									Chapter 2.3 - The Chemistry of Life

What do you think is the most important element in the world?

Why?




The Chemistry of Carbon

Characteristics

      Form strong                    bonds with other atom’s electrons

      Hydrogen, oxygen, phosphorus, sulfur, and nitrogen (mainly)

      Can form                     with itself.

Macromolecules

      Macro =

   

      made by a process known as                          .

      Polymerization

                            (smaller units) join together to form             .

Polymerization

      Monomers in a polymer may be                , or the monomers may be different.
