IPA: //troʊˈpoʊnɪn//
KK: /troʊˈpoʊnɪn/
A type of protein found in muscle tissue that helps control muscle contraction by interacting with calcium ions and other proteins.
Doctors often measure troponin levels in the blood to assess heart damage after a heart attack.
Troponin is derived from the Greek word 'tropos' (meaning turn or change) and 'tonos' (meaning tension or tone). Troponin is a protein complex that plays a crucial role in muscle contraction by regulating the interaction between actin and myosin, thus affecting muscle tone and contraction dynamics.
Think of 'turning' ('tropos') and 'tension' ('tonos') to remember that troponin is involved in regulating muscle contraction and tone.
