1. Organic Molecules

2. Organic Molecules Carbon = building block of life Carbon
4 outer electrons (8 needed)
Up to 4 bonds with other atoms
Monomer: Small carbon molecules
Ex: Amino acid
Polymer: chain of linked monomers
Ex: Protein

3. Carbon creates 4 bonds to be stable

4. Carbohydrates C: H: O = 1: 2: 1 Readily available food source
Monomer: Monosaccharides
Simple sugars
Bond to form larger molecules
Polymer: Di or polysaccharide
Complex sugar

5. Polymer: Polysaccharide
Long chain of monosaccharides (no fixed length)
Starch (pictured) : excess plant sugar converted & stored
Glycogen: animal starch stored in liver & muscles
Cellulose: used in plants to make cell walls
