poly-意为“多”，peptide是“肽”，联想多个氨基酸手拉手串成一长链，就是polypeptide多肽。
Context & Register
语域：formal 常见场景：academic papers、biochemistry textbooks、laboratory reports polypeptide 是生物化学中的专业词，多用于学术论文、教科书和实验室报告等正式场合；日常对话中较少见，通常可译为“多肽”。
Pronunciation & Spelling
polypeptide 读 /ˌpɒliˈpeptaɪd/，重音在 -pep-。真正押韵的是 peptide（/ˈpeptaɪd/）。nucleotide 虽以 -tide 结尾，但重音在第一个音节，不押韵；chloride、cyanide、oxide、sulfide 只共享拼写 -ide（读 /aɪd/），重音和元音都不同，也不押韵。
