Morphology
troponin = tropon (opaque) = tropon + in
The combining form 'tropon' is not a common standalone English word and '-in' is a specialized protein suffix, so learners cannot reliably infer the meaning from everyday English vocabulary.
Etymology
Troponin comes from the Greek root tropos meaning 'turn' and the protein ending -in, because troponin helps 'turn' muscle contraction on and off. That's why doctors check troponin in the blood: when the heart muscle is damaged this protein leaks out and shows that the heart may be injured.
