What is the difference between KPV and Semax?
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 Semax?
KPV has a molecular weight of about 342.43 g/mol and Semax about 813.9 g/mol (PubChem), so Semax is heavier by 471.5 g/mol, a ratio of 2.38. This means 1 mg of KPV contains 2,920.3 nmol versus 1,228.7 nmol for Semax.
How many mg of Semax 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 Semax (MW 813.9) weighs 2.377 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of KPV and Semax
PubChem lists KPV as C16H30N4O4 (342.43 g/mol) and Semax as C37H51N9O10S (813.9 g/mol). KPV is a peptide; Semax 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 Semax in moles?
2 mg of KPV (MW 342.43) is 5.841 µmol. The same amount of Semax (MW 813.9) would weigh 4.754 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 Semax in moles?
5 mg of KPV (MW 342.43) is 14.602 µmol. The same amount of Semax (MW 813.9) would weigh 11.884 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 Semax in moles?
10 mg of KPV (MW 342.43) is 29.203 µmol. The same amount of Semax (MW 813.9) would weigh 23.768 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 Semax in moles?
20 mg of KPV (MW 342.43) is 58.406 µmol. The same amount of Semax (MW 813.9) would weigh 47.537 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Semax equals how many mg of KPV in moles?
5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of KPV (MW 342.43) would weigh 2.104 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Semax equals how many mg of KPV in moles?
10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of KPV (MW 342.43) would weigh 4.207 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of Semax equals how many mg of KPV in moles?
30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of KPV (MW 342.43) would weigh 12.622 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
