What is the difference between Matrixyl and TB-500?

Matrixyl is a palmitoylated pentapeptide derived from a procollagen I fragment, widely studied in cosmetic-science and fibroblast-culture research (lipopeptide, MW about 802.1 g/mol).

Which is heavier, Matrixyl or TB-500?

Matrixyl has a molecular weight of about 802.1 g/mol and TB-500 about 889 g/mol (PubChem), so TB-500 is heavier by 86.9 g/mol, a ratio of 1.11. This means 1 mg of Matrixyl contains 1,246.7 nmol versus 1,124.9 nmol for TB-500.

How many mg of TB-500 are equimolar to 1 mg of Matrixyl?

1 mg of Matrixyl (MW 802.1) is 1,246.7 nmol. The same number of moles of TB-500 (MW 889) weighs 1.108 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Matrixyl and TB-500

PubChem lists Matrixyl as C39H75N7O10 (802.1 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). Matrixyl is a lipopeptide; TB-500 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
