Explanation / Answer
1. Essential amino acids
since the organism lack the necessary enzymes to synthesize them these essential amino acids need to be supplied through diet/food.
2. Asparagine & Glutamine
These are the polar amino acids with uncharged side chain as they have amide group.
3. Serine & Threonine
These are also polar amino acids with uncharged side chain.
4. Aspartic acid & glutamic acid
These polar amino acids with negatively charged side chain.
5. Fibrous protein
This is the classification based on shape of protein that is fibrous and globular.. Collagen is a fibrous protein
6.Transport protein
This is the classification based on biological function
7. -Keratins. It is classified as Fibrous protein based on shape.
8. b. amide linkages
9. glucosidase enzyme
10. b. zwitterions
11. Glycine
12. Hydrogen bond
