What is the difference between KPV and TB-500?
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 TB-500?
KPV has a molecular weight of about 342.43 g/mol and TB-500 about 889 g/mol (PubChem), so TB-500 is heavier by 546.6 g/mol, a ratio of 2.6. This means 1 mg of KPV contains 2,920.3 nmol versus 1,124.9 nmol for TB-500.
How many mg of TB-500 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 TB-500 (MW 889) weighs 2.596 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of KPV and TB-500
PubChem lists KPV as C16H30N4O4 (342.43 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). KPV is a peptide; TB-500 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
