Unit 1, Chapter 4 Notes
AP Biology - Carbon & the Molecular Diversity
of Life (Preview Page)
Main Idea: Carbon is the backbone of all biological molecules–it
can form four covalent bonds, allowing it to make complex and
diverse organic compounds.
Concept 4.1
Organic chemistry is the study of carbon compounds.
Concept 4.2
Carbon atoms can form diverse molecules by bonding to four
other atoms.
Concept 4.3
A few chemical groups are key to molecular function.
This study guide covers Concept 4.1, Concept 4.2, and Concept
4.3, highlighting that organic chemistry is the study of
carbon-containing compounds, which are central to life because
carbon can form stable bonds with many elements. Carbon’s
ability to form four covalent bonds allows it to create a wide
variety of molecular structures, giving rise to the diversity of
organic molecules. Additionally, specific chemical groups play a
key role in determining a molecule’s chemical properties and
biological function. Together, carbon’s versatility and the
presence of functional groups explains the complexity and
functionality of the molecules essential for life.
