Students use sds‐page standard protein mobilities to prepare a calibration curve to determine molecular weights they compare their mb molecular weight to the literature value, and also establish the fraction of mb in their samples. The monomers are of molecular weight (16-17)x 103 however, another molecule, a monomeric oxygen-binding globin called tissue hemoglobin or myoglobin, is found in heart and red skeletal muscle cells. The average molecular weight of an amino acid is about 110, so you would expect the whole molecule to weigh around 17,000 amu (or daltons) 16,426 g/mol seems like a lot, but remember, this is not oxygen or cyclohexane, this is a huge molecule with at least 153 nitrogens and oxygens and many more carbons and hydrogens.
