IPA: /ˌdɛnəˈtʃʊəreɪʃən/
KK: /dɛnəˈtʃʊrɛɪʃən/
The process in which a protein loses its natural structure due to factors like heat, pH changes, or chemicals, affecting its physical properties.
The denaturation of the protein made it unable to function properly in the experiment.
Denaturation is formed from "de-" (meaning down or away) and "natura" (from Latin, meaning nature). The term describes the process of altering the natural structure of a substance, particularly proteins, by removing its natural qualities.
Think of 'removing' ('de-') the 'natural qualities' ('natura') of a substance — that's what denaturation means.
