Fish proteins are nutritionally superior to most vegetable proteins because they are rich in

Options

A. All the 20 amino acids
B. Essential amino acids
C. Peptide bond
D. Polypeptides.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why fish proteins are considered nutritionally superior to most vegetable proteins.

2. **Identifying Key Terms**: The key terms in the question are "fish proteins," "nutritionally superior," and "vegetable proteins."

3. **Exploring Protein Composition**: Proteins are made up of amino acids. There are 20 different amino acids, but they can be categorized into essential and non-essential amino acids.

4. **Defining Essential Amino Acids**: Essential amino acids are those that cannot be synthesized by the human body and must be obtained through diet. There are nine essential amino acids that humans need.

5. **Comparing Animal and Plant Proteins**: Animal proteins, such as those found in fish, typically contain all essential amino acids in sufficient quantities, making them "complete proteins." In contrast, most plant proteins do not provide all essential amino acids in one source, making them "incomplete proteins."

6. **Conclusion**: Since fish proteins contain all the essential amino acids required by the human body, they are nutritionally superior to most vegetable proteins, which often lack one or more essential amino acids.

7. **Final Answer**: Fish proteins are nutritionally superior to most vegetable proteins because they are rich in **essential amino acids**.
