What is the difference between Kisspeptin-10 and PT-141?
Kisspeptin-10 is the C-terminal decapeptide of kisspeptin, used as a KISS1R (GPR54) agonist in reproductive neuroendocrinology research (peptide, MW about 1302.4 g/mol).
Which is heavier, Kisspeptin-10 or PT-141?
Kisspeptin-10 has a molecular weight of about 1302.4 g/mol and PT-141 about 1025.2 g/mol (PubChem), so Kisspeptin-10 is heavier by 277.2 g/mol, a ratio of 1.27. This means 1 mg of Kisspeptin-10 contains 767.8 nmol versus 975.4 nmol for PT-141.
How many mg of PT-141 are equimolar to 1 mg of Kisspeptin-10?
1 mg of Kisspeptin-10 (MW 1302.4) is 767.8 nmol. The same number of moles of PT-141 (MW 1025.2) weighs 0.7872 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Kisspeptin-10 and PT-141
PubChem lists Kisspeptin-10 as C63H83N17O14 (1302.4 g/mol) and PT-141 as C50H68N14O10 (1025.2 g/mol). Kisspeptin-10 is a peptide; PT-141 is a cyclic peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of Kisspeptin-10 equals how many mg of PT-141 in moles?
5 mg of Kisspeptin-10 (MW 1302.4) is 3.839 µmol. The same amount of PT-141 (MW 1025.2) would weigh 3.936 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Kisspeptin-10 equals how many mg of PT-141 in moles?
10 mg of Kisspeptin-10 (MW 1302.4) is 7.678 µmol. The same amount of PT-141 (MW 1025.2) would weigh 7.872 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of PT-141 equals how many mg of Kisspeptin-10 in moles?
10 mg of PT-141 (MW 1025.2) is 9.754 µmol. The same amount of Kisspeptin-10 (MW 1302.4) would weigh 12.704 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of PT-141 equals how many mg of Kisspeptin-10 in moles?
5 mg of PT-141 (MW 1025.2) is 4.877 µmol. The same amount of Kisspeptin-10 (MW 1302.4) would weigh 6.352 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
