Find and write down structures of 10 interesting small molecular weight biomolecules. Find if there is any industry which manufactures the compounds by isolation. Find out who are the buyers.
Based on the provided context, small molecular weight biomolecules (micromolecules) are compounds with molecular weights less than one thousand daltons, typically ranging from 18 to around 800 daltons.
Examples mentioned in the context include:
- Amino acids
- Sugars
Additionally, the context lists secondary metabolites which are found in plant, fungal and microbial cells: 3. Alkaloids 4. Flavonoids 5. Rubber 6. Essential oils 7. Antibiotics 8. Coloured pigments 9. Scents 10. Gums 11. Spices
Regarding isolation: The context states that one can extract compounds from living tissues and subject the extract to various separation techniques to isolate and purify a compound. Analytical techniques then give information about molecular formula and probable structure.
Regarding industries and buyers: The provided context does not contain specific information about which industries manufacture these compounds by isolation or who the buyers are. This would require additional research beyond the given textbook content.
Explanation
The question asks for structures of 10 biomolecules, industries manufacturing them, and buyers. However, the provided context only gives general categories of small molecular weight biomolecules (amino acids, sugars) and secondary metabolites (alkaloids, flavonoids, rubber, essential oils, antibiotics, coloured pigments, scents, gums, spices). The context mentions the process of isolation from living tissues but does NOT provide: (1) specific molecular structures, (2) names of industries that manufacture these compounds, or (3) information about buyers. This appears to be a research-based activity question in the NCERT textbook that requires students to investigate beyond the chapter content.
Solution Steps
Step 1: Identify that small molecular weight biomolecules have molecular weights less than 1000 daltons (18-800 Da range).
Step 2: List primary metabolites mentioned: amino acids, sugars.
Step 3: List secondary metabolites mentioned: alkaloids, flavonoids, rubber, essential oils, antibiotics, coloured pigments, scents, gums, spices.
Step 4: Note that context describes isolation process but lacks specific industry/buyer information.
