.29) is 30.004 µmol. The same amount of LL-37 (MW 4493) would weigh 134.8 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Cartalax equals how many mg of LL-37 in moles?
20 mg of Cartalax (MW 333.29) is 60.008 µmol. The same amount of LL-37 (MW 4493) would weigh 269.6 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 Cartalax in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of Cartalax (MW 333.29) would weigh 0.7418 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 Cartalax in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of Cartalax (MW 333.29) would weigh 0.3709 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
