/ˌpɹoʊtiˈlɪtɪk/
Proteolytic is pronounced proh-tee-LIT-ik (/ˌpɹoʊtiˈlɪtɪk/). It has four syllables (Pro-te-ol-ytic), with the stress on "ytic". Proteolytic is an adjective describing enzymes or processes that break down proteins by hydrolyzing peptide bonds. It is mainly used in biochemistry and physiology to refer to proteases and related activities. The term emphasizes the action of digestion of proteins at the molecular level, often in digestion, digestion-like experiments, or proteolysis pathways.

"The proteolytic activity of the enzyme released peptides from the substrate."
"Researchers measured proteolytic cleavage to map protein domains."

Pronounce as proh-TEE-ohl-ih-tik with the primary stress on the TEA- syllable cluster (the -ol- part). IPA: US ˌproʊtiˈɒlɪtɪk, UK ˌprəʊtiˈɒlɪtɪk, AU ˌprəʊtiˈɒlɪtɪk. Start with PROH or PRO
Common mistakes include stressing the wrong syllable (placing primary stress on the -li- rather than -ol-), neutralizing the vowel sequence in 'pro' to a quick 'proh' vs 'proh-TEO-','and mispronouncing the 'ol' as a short 'ol' rather than a clear 'oh' as in 'ol' diphthong. To correct: emphasize the -TEO- syllable with a clear long 'ō' sound, pronounce the 'ol' as /ɒl/ in UK or /ɑl/ in US, and keep the final -tɪk crisp.
In US, you’ll hear /ˌproʊtiˈɒlɪtɪk/ with a rhotic, and stress on the -ol- syllable; vowels are more rhotic and have a clear 'oh' in /oʊ/. UK pronunciation /ˌprəʊtiˈɒlɪtɪk/ uses a non-rhotic /ˈprəʊ/ with a longer /əʊ/ in the first syllable, and Australian /ˌprəʊtiˈɒlɪtɪk/ resembles UK but with Australian vowel quality. All keep the same stress pattern on the -ol- syllable.
The difficulty stems from the three-syllable rhythm with a mid-stressed -TEO- segment, the combination of 'pro' or 'proh' leading into an unusual /ti/ sequence, and the /ɒl/ vs /lɪ/ vowel shifts across accents. Beginners often miss the long 'o' in -ti- and shorten the final -tɪk. Practice by isolating the -tiɒl- cluster, then blending into the -ɪk ending, ensuring a crisp, alveolar /t/.
A unique feature is the presence of the /tiˈɒl/ sequence where the /t/ is followed by an unstressed /ɪ/ before the final /tɪk/. This can cause a slight reduction or flapping in rapid speech. Emphasize the /tiˈɒl/ segment with careful jaw positioning: tongue tip for /t/, mid-palate contact for /l/, and a short, crisp /t/ before /ɪk/.

Proteolytic derives from the combination of Greek protos (first, primary) and Latin/Greek lysis (loosening, dissolution) with the combining form -lytic from Latin -lyticus, itself from Greek lutikos meaning capable of loosening. The root prote- comes from proteios, meaning taking the first place or protein, and is tied to protein breakdown via proteases. The term proteolysis first appeared in biochemical literature in the early 20th century as scientists studied enzymatic protein digestion. Over time, proteolytic is used to specify enzymes that catalyze proteolysis, such as proteases, peptidases, and proteolytic pathways in digestion, cell turnover, and venom systems. The word integrates a literal sense of breaking proteins apart with the -lytic suffix that denotes dissolution or breakdown; this pattern mirrors other -lytic terms used in medicine and biology. First known usage appears in enzymology literature around the 1940s–1950s as researchers began to categorize enzymes by whether they cleave peptide bonds and by their substrate specificity. The term has since become standard in biochemistry, physiology, pharmacology, and pathology to denote protease-mediated protein degradation processes.
