We’re all Star Dust!

The smallest element, hydrogen, was formed in large amounts after the big explosion. Helium, lithium and beryllium also appeared. Higher amounts of energy were required to reveal heavier elements. Hydrogen and helium fused to form clouds, which collapsed to reveal the stars.

The temperature and pressure in the stars initiated nuclear fusion. Hydrogen atoms boiled together to reveal helium: As stars age, helium atoms form heavier elements such as carbon, nitrogen, and oxygen.

Depending on the mass of the star, this process sometimes continued and formed up to 26 elements (iron). After this critical point, the fusion reactions stopped emitting energy. The stars collapsed after consuming their usable fuels, then spraying gases and heavy elements into space.

Very large stars exploded to form supernovas. The energy produced in these explosions caused the formation of heavier elements than iron. The remains of these exploding stars combine with hydrogen to form new stars, and star and planetary systems such as our Solar System are born. The elements we see on Earth today have always emerged as a result of these events. So we can say that all the elements that make up our bodies come from ancient stars.

We’re all Star Dust!

Oxygen (65%)

Oxygen makes up more than half the weight of our body. It is one of the main components of water, one of the basic elements of biological molecules such as fat and protein.

Carbon (18.5%)

Carbon can form four bonds with other elements. It is therefore ideal for producing complex, large molecules. It is one of the basic building blocks of fat, protein, sugar and DNA.

Hydrogen (9.5%)

The third element in all biological molecules is hydrogen. There are more hydrogen atoms in our body than carbon and oxygen.

Nitrogen (3.2%)

Oxygen, carbon and hydrogen form the basis of all biological molecules, but most other elements are used in small proportions. Nitrogen is present in both DNA and proteins.

Calcium (1.5%)

Calcium is found in bones and teeth. Cells are one of the elements used in muscle and nerve functions while sending signals to each other.

Phosphorus (1%)

Like calcium, phosphorus is one of the elements that strengthen bones and teeth. It also plays a role in the use of energy, is one of the basic building blocks of DNA and serves to hold the entire DNA structure together.

Potassium (0.4%)

Potassium ions are found in cells and body fluids. They are used by nerve cells and muscle cells because they carry electrical charge.

Sulfur (0.3%)

Sulfur is one of the building blocks of protein. It can form strong bonds with other sulfur atoms and play a role in the formation of proteins.

Sodium (0.2%)

Sodium is also responsible for transporting the electric current inside the body. It plays a role in the realization of nerve and muscle functions together with potassium and chlorine.

Remaining (0.4%)

In addition to these, chlorine, magnesium, manganese, iron, fluorine, cobalt, copper, zinc, selenium, molbidenium, iodine, lithium and aluminum are also present in our body.
