Secondary metabolites that belong to lectin is

Options

A. Carotenoids
B. Gums
C. Lemon grass oil
D. Concanavalin A

Answer

**Step-by-Step Solution:**

1. **Understanding Secondary Metabolites**:
- Secondary metabolites are organic compounds that are not directly involved in the normal growth, development, or reproduction of an organism. They are produced in smaller quantities and are often specific to certain plant species.

2. **Characteristics of Secondary Metabolites**:
- They are produced later in the life cycle of the plant.
- They are not essential for basic metabolic processes but can play roles in defense, competition, and attraction of pollinators.
- They are often excreted as waste products but can be beneficial for human use.

3. **Identifying the Group of Interest - Lectins**:
- Lectins are a type of secondary metabolite that can bind to carbohydrates. They are known for their role in plant defense and have applications in biochemistry and medicine.

4. **Example of a Lectin**:
- An example of a lectin is **Concanavalin A**, which is derived from the jack bean (Canavalia ensiformis). This is a specific type of lectin that can be used in various biochemical applications.

5. **Conclusion**:
- Based on the information provided, the secondary metabolite that belongs to the group of lectins is **Concanavalin A**.

**Final Answer**: The secondary metabolite that belongs to the group of lectins is **Concanavalin A**.
