Question:

Legumes are generally rich in

Show Hint

- Legumes \(\rightarrow\) Globulins (high lysine, low methionine).
- Cereals \(\rightarrow\) Prolamins/Glutelins (low lysine, high methionine).
This complementary relationship is the basis for mixing cereals and pulses in human diets.

The Correct Option is B

Solution and Explanation

Step 1: Understanding the Concept:
Plant seed proteins are classified into four main groups based on their solubility properties:
1. Albumins (soluble in water)
2. Globulins (soluble in dilute salt solutions)
3. Prolamins (soluble in aqueous alcohol)
4. Glutelins (soluble in dilute acids or bases)

Step 3: Detailed Explanation:

- Globulins (B): These are the dominant storage proteins in legume seeds (pulses), accounting for about 70% to 80% of the total seed protein (examples include legumin and vicilin in peas and beans).
- Prolamins (D) and Glutelins (C): These are typically the major storage proteins in cereal grains (e.g., zein in maize, gliadin in wheat, oryzenin in rice).
Hence, legumes are distinctly rich in Globulins.

Step 4: Final Answer:

Legumes are generally rich in Globulins, which corresponds to option (B).
