LUV-31 vs MOTS-c
LUV-31 is a 4-residue peptide that starts with a D-arginine, carries a 2',6'-dimethyltyrosine and ends in an amide, while MOTS-c is a 16-residue peptide with no terminal modification recorded.
At ~2,175 g/mol, MOTS-c is more than three times the molecular weight of LUV-31 (unstated).
