Eggs are a type of food that people have been eating for a long time in order to stay healthy and nourished. They are a crucial and valuable ingredient for cooking. The chemical composition of eggs is essential for many baking reactions.

Eggs are versatile and can be used in many different dishes, or even just by themselves. This makes them a good choice for any meal.

The egg is a protein-rich, oval-shaped food that is laid by female animals or birds of different species. Chicken eggs are the most commonly consumed eggs in the world.


Parts of An Egg

A chicken egg contains seven different parts that all serve a purpose in providing nutrients. These parts include the egg shell, the egg white (albumen), the yolk, membranes, air sac, the chalazas and the germinal disc. The different parts of an egg each serve a specific purpose.

The Eggshell

The eggshell is important because it contains every component of the egg. The presence of calcium carbonate gives the grain’s texture a shell-like quality.

The eggshell is a semi-permeable membrane that only lets moisture and air pass through.

In addition to providing a structure for the egg, the cuticle also serves as a natural defense against outside pathogens, like dust and bacteria. This protects the egg.

Albumen (Egg White)

The egg white is the part of the egg that surrounds and protects the yolk. The primary component of albumen is water, followed by proteins, vitamins, minerals, and other substances.

The albumen has three layers: an inner, middle, and outer layer. The strong layers of the eggshell contain a lot of proteins, which would help the chick develop if the egg were fertile.

Cooking the albumen in a non-fertile egg gives us the egg whites we eat.

Egg Yolk

The section of an egg in the middle is called the yolk. Its color can be light yellow to deep orange, depending on the breed of chicken that produced the egg.

The tiny yolk is responsible for housing most of the egg’s nutrients, including minerals, fats, vitamins, and proteins, as well as vitamins A, D, calcium, thiamine, riboflavin and phosphorus.


There are two membranes inside the eggshell, the outer membrane and the inner membrane. These membranes surround the albumen.

These incredibly transparent protein membranes contain some keratin. Egg membranes guard the inner components against bacterial invasion. The inner membrane is attached to the albumen and the outer membrane is attached to the eggshell.

Air Sac

This space is commonly referred to as the air sac. As an egg cools, the contents inside contract and form a space. Located at the larger end of the egg, the air sac is situated between the outer and inner membranes.

As the egg matures, air will enter the egg through the air sac, which replaces the moisture and carbon dioxide that has left the egg.


A chalazae is a twisted tissue string that lies at the opposite ends of the yolk and is a component of the egg white. There are egg white strings inside the egg that help to keep the yolk and germinal disc in place, so that the egg does not twist or become misaligned.

Eggs contain a high amount of vitamin D, which helps to increase bone density and strength, as well as improve the structure of the spine.

This food also contains significant amounts of calcium and phosphorous, which help strengthen bones and also enable key enzyme functions in the body. The consumption of eggs can help to prevent severe bone disorders such as arthritis, osteoporosis and rickets.

Helps Prevent Anemia

The high levels of iron in eggs help the body create healthy red blood cells and transport them throughout the body. Ample iron in the diet helps prevent iron-deficiency anemia, which causes decreased oxygen supply to vital organs.

Therefore, eating eggs every day will prevent anemia and its symptoms, such as dizziness and nausea.
