Eleidin occurs in

Options

A. Stratum germinativum
B. Stratum spinosum
C. Stratum granulosun
D. Stratum lucidum.

Answer

**Step-by-Step Solution:**

1. **Understanding Eleidin**: Eleidin is an intracellular protein that is specifically found in the skin. It plays a role in the process of keratinization.

2. **Identifying Skin Layers**: The skin consists of several layers, primarily the epidermis, which includes the stratum germinatum (basale), stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.

3. **Locating Stratum Lucidum**: Among the options provided (stratum germinatum, stratum spinosum, stratum granulosum, stratum lucidum), we need to identify where eleidin is located. The stratum lucidum is a clear, translucent layer of dead skin cells.

4. **Characteristics of Stratum Lucidum**: This layer is typically found in thicker areas of the skin, such as the palms of the hands and the soles of the feet. It is composed of dead keratinocytes that are rich in eleidin.

5. **Formation of Eleidin**: Eleidin is formed from the transformation of keratohyalin, an amino acid complex that contributes to the process of keratinization in the skin.

6. **Final Conclusion**: Based on the information, eleidin occurs in the stratum lucidum.

**Final Answer**: Eleidin occurs in the stratum lucidum.
