Lipids General characteristics 1. Little affinity for water because composed of carbon and hydrogen atoms, linked by non polar covalent bonds 2. Not made of regular, repeating subunits like other polymers 3. 4 groups that are all hydrophobic except phospholipids 1. Fats 1. Fats are made by what kind of reaction? 2. What is the difference between a saturated and unsaturated fatty acid? 3. What shape is each type of fatty? 2. Phospholipids 1. What are phospholipids composed of? 2. How do they differ from a triglyceride (fat)? 3. Phospholipids are amphipathic molecules. Which parts are hydrophilic / hydrophobic? What is amphipathic?
