 Obj: Relate the characteristics & functions of the 4 classes of macromolecules.  Do Now: What elements are the most important to living things?  HW: Macromolecule Coloring due Friday

Macromolecules Chapter 2 Section 3

What are the 6 elements most common to living things? 1. Carbon 2. Hydrogen 3. Oxygen 4. Nitrogen 5. Phosphorus 6. Sulfur Next to each write down the # of valence e’s & how many bonds each one can form.

Carbon Carbon forms the backbone of macromolecules Why? 4 valence electrons  4 bonds Forms long chains
