What is main protein in egg yolk?

The main protein in egg yolk is phosvitin. It makes up about 10-15% of the total yolk protein.

Here's why it's important:

* Iron Binding: Phosvitin has a high affinity for iron, making it crucial for iron transport and storage in the developing chick.

* Emulsifier: It acts as an emulsifier, helping to stabilize the yolk's structure and prevent separation.

* Flavor and Texture: Contributes to the yolk's creamy texture and rich flavor.

While phosvitin is the most abundant, other important proteins in egg yolk include:

* Lipovitellin: A major storage protein for lipids and phospholipids.

* Livetin: A protein involved in lipid metabolism.

* Ovalbumin: Interestingly, ovalbumin is actually the main protein in egg white, but small amounts can be found in the yolk.

So, although egg yolk contains a complex mix of proteins, phosvitin reigns supreme in terms of quantity and significance.
