CATTI二級筆譯日常練習(xí)：生命與蛋白質(zhì)的關(guān)系

CATTI是學(xué)英語人的一塊試金石，平時(shí)都覺得自己英語學(xué)的還行，試過CATTI就知道自己是什么水平了。這里還是建議大家實(shí)踐為主，因?yàn)榉g這種東西，經(jīng)驗(yàn)和技巧太重要了。下面是小編整理的關(guān)于CATTI二級筆譯日常練習(xí)：生命與蛋白質(zhì)的關(guān)系的內(nèi)容，希望對你有所幫助！

　　英文：

　　TO UNDERSTAND LIFE, you must understand proteins. These molecular chains, each assembled from a menu of 20 types of chemical links called amino acids, do biology’s heavy lifting. In the guise of enzymes they catalyse the chemistry that keeps bodies running. Actin and myosin, the proteins of muscles, permit those bodies to move around. Keratin provides their skin and hair. Haemoglobin carries their oxygen. Insulin regulates their metabolism. And a protein called spike allows coronaviruses to invade human cells, thereby shutting down entire economies. Listing a protein’s amino acids is easy. Machines to do so have existed for decades. But this is only half the battle in the quest to understand how proteins work. What a protein does, and how it does it, depends also on how it folds up after its creation, into its final, intricate shape.

　　參考譯文：

　　要了解生命，必須了解蛋白質(zhì)。這些分子鏈每條都由總共20種稱為氨基酸的化學(xué)鏈中的某些連接組成，擔(dān)負(fù)著大量的生理功能。它們以酶的形式催化著使身體保持運(yùn)轉(zhuǎn)的化學(xué)反應(yīng)。肌肉中的肌動(dòng)蛋白和肌球蛋白讓身體可以自由活動(dòng)。角蛋白是皮膚和頭發(fā)的主要成分。血紅蛋白攜帶氧氣。胰島素調(diào)節(jié)身體的新陳代謝。而一種叫做刺突的蛋白質(zhì)讓冠狀病毒得以入侵人體細(xì)胞，最終令整個(gè)國家停擺。列出組成一種蛋白質(zhì)的氨基酸很容易。具備這種功能的機(jī)器已經(jīng)發(fā)明幾十年了。但要了解蛋白質(zhì)的作用機(jī)制，列出氨基酸只是完成了工作的一半。一種蛋白質(zhì)的作用及其作用機(jī)制還取決于蛋白質(zhì)在生成后如何折疊成最終的復(fù)雜形狀。

以上就是小編整理的關(guān)于CATTI二級筆譯日常練習(xí)：生命與蛋白質(zhì)的關(guān)系的內(nèi)容，大家切記要經(jīng)常動(dòng)手翻譯，堅(jiān)持一段時(shí)間，一定會(huì)獲益頗豐！
