4 syllables: De, hy, dra, se. Stress on hy.
dee-HEYE-drayz
/diˈhaɪdreɪz/
Dehydrase is pronounced dee-HEYE-drayz (/diˈhaɪdreɪz/). It has four syllables (De-hy-dra-se), with the stress on "hy". Dehydrase is a biological enzyme that catalyzes the removal of water from a substrate as part of metabolic processes. It is typically used to describe a class of enzymes that facilitate dehydration reactions, often in biochemical pathways. In expert usage, it denotes a specific catalytic function and is encountered in scientific literature and enzyme nomenclature.

- You might misplace the stress on the first syllable (de-HY-draze). To fix, remind yourself that the main energy sits on the second syllable: de-HY-draze, not de-HYd-RAZE. - Mispronounce the 'hy' as a soft 'hye' or blur the 'dray' into 'dra' by using a weak /eɪ/; practice with the exact /aɪ/ diphthong followed by /dreɪz/. - Final consonant: avoid turning the final /z/ into /s/ or a voiced/unvoiced mismatch; ensure voicing and placement at the tip of the tongue behind the upper teeth; keep vibration continuous.
"The dehydrase accelerates the dehydration step in the metabolic pathway."
"Researchers measured the activity of the dehydrase under varying pH levels."
"Mutations in the dehydrase gene impaired the organism’s ability to process the substrate."
Pronounce as /dɪˈhaɪ.dreɪz/ in US and UK contexts, with the primary stress on the second syllable. The first syllable 'de-' is short, the second 'hy-' bears the main stress, and the final '-rase' sounds like 'rays' in most dialects. For American English, you can emphasize the 'ɪ' in 'de' lightly and then clearly pronounce 'HY-dreɪz' with a long 'a' in 'drayz'. See audio references in Pronounce or Forvo for modeling.
Common errors include misplacing stress on the first syllable (dɪ-HAI-dreɪz) and mispronouncing the second syllable as 'hy-draze' with a long 'a' that collapses the 're' vowel. A precise correction is to keep the secondary syllable unstressed and deliver 'HY' as a distinct compressed onset, then finish with 'dreɪz'—avoid turning it into 'hydr-ahze' or 'deh-yd-raz'.
In US and UK accents, the 'hyd' portion produces a clear long 'i' in 'haɪ' and the suffix '-rase' tends to be 'reɪz'. Rhotic influence may subtly color the initial vowel in non-rhotic UK accents, but the main stress remains on the second syllable. Australian pronunciation aligns with non-rhotic tendencies, with crisp 'drayz' and high front vowel in 'haɪ'. Overall, the difference is minor; focus on vowel quality and final '-z'.
The challenge lies in the two-syllable structure with a stressed second syllable and the combination 'hy' followed by 'dreɪz'. The 'h' is not silent, and the 'ai' yields a tense diphthong /aɪ/. Also, the final /z/ must be voiced, not a /s/. Practice the transition between /ˈhaɪ/ and /dreɪz/ to avoid a clipped or swallowed middle bit.
Note the internal syllable boundary: de-HY-draze; the primary stress lands on the second syllable 'HY'. The 'de' prefix is unstressed; keep it light, but the 'HY' should be crisp and higher in pitch. Don’t merge the vowels across syllables; maintain a clean break between the 'hy' and 'draze' to preserve syllable clarity.

- US: emphasize rhotics lightly, keep /ɪ/ in the first syllable short, /ˈhaɪ/ with a clear diphthong and a strong /d/ onset. - UK: non-rhotic; ensure the /r/ is not pronounced; keep /ˈhaɪ.dreɪz/ with crisp /d/ and clear /eɪ/ in the suffix. - AU: similar to US/UK but with flatter intonation; keep the same vowel qualities but watch for broader vowel shifts in /aɪ/ and a slightly longer final /z/.
Dehydrase derives from the Latin 'de-' meaning removal and the Greek 'hydra' meaning water, combined with the suffix '-ase' used in biochemistry to denote an enzyme. The term surfaces in the 20th century amid rapid expansion of enzymology, as researchers labeled enzymes by their catalytic reaction. Early usage followed the broader class-naming pattern (e.g., dehydratase, hydrolase), with dehydration-focused enzymes distinguished when their primary function is removing water molecules from substrates. The root 'dehydrate' itself appears in English from the 16th century, originally describing the removal of water from foods, air, or tissues, before being specialized to chemistry and biochemistry. The '-ase' suffix was established in the 19th century through the work of biochemical nomenclature committees and became standard for enzyme names. First known uses often appear in biochemistry texts and enzymology papers that describe dehydration reactions in metabolism, polysaccharide modification, and nucleotide chemistry. Over time, 'dehydrase' became a precise, though less common, descriptor used to name specific enzymes that catalyze water removal steps, distinct from general dehydration processes. Modern usage tends toward technical contexts, where the exact substrate and reaction type are defined in a research article.”,
