What is Life Made of?
Physical and Chemical sciences alone may not completely explain the
nature of life, but they at least provide the essential framework for
such an explanation.

Organic Chemistry
What makes Carbon Special? Why is Carbon so different from all the
other elements on the periodic table?
The answer derives from the ability of Carbon atoms to bond together
to form long chains and rings.
Organic Chemistry
Hydrogen bond
• Chirality
Polymerization
• Polymerization (definition):
• Forming of large organic macromolecules by the joining of smaller repeating
units called monomers
Bonding: Polymerization: Dehydration Synthesis
Dehydration Synthesis
• Dehydration Synthesis is the removal of a water molecule to form a
new bond.
