Zein, a special kind of protein is obtained from:
Show Hint
- Storage protein in maize endosperm.
- Used in biodegradable plastics, coatings, and films.
- Rich in glutamic acid and leucine.
- Ramie (Bohemeria nivea)
- Guar (Cyanopsis tetragonoloba)
- Grass pea (Lathyrus sativus)
- Maize (Zea mays)
The Correct Option is D
Solution and Explanation
This question tests knowledge of the source of the protein zein.
Step 2: Detailed Explanation:
Zein is a type of protein (prolamin) that is obtained from maize (Zea mays).
It is a storage protein found in the endosperm of maize kernels.
Zein is used in various industrial applications, including biodegradable plastics and coatings.
Other options:
- Ramie (A): A bast fibre plant.
- Guar (B): Source of guar gum (a polysaccharide).
- Grass pea (C): Contains neurotoxin (ODAP) and is not a source of zein.
Thus, zein is obtained from maize.
Step 3: Final Answer:
Thus, zein is obtained from maize, which corresponds to option (D).
