Title: Organic Compounds
Date: 11/5/15
Did you know…
All living things are made up of just a few
elements.
Your digestive system uses specific elements
for energy to help your body survive (live).
Directions:
Copy the picture to the left onto
your foldable. Be sure to label
each colored section and write
the amount (percent of each
element).
So what are organic
compounds?
• Definition:
– Organic compounds are found in all living
things. Your digestive system breaks down
these special compounds to give your body
the energy and nutrients it needs to survive.
– All organic compounds have Carbon (C)
chemically joined with Hydrogen (H) and a
few other specific elements. BUT NOT all
carbon compounds are organic…
Organic compounds are made
out of these elements:
C – Carbon
H – Hydrogen
O – Oxygen
N – Nitrogen
P – Phosphorous
S - Sulfur
EXAMPLE
Glucose (sugar)
C6H12O6
(6 carbon atoms, 12 hydrogen atoms, 6
oxygen atoms chemically joined together)
Because carbon AND hydrogen are both
elements that make up organic compounds.
NOT an example:
Carbon Dioxide
CO2
(1 carbon atom, 2 oxygen atoms)
Because even though they are both elements
found in organic compounds the carbon is not
chemically combined with hydrogen.
HINT:
You can recognize an organic compound
because the chemical formula will have
carbon and hydrogen BOTH.
Carbon without hydrogen is NOT organic…

different elements for?

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.
• Stars are also made
Out of hydrogen.
YOU ARE made of
the SAME stuff as the
Stars in the sky!
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.
Homework
(only if you don’t finish this in class)
Get the worksheet from Ms. Red
You will identify each compound (chemical
formula) as either an organic compound or
as an inorganic compound based on the
elements that are chemically combined.
