8. Grammatical Role:

"Aminopolypeptidase" primarily functions as a noun. Syllabification and stress remain consistent regardless of grammatical context, as it's not inflected.

9. Definition & Semantics:

• Definition: An enzyme that hydrolyzes peptide bonds in polypeptides, releasing amino acids.
• Grammatical Category: Noun
• Synonyms: Protease, peptidyl hydrolase
• Antonyms: Peptidyl synthetase (enzyme that forms peptide bonds)
• Examples: "The researchers studied the activity of aminopolypeptidase in the cell lysate."

10. Alternative Pronunciations/Regional Variations:

Minor variations in vowel quality (e.g., /æ/ vs. /ɑː/ in "amino-") might occur depending on regional accents within the UK. However, these variations do not significantly alter the syllable division.

11. Phonological Comparison:

• biochemistry: bi-o-chem-is-try - Similar syllable structure, with alternating vowel-consonant patterns.
• pharmacokinetics: phar-ma-co-ki-net-ics - Similar complex compound structure, with stress on the penultimate syllable.
• immunoglobulin: im-mu-no-glob-u-lin - Similar prefix-root-suffix structure, with multiple syllables.

The differences lie in the specific vowel and consonant sequences, but the underlying syllabification principles remain consistent. The length and complexity of "aminopolypeptidase" simply require more application of those principles.
