Q1. Which one of the following is a fibrous protein?
निम्नलिखित में से कौन-सी एक रेशेदार (तंतुमय) प्रोटीन है?
- A. Serum albumin / सीरम ऐल्ब्यूमिन
- B. Insulin / इंसुलिन
- C. Collagen / कोलैजन
- D. Haemoglobin / हीमोग्लोबिन
Solution
Collagen is a fibrous (structural) protein with polypeptide chains arranged as elongated fibres; insulin, albumin and haemoglobin are globular proteins.
कोलैजन एक रेशेदार (संरचनात्मक) प्रोटीन है जिसकी पॉलीपेप्टाइड श्रृंखलाएँ लंबे तंतुओं के रूप में व्यवस्थित होती हैं; इंसुलिन, ऐल्ब्यूमिन और हीमोग्लोबिन गोलिकाकार प्रोटीन हैं।
Q2. The number of standard α-amino acids from which the proteins of living organisms are commonly built is:
जीवित जीवों की प्रोटीनें सामान्यतः जितने मानक α-ऐमीनो अम्लों से बनी होती हैं, उनकी संख्या है:
- A. 20
- B. 16
- C. 10
- D. 24
Solution
Proteins are synthesised from a common set of 20 standard α-amino acids, of which some are essential and must be obtained from the diet.
प्रोटीनों का संश्लेषण 20 मानक α-ऐमीनो अम्लों के एक सामान्य समुच्चय से होता है, जिनमें से कुछ आवश्यक हैं और आहार से प्राप्त करने पड़ते हैं।
Q3. In sucrose, the glycosidic linkage joins:
सुक्रोज़ में ग्लाइकोसाइडिक बंध जोड़ता है:
- A. C1 of β-fructose and C4 of α-glucose / β-फ्रक्टोज़ का C1 और α-ग्लूकोज़ का C4
- B. C1 of α-glucose and C2 of β-fructose / α-ग्लूकोज़ का C1 और β-फ्रक्टोज़ का C2
- C. C1 of β-galactose and C4 of β-glucose / β-गैलेक्टोज़ का C1 और β-ग्लूकोज़ का C4
- D. C1 of α-glucose and C4 of α-glucose / α-ग्लूकोज़ का C1 और α-ग्लूकोज़ का C4
Solution
Sucrose is formed by linkage of C1 of α-D-glucose with C2 of β-D-fructose; because both anomeric carbons are involved, no free reducing group remains and sucrose is a non-reducing sugar.
सुक्रोज़ α-D-ग्लूकोज़ के C1 तथा β-D-फ्रक्टोज़ के C2 के बंधन से बनता है; चूँकि दोनों एनोमेरिक कार्बन सम्मिलित हैं, कोई मुक्त अपचायी समूह शेष नहीं रहता और सुक्रोज़ एक अनपचायी शर्करा है।
