Biochemistry………………Monomers and Polymers

• What is biochemistry? The study of chemical process within living things

• KEY POINT #1: A atom is the smallest unit of matter. • The main atoms of life are:

»Carbon»Hydrogen»Nitrogen»Oxygen»Phosphorus»Sulfur

• KEY POINT #2: Many of the molecules in cells are so large that they are known as macromolecules.

MACROmolecule = Large moleculeMacromolecules are made from bonding of smaller

molecules. Macromolecules can also be called biomolecules or

organic molecules.

• KEY POINT #3: A macromolecule is a polymer that is formed when smaller units known as monomers join together.

• Monomer = 1 part• Polymer =many parts

KEY POINT #4: The monomers that combine to make a polymer may be identical or different.Monomers can be identical to each other such as

links on a metal watch. Monomers can be different like beads in a

multicolored necklace.

• KEY POINT #5: The 4 major groups of macromolecules found in living things are:

A. CarbohydratesB. ProteinsC. Nucleic AcidD. Lipids

Check Yourself1. How can you remember the six elements? Create a pneumonic device to help.

2. Which of the following is a macromolecule?

C6H12O6P2

C2H4F3O

Na2C4H2O2

3. Explain why the ones you circled above are considered macromolecules.

4. Here are two types of monomers. Using these as building blocks, create three different polymers. MONOMER #1: MONOMER #2:

Polymer #1

Polymer #2 Polymer #3

PARTNER CHECK: Explain why these are examples of a polymer.
