What is eggs made up of?

Yolk:

* Fat: About 30% of the yolk is fat, primarily in the form of cholesterol and triglycerides.

* Proteins: Yolk proteins make up around 16% of the yolk, including lecithin, which helps emulsify fat.

* Vitamins: Yolk is a rich source of fat-soluble vitamins like A, D, E, and K, as well as some B vitamins.

* Minerals: Yolk contains minerals like iron, phosphorus, and zinc.

* Water: Yolk also contains a significant amount of water.

White:

* Proteins: The white, also called the albumen, is primarily made up of proteins, including ovalbumin, conalbumin, and ovomucin. These proteins give the white its gel-like texture.

* Water: The white is about 88% water.

* Other components: The white also contains trace amounts of vitamins, minerals, and carbohydrates.

Shell:

* Calcium carbonate: The majority of the eggshell is made up of calcium carbonate, which provides its structural strength.

* Other minerals: The shell also contains small amounts of other minerals, such as magnesium and phosphorus.

Other:

* Chalazae: The chalazae are the twisted, rope-like strands that anchor the yolk in the center of the egg. They're made up of protein fibers.

* Air cell: The air cell is a small pocket of air at the blunt end of the egg. It forms as the egg cools after being laid.
