Which of the following is a derived lipid ?

Options

A. Steroid
B. Wax
C. Cutin
D. Suberin

Answer

To determine which of the following is a derived lipid, we need to analyze each option provided:

1. **Aroid**: This term typically refers to a family of plants (Araceae) and is not recognized as a type of lipid. Therefore, it cannot be classified as a derived lipid.

2. **Wax**: Waxes are long-chain fatty acids esterified to long-chain alcohols. While they are lipids, they are generally classified as simple lipids rather than derived lipids. Thus, wax is not the correct answer.

3. **Cutene**: Cutene is a type of waxy substance that forms a protective layer on plant surfaces, helping to prevent water loss. Like wax, it is not classified as a derived lipid.

4. **Subirin**: Subirin is a complex lipid that is found in the cell walls of plants and has protective functions. However, it is also not classified as a derived lipid.

Now, let's clarify what derived lipids are: Derived lipids are those that are derived from simple lipids through hydrolysis or other chemical processes. They include substances like steroids and terpenes.

Among the options provided, none of them are derived lipids. However, if we consider the context of the question and the explanation given in the video, it seems that the intended correct answer is **steroid**, which is a type of derived lipid.

**Final Answer**: The derived lipid from the options given is **steroid**.
