Card 1Introduction to biomolecules

What are biomolecules?

Answer

Biomolecules are carbon compounds found in living tissues. They include small molecules such as amino acids, sugars, fatty acids, nucleotides, and larger molecules such as proteins, nucleic acids, and

Card 2जैव-अणुओं का परिचय

जैव अणु क्या होते हैं?

Answer

जैव-अणु (Biomolecules) कार्बन के यौगिक होते हैं जो जीवित ऊतकों में पाये जाते हैं। इनमें अमीनो अम्ल, शर्करा, वसा अम्ल, न्यूक्लियोटाइड जैसे छोटे अणु और प्रोटीन, न्यूक्लिक अम्ल, पॉलीसैकराइड जैसे बड़े अणु

Card 3Chemical composition of living matter

Why is carbon especially important in living organisms?

Answer

Carbon and hydrogen are relatively more abundant in living organisms than in earth's crust. Carbon forms a wide variety of compounds, which is why living systems show such chemical diversity.

Card 4जीवित पदार्थ की रासायनिक संरचना

कार्बन जीवित जीवों में विशेष रूप से क्यों महत्वपूर्ण है?

Answer

कार्बन और हाइड्रोजन जीवित जीवों में पृथ्वी के भूपर्पटी की तुलना में अपेक्षाकृत अधिक मात्रा में पाए जाते हैं। कार्बन से कई प्रकार के यौगिक बनते हैं, जिस कारण से जीवित प्रणालियाँ इतनी रासायनिक विविधता प

Card 5Chemical analysis of tissues

What is the acid-soluble pool?

Answer

The acid-soluble pool is the filtrate obtained after grinding tissue in trichloroacetic acid and filtering it. It contains micromolecules, usually with molecular weights from 18 to around 800 daltons.

Card 6ऊतकों का रासायनिक विश्लेषण

अम्ल-घुलनशील पूल क्या है?

Answer

अम्ल-विलेय पूल (acid-soluble pool) वह निस्यंद है जो ट्राइक्लोरोएसिटिक अम्ल में ऊतक को पीसकर और छानकर प्राप्त किया जाता है। इसमें सूक्ष्म अणु होते हैं, जिनका अणुभार प्रायः 18 से लेकर लगभग 800 डाल्टन तक

Card 7Biomacromolecules

What is the acid-insoluble fraction?

Answer

The acid-insoluble fraction is the retentate left after filtering the tissue extract. It contains macromolecules such as proteins, nucleic acids, polysaccharides, and lipids. Most of these have molecu

Card 8जैव-बृहदणु

अम्ल-अविलेय अंश क्या है?

Answer

अम्ल में अविलेय अंश ऊतक के रस को छानने के बाद बचा हुआ अवशिष्ट है। इसमें प्रोटीन, न्यूक्लिक अम्ल, पॉलीसैकराइड और लिपिड जैसे मैक्रोमोलेक्यूल्स होते हैं। इनमें से अधिकांश का आणविक भार दस हजार डाल्टन और उ
