Organic
Compounds
From yesterday: What is an organic
compound?
• Naturally occurring (animal or plantproduced or synthetic) substances
containing mainly carbon, hydrogen,
nitrogen, and oxygen.
• The compounds in living things are
carbohydrates, lipids, proteins, and
nucleic acids
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.
Oxygen
• Oxygen is necessary for respiration. You
will find this element in the lungs, since
about 20% of the air you breathe is
oxygen.
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.
Hydrogen
• Hydrogen is a component of the water
molecules in the body, as well as most
other compounds.
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.
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.
Sulfur
• Sulfur is a component of many amino
acids and proteins.
