Organic Molecules Polymers with Carbon

Polymers

Polymers and Monomers Dehydration synthesis: creating a polymer and water Hydrolysis: breaking down a polymer using water Animations

Carbohydrates: monosaccharides and disaccharides

Carbohydrates: Polysaccharides Starch

Carbohydrates Monomers: monosaccharides (simple sugars) Polymers: polysaccharides Starch (in plants) Glycogen (in animals) Fiber (cellulose in plants for cell walls) Function: Short term energy Cell wall structure

Proteins Monomer: Amino acids There are 20 different amino acids Polymers: All kinds of structural and functional proteins with special functions: enzymes,collagen, elastin, keratin, hemoglobin (polypeptides) Enzymes speed up chemical reactions Pictures of proteins

Lipids Monomers: glycerol, fatty acids Polymers: Functions: Fats Oils Waxes Functions: Long term energy storage Water-proofing Insulation Cell membrane structure Cushioning

Saturated v. Unsaturated Saturated Fats: no double bonds, straight structure, more likely to clog arteries Unsaturated fats: double bonds, bent structure, less likely to clog arteries

Lipids

Nucleic Acids Monomer: nucleotides Polymers: DNA and RNA Function: contain the code for proteins

Nucleotides
