Myosin, a proteid substance which occurs in muscle, from which it may be extracted by water and afterwards precipitated by salt. In most of its chemical characters it closely resembles ordinary blood fibrin. It appears to exist in muscle in a dissolved state, and to its coagulation appears to be partly due the phenomenon of rigor mortis or death-stiffening.
