What is the difference between GHRP-2 and MOTS-c?
GHRP-2 is a synthetic growth hormone secretagogue hexapeptide studied as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 818 g/mol).
Which is heavier, GHRP-2 or MOTS-c?
GHRP-2 has a molecular weight of about 818 g/mol and MOTS-c about 2174.6 g/mol (PubChem), so MOTS-c is heavier by 1,356.6 g/mol, a ratio of 2.66. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 459.9 nmol for MOTS-c.
How many mg of MOTS-c are equimolar to 1 mg of GHRP-2?
1 mg of GHRP-2 (MW 818) is 1,222.5 nmol. The same number of moles of MOTS-c (MW 2174.6) weighs 2.658 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-2 and MOTS-c
PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and MOTS-c as C101H152N28O22S2 (2174.6 g/mol). GHRP-2 is a peptide; MOTS-c is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-2 equals how many mg of MOTS-c in moles?
5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of MOTS-c (MW 2174.6) would weigh 13.292 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-2 equals how many mg of MOTS-c in moles?
10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of MOTS-c (MW 2174.6) would weigh 26.584 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of MOTS-c equals how many mg of GHRP-2 in moles?
5 mg of MOTS-c (MW 2174.6) is 2.299 µmol. The same amount of GHRP-2 (MW 818) would weigh 1.881 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of MOTS-c equals how many mg of GHRP-2 in moles?
10 mg of MOTS-c (MW 2174.6) is 4.599 µmol. The same amount of GHRP-2 (MW 818) would weigh 3.762 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of MOTS-c equals how many mg of GHRP-2 in moles?
20 mg of MOTS-c (MW 2174.6) is 9.197 µmol. The same amount of GHRP-2 (MW 818) would weigh 7.523 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of MOTS-c equals how many mg of GHRP-2 in moles?
30 mg of MOTS-c (MW 2174.6) is 13.796 µmol. The same amount of GHRP-2 (MW 818) would weigh 11.285 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 40 mg vial of MOTS-c equals how many mg of GHRP-2 in moles?
40 mg of MOTS-c (MW 2174.6) is 18.394 µmol. The same amount of GHRP-2 (MW 818) would weigh 15.046 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
