Most eggs sold in grocery stores are not fertilized, but a small white disc on the yolk's surface, known as the germinal disc, is one of several natural structures found inside an egg. This often-misunderstood anatomy is where a lesser-known, rope-like structure—the white membrane in an egg yolk—plays a critical role.

Egg yolk is a powerhouse of nutrients, containing high levels of lipids and proteins that are crucial for embryonic development. Within this complex matrix, a variety of biologically active components reside, including specific enzymes that play important roles in both avian biology and modern food production. Understanding which enzyme is present in egg yolk provides key insights into its functional properties.

An egg is a nutritional powerhouse, containing all the necessary nutrients to create new life. But where do eggs get their nutrients? This process is a fascinating journey determined by the laying hen's diet and intricate biological systems. The nutrients a hen consumes are strategically deposited into the yolk, egg white, and shell over a precise timeline during egg formation.
