3. Before we focus on organic
compounds…lets identify the concept
of inorganic
• Non living
• Never alive
• Does not contain carbon.
• Needed for life
• Autotrophs organize these into organic
compounds….
4. What are some important
INORGANIC compounds?
• H2O
• O2
• CO2
• Ca, Fe, P, Mg, K, Zn
(minerals)
• NO3 -
(nitrates)
8. Back to ORGANIC molecules
• Carbon Compounds
• Recall that Carbon forms 4 bonds
• Readily combines with other atoms
• Combines with itself as well.
• Produced by autotrophs and heterotrophs
c
12. Organic compounds form closed rings along with
the branches of the rings are called aromatic
compounds. The rings are formed with 6 carbon
atoms only. As the name suggests, they give off
very strong aroma. The number of variation of
ringed compounds is endless. Most of the
perfumes and pleasant odors from fruits and
flowers are due to such aromatic compounds.
15. All are Synthesized the same way… they are made of
smaller subunits..put together by dehydration synthesis
16. Dehydration synthesis- a
process where H2O is lost when
monomers combine to form long
chains called polymers

20. Questions
• Draw the molecular and structural formula for
carbon dioxide.
• Is this an organic molecule?
• How will this compound bond?
• What does dehydration synthesis mean?
• List 4 properties of carbon
• What is a buffer?
• What does polar mean? (do not refer to a
bear)
