What is the difference between MOTS-c and Selank?
MOTS-c is a 16-residue mitochondrial-derived peptide encoded in the 12S rRNA region, described in 2015 and studied in cellular metabolism research (peptide, MW about 2174.6 g/mol).
Which is heavier, MOTS-c or Selank?
MOTS-c has a molecular weight of about 2174.6 g/mol and Selank about 751.9 g/mol (PubChem), so MOTS-c is heavier by 1,422.7 g/mol, a ratio of 2.89. This means 1 mg of MOTS-c contains 459.9 nmol versus 1,330 nmol for Selank.
How many mg of Selank are equimolar to 1 mg of MOTS-c?
1 mg of MOTS-c (MW 2174.6) is 459.9 nmol. The same number of moles of Selank (MW 751.9) weighs 0.3458 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of MOTS-c and Selank
PubChem lists MOTS-c as C101H152N28O22S2 (2174.6 g/mol) and Selank as C33H57N11O9 (751.9 g/mol). MOTS-c is a peptide; Selank is a peptide. These formulas refer to the parent compounds without salt counter-ions.
