Myosin is a 520 kDa hexamer, or a '''hexa-oligomer''' (6 subunit) structure. It is comprised of two heavy chains (weighing 220 kDa each) and 4 light chains (weighing 20 kDa each).<ref name="CHEM43">[http://www.cs.stedwards.edu/chem/Chemistry/CHEM43/CHEM43/Myosin/STRUCT~1.HTM]</ref> | Myosin is a 520 kDa hexamer, or a '''hexa-oligomer''' (6 subunit) structure.
