What is the difference between LL-37 and Matrixyl?
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 Matrixyl?
LL-37 has a molecular weight of about 4493 g/mol and Matrixyl about 802.1 g/mol (PubChem), so LL-37 is heavier by 3,690.9 g/mol, a ratio of 5.6. This means 1 mg of LL-37 contains 222.6 nmol versus 1,246.7 nmol for Matrixyl.
How many mg of Matrixyl 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 Matrixyl (MW 802.1) weighs 0.1785 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of LL-37 and Matrixyl
PubChem lists LL-37 as C205H340N60O53 (4493 g/mol) and Matrixyl as C39H75N7O10 (802.1 g/mol). LL-37 is a peptide; Matrixyl is a lipopeptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of LL-37 equals how many mg of Matrixyl in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of Matrixyl (MW 802.1) would weigh 1.785 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 Matrixyl in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of Matrixyl (MW 802.1) would weigh 0.8926 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Matrixyl equals how many mg of LL-37 in moles?
5 mg of Matrixyl (MW 802.1) is 6.234 µmol. The same amount of LL-37 (MW 4493) would weigh 28.008 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Matrixyl equals how many mg of LL-37 in moles?
10 mg of Matrixyl (MW 802.1) is 12.467 µmol. The same amount of LL-37 (MW 4493) would weigh 56.015 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
