What is the difference between LL-37 and Semaglutide?
LL-37 is the 37-residue active fragment of the human cathelicidin hCAP18, studied in antimicrobial-peptide and innate-immunity research (peptide, MW about 4493 g/mol).
Which is heavier, LL-37 or Semaglutide?
LL-37 has a molecular weight of about 4493 g/mol and Semaglutide about 4114 g/mol (PubChem), so LL-37 is heavier by 379 g/mol, a ratio of 1.09. This means 1 mg of LL-37 contains 222.6 nmol versus 243.1 nmol for Semaglutide.
How many mg of Semaglutide are equimolar to 1 mg of LL-37?
1 mg of LL-37 (MW 4493) is 222.6 nmol. The same number of moles of Semaglutide (MW 4114) weighs 0.9156 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of LL-37 and Semaglutide
PubChem lists LL-37 as C205H340N60O53 (4493 g/mol) and Semaglutide as C187H291N45O59 (4114 g/mol). LL-37 is a peptide; Semaglutide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
