Organic Molecules

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

Carbon creates 4 bonds to be stable

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

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
