Multiple Choice Question
Which of the following standard amino acids contains a secondary amine (imino) group rather than a primary amine, giving its side chain a rigid, cyclic structure?निम्नलिखित में से किस मानक अमीनो एसिड में प्राथमिक अमीन के बजाय द्वितीयक अमीन (imino) समूह होता है, जो इसके साइड चेन को एक कठोर, चक्रीय संरचना देता है?
Explanation:
Proline is unique among the 20 standard amino acids because its side chain is cyclized to the backbone nitrogen, making it an alpha-imino acid and causing kinks in protein helices.
प्रोलाइन अद्वितीय है क्योंकि इसकी साइड चेन बैकबोन नाइट्रोजन से जुड़ी (cyclized) होती है, जिससे यह एक अल्फा-इमिनो एसिड बन जाता है और प्रोटीन हेलिक्स में रुकावट पैदा करता है।
