What is the difference between LL-37 and Vilon?
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 Vilon?
LL-37 has a molecular weight of about 4493 g/mol and Vilon about 275.3 g/mol (PubChem), so LL-37 is heavier by 4,217.7 g/mol, a ratio of 16.32. This means 1 mg of LL-37 contains 222.6 nmol versus 3,632.4 nmol for Vilon.
How many mg of Vilon 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 Vilon (MW 275.3) weighs 0.06127 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of LL-37 and Vilon
PubChem lists LL-37 as C205H340N60O53 (4493 g/mol) and Vilon as C11H21N3O5 (275.3 g/mol). LL-37 is a peptide; Vilon is a dipeptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of LL-37 equals how many mg of Vilon in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of Vilon (MW 275.3) would weigh 0.6127 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 Vilon in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of Vilon (MW 275.3) would weigh 0.3064 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Vilon equals how many mg of LL-37 in moles?
10 mg of Vilon (MW 275.3) is 36.324 µmol. The same amount of LL-37 (MW 4493) would weigh 163.2 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Vilon equals how many mg of LL-37 in moles?
20 mg of Vilon (MW 275.3) is 72.648 µmol. The same amount of LL-37 (MW 4493) would weigh 326.4 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
