Inorganic versus Organic by Mind Map: Inorganic versus Organic

1. Organic Compounds

1.1. Macromolecules

1.1.1. Carbohydrates Contain C, O, and H 2 H for every 1 O Three classes Monosaccharides Disaccharides Polysaccharides

1.1.2. Lipids Contains H, O, less C Sometimes P Main types Tryglycerides Steroids Eicosanoids Hydrophobic Insoluble in water

1.1.3. Proteins

1.1.4. Nucleic Acids

1.2. Contains carbon

1.2.1. Electroneutral Shares electrons Forms 4 covalent bonds Unique to living systems

2. Inorganic Compounds

2.1. Components

2.1.1. ACIDS Electrolyte Dissociate in water Releases hydrogen ions H+ Lower pH

2.1.2. SALTS Ionic compounds No H+ or OH- Electrolyte Ability to conduct electrical currents in solution Necessary for homeostasis

2.1.3. WATER Most abundant 60-80% of living cells High heat capacity Able to absorb and release heat with little temperature change Prevents sudden change in temperature High heat of vaporization Evaporation needs lots of heat Cools body down = homeostasis Polar solvent properties Dissolves and dissociates ionic substances (NaCl) Forms hydration layers around charged molecules Transportation Reactivity Hydrolysis: adding water to break down bonds Dehydration: removing water to create bonds Cushioning Protects organs from physical trauma

2.1.4. BASES Proton acceptor Take hydrogen ions H+ Higher pH

2.2. Do not contain carbon

2.3. CO2 and CO exceptions
