What is the difference between KPV and LL-37?
KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone, studied in inflammation-signalling research in cell and rodent models (peptide, MW about 342.43 g/mol).
Which is heavier, KPV or LL-37?
KPV has a molecular weight of about 342.43 g/mol and LL-37 about 4493 g/mol (PubChem), so LL-37 is heavier by 4,150.6 g/mol, a ratio of 13.12. This means 1 mg of KPV contains 2,920.3 nmol versus 222.6 nmol for LL-37.
How many mg of LL-37 are equimolar to 1 mg of KPV?
1 mg of KPV (MW 342.43) is 2,920.3 nmol. The same number of moles of LL-37 (MW 4493) weighs 13.121 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of KPV and LL-37
PubChem lists KPV as C16H30N4O4 (342.43 g/mol) and LL-37 as C205H340N60O53 (4493 g/mol). KPV is a peptide; LL-37 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 2 mg vial of KPV equals how many mg of LL-37 in moles?
2 mg of KPV (MW 342.43) is 5.841 µmol. The same amount of LL-37 (MW 4493) would weigh 26.242 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of KPV equals how many mg of LL-37 in moles?
5 mg of KPV (MW 342.43) is 14.602 µmol. The same amount of LL-37 (MW 4493) would weigh 65.605 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of KPV equals how many mg of LL-37 in moles?
10 mg of KPV (MW 342.43) is 29.203 µmol. The same amount of LL-37 (MW 4493) would weigh 131.2 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of KPV equals how many mg of LL-37 in moles?
20 mg of KPV (MW 342.43) is 58.406 µmol. The same amount of LL-37 (MW 4493) would weigh 262.4 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 KPV in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of KPV (MW 342.43) would weigh 0.7621 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 KPV in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of KPV (MW 342.43) would weigh 0.3811 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
