The a few proteins are troponin C, troponin I, and troponin T. Troponin C binds calcium and transports troponin I so muscles can agreement. Troponin T binds troponin proteins to muscle mass fibers.
In individuals with MI, there is a lag just before troponin elevations might be detected.Consequently, the markers need to be serially monitored on suspicion for acute coronary syndrome (ACS).
