5 syllables: Hy, droxy, bu, ty, rate. Stress on Hy.
HEYE-drok-see-byoo-tuh-rayt
/ˈhaɪdɹɒksiˌbjuːtəreɪt/
Hydroxybutyrate is pronounced HEYE-drok-see-byoo-tuh-rayt (/ˈhaɪdɹɒksiˌbjuːtəreɪt/). It has five syllables (Hy-droxy-bu-ty-rate), with the stress on "Hy". As a noun, a chemical term for a salt or ester of hydroxybutyric acid, typically used in biochemistry and medicine. It denotes a compound containing a hydroxy group and a butyrate moiety bound together, often as an intermediate or metabolite. In context, it refers to specific hydroxy-substituted butyrates involved in metabolic pathways or pharmaceutical formulations.

How to Pronounce Hydroxybutyrate
"The enzyme converts hydroxybutyrate into another intermediate in the pathway."
"Researchers measured hydroxybutyrate levels in the patient’s blood to assess metabolism."
"Hydroxybutyrate esters are used as prodrugs to improve solubility and delivery."
Pronounce as hy-DROH-xy-BY-tryate, with primary stress on the BY syllable after the initial HY- and a secondary stress? notate as /ˌhaɪdroʊˈbaɪtəˌreɪt/ for US. Break down: HY-drox-y (three segments), BYE-tuh-rate. Tip: emphasize the “BY” as a strong syllable, keep the final -ate as -ate (reɪt) rather than -et.
Common errors: (1) Misplacing the stress, saying HY-droxy-BYU-riate; (2) Slurring the -ate into -et or -eat; (3) Mispronouncing the ‘xy’ as “zai” or shortening it. Correction: keep three phonetic chunks HY-drox-y-BY-ti-rate; articulate the -y- as a separate vowel /ɪ/ or /aɪ/ depending on segment, and finish with /reɪt/. Practice by chunking into syllables HY-drox-y by-TRY-ate and matching IPA.
US: /ˌhaɪdroʊˈbaɪtərˌeɪt/ with rhotic r and clear /oʊ/. UK: /ˌhaɪdrəʊˈbaɪtəˌreɪt/ with nonrhotic /r/ and more centralized /əʊ/. AU: /ˌhaɪdrɒˈbaɪtəˌreɪt/ features broad /ɒ/ and broader Australian vowel length; rhotics vary with speaker. In all, stress remains on the BY syllable block, but vowels shift per accent.
Because it combines a multisyllabic root (hydroxy-), a less common -oy- sequence, and a -ate ending with two separate vowel sounds. The sequence HY-droxy-BY-ty-rate requires accurate vowel placement and sustained jaw movement. The presence of the diphthong in /oʊ/ and the /aɪ/ in /baɪ/ increases precision demands, and maintaining the -er- vs -re- distinction in fast speech can lead to mispronunciation.
The emphasis on the BY syllable and the pronounced -t- before -ate can tempt you to reduce the middle syllable. Focus on keeping the /t/ clear and separating the /tə/ from /eɪt/. Also ensure the initial HY- isn't reduced: keep the /haɪ/ as a clear diphthong and avoid a schwa reduction in the first syllable. IPA cues: /ˌhaɪdroʊˈbaɪtərˌeɪt/.

Hydroxybutyrate is built from three morphemes: hydroxy- (from Greek hydro, water, and xys, sharp/sour, later assigned as a chemical hydroxy group), butyr- (from butyric acid, derived from French butyre, itself from Latin butyrum, meaning butter), and -ate (a suffix used in chemistry to indicate a salt or ester of an acid). The term first appears in late 19th to early 20th century biochemical literature as researchers described derivatives of butyric acid with hydroxyl substitutions. The modern usage centers on compounds that are esters or salts of hydroxy-substituted butyric acid; in practice, the precise placement and number of hydroxyl groups define the exact hydroxybutyrate isomer (e.g., 3-hydroxybutyrate). The etymology reflects the systematic naming adopted during the expansion of organic chemistry and metabolic biochemistry, paralleling the growth of the coenzyme and metabolite lexicon as metabolic pathways were elucidated. First known uses occur in biochemistry texts when new intermediates in fatty acid metabolism were being characterized, with the modern form solidifying through the mid-20th century alongside advances in analytical methods like chromatography and mass spectrometry.
