Transcript of The Role of Nitrogen in the Human Body

Nitrogen was discovered in 1772 in Scotland by Daniel Rutheford.
Did you know?
80% of the earth's atmosphere is made up of two nitrogen atoms that are bonded together, (N2)

Origin of Name
The name Nitrogen comes from the Greek words "nitron genes" .
Who and When?
Nitrogen gas (N2) makes up 78.1% of the earths air.
Nitrogen is found in all living systems as part of the makeup of biological compounds.
Boiling point: -195.8 °C
Melting point: -210 °C

Atomic number: 7
Atomic mass: 14.0067
Symbol : N

Source(s) of Element In Nature
The Role of Nitrogen in the Human Body
Atomic mass and Number
Biological compounds
Amides are another important nitrogen containing biological compound. An amine is a nitrogen atom bonded to a carbon atom.
An example of a biological compound formed with nitrogen is amides.
Balanced equations
Nitrogen and hydrogen, when balanced is ammonnia.
1/2 N2 + 3/2 H2 -----> NH3
Source of entry into the Body
The Role in The Body
What happens if the element is deficient/ excessive?
Optimal Amounts of The Element
Toxicity of The Element
Systems of the body that are affected by the element (Positively or negatively)
Is it available in vitamins? are they useful?
The air you breathe is around 78% nitrogen, so it would enter your body with every breath.
Just like us, plants and animals also need nitrogen to survive. Many plants can absorb enough nitrogen from compounds in the soil.
Nitrogen is found in many parts of our body, and it is essential for us to survive. About 3% of nitrogen is found in many of our organic molecules.
Nitrogen is found in the amino acids. These acids make proteins that we need in our body. Nitrogen also plays a role in the nucleic acids that make up our DNA.
In plants, if nitrogen is deficient it means the plant is unable to make enough chlorophyll. They may have symptoms such as poor plant growth, and their leaves may turn a pale green or yellow.
Determining the optimal amounts of nitrogen varies on the object.
For example, in soil it should contain an adequate supply of at least 40ppm of nitrogen. If there isn't enough, the soil may start to starve for more Nitrogen.
Toxicity of nitrogen may cause diseases such as Tuberculiosis.
In liquid form, nitrogen may cause extreme frostbite if it were to come in contact with your skin.
Nitrogen is a vital messenger for relaxing muscles in the body.
Some of the systems in the body that are affected by Nitrogen are :
- Cardiovascular system
- Immune system
- Central nervous system
- Peripheral nervous system
One of our resources for Nitrogen as a vitamin is L-carnitine liquid. This is a nitrogen-containing compound that is an essential role in making fatty acids available for muscle tissue.
