1. Elements in Organic Compounds

2. From yesterday: What is an organic compound?
Naturally occurring (animal or plant-produced or synthetic) substances containing mainly carbon, hydrogen, nitrogen, and oxygen.
The compounds in living things are carbohydrates, lipids, proteins, and nucleic acids

3. Elements of Life All living things are made up of just a few elements.
For example, all living things have a great deal of water. Oxygen and hydrogen make water. So they are important elements.
Other important elements include carbon and nitrogen.

4. 92% of the human body is composed of 3 elements:
carbon, hydrogen & oxygen

5. Oxygen
Oxygen is necessary for respiration. You will find this element in the lungs, since about 20% of the air you breathe is oxygen.

6. Carbon Carbon is found in every organic molecule in the body.
Carbon is ingested in food that is eaten and breathed in as a component of air. It is found in the lungs as a waste product of respiration, carbon dioxide.
All life is carbon-based.

7. Hydrogen
Hydrogen is a component of the water molecules in the body, as well as most other compounds.

8. Nitrogen
Nitrogen is a component of proteins, nucleic acids, and other organic compounds.
Nitrogen gas is found in the lungs, since most of the air you breathe consists of this element.

9. Phosphorus Phosphorus is found in the nucleus of every cell.
Phosphorus is part of nucleic acids, energy compounds, and phosphate buffers. The element is incorporated into the bones, combines with other elements including iron, potassium, sodium, magnesium and calcium.

10. Sulfur
Sulfur is a component of many amino acids and proteins.
