amino acid的音標(biāo)為[e"mini ɑ:s] ，基本翻譯為“氨基酸”，速記技巧為：amin-o-sulf-o-cys-o-peptide。

Amino acid這個(gè)詞源自希臘語詞根amino，意為“氨基酸”，是構(gòu)成蛋白質(zhì)的基本單位。這個(gè)詞的變化形式包括其過去式amino和過去分詞amninated。相關(guān)單詞包括：

1. protein：蛋白質(zhì)，這個(gè)詞源自拉丁語，意為“主要的”，指代氨基酸的主要成分。

2. amino：前綴amino-來自希臘語amino，意為“氨基酸”，這個(gè)詞常用于合成詞中，如animal amino acid（動(dòng)物氨基酸）。

3. peptone： pept- 來自希臘語pepsi，意為“分解”，-one表示物質(zhì)，所以peptone意為“蛋白胨”，是一種常用的氮源。

4. amino acid solution：氨基酸溶液，其中-tion是名詞后綴，表示物質(zhì)或狀態(tài)。

5. amino acid deficiency：氨基酸缺乏癥，de- 表示“缺乏”，-ficiency表示狀態(tài)。

6. amino acid transporter：氨基酸轉(zhuǎn)運(yùn)蛋白，transporter表示“運(yùn)輸者”。

7. amino acid analysis：氨基酸分析，-tion表示動(dòng)作或狀態(tài)。

8. amino acid metabolism：氨基酸代謝，-logy表示學(xué)科。

9. amino acid synthesis：氨基酸合成，syn- 表示“合成”，-thesis表示動(dòng)作。

10. amino acid degradation：氨基酸降解，degrad- 表示“分解”，-ation表示動(dòng)作或狀態(tài)。

以上就是關(guān)于氨基酸及其相關(guān)詞匯的一些英文詞源、變化形式和相關(guān)單詞的解釋。氨基酸在生物體內(nèi)起著至關(guān)重要的作用，是構(gòu)成生命物質(zhì)和酶的重要成分。
