where does do you find a high portion of elastin in chicken egg? what does this tell you about the mechanical properties of the shell membranes?

Elastin is a protein found in connective tissues that allows them to resume their shape after stretching or contracting. In a chicken egg, a high portion of elastin can be found in the inner and outer shell membranes.

The presence of elastin in the shell membranes of a chicken egg indicates that these membranes have elastic properties. This means that they can stretch and contract without breaking, which is crucial for the egg's ability to withstand various pressures without cracking. The elasticity provided by the elastin also allows the egg to expand as the embryo inside grows.

In summary, the high portion of elastin in the shell membranes of a chicken egg contributes to their mechanical strength and flexibility, protecting the egg and its contents.
