The inner and outer membranes lying between the eggshell and the egg white contain keratin.
Keratin in Egg Membranes
These thin, transparent membranes are surprisingly strong due to their keratin content. Keratin is a protein also found in human hair, contributing to the membranes' protective function against bacterial invasion.
- Reference: Inner and Outer Membranes - Lying between the eggshell and egg white, these two transparent protein membranes provide efficient defense against bacterial invasion. If you give these layers a tug, you'll find they're surprisingly strong. They're made partly of keratin, a protein that's also in human hair.
While eggs are a good source of various nutrients like biotin, which is involved in keratin synthesis in the body, the egg itself doesn't contain significant keratin in the yolk or white. The keratin is primarily found in the structural membranes.
- Note: While eggs contain nutrients that support keratin production, this does not mean the egg itself is a significant source of the keratin protein.
