CHEM 301 - Unit 3 Review / CHEM301 - Unit 3 Review:LATEST 2021CHEM 301 - Unit 3 Review/CHEM 301 - Unit 3 Review. Unit 3 Learning Objectives 1. Differentiate between hydrophobic, hydrophilic, and amphipathic molecules. Hydrophobic molecules are NOT soluble in water. Hydrophilic molecules ARE soluble in water. Amphiphilic molecules contain both hydrophobic and hydrophilic residues. 2. Describe the structure of the following biological molecules: proteins, carbohydrates, lipids, and nucleic acids. Proteins – made up of AAs (20 common amino acids) Carbohydrates – simple sugar (6-carbon sugar) + contains an aldehyde or ketone functional group. Lipids – have polar functional group attached to one end of a hydrocarbon chain (composed of reduced hydrocarbons) Nucleic Acids – DNA and RNA  made up of deoxyribonucleotides and ribonucleotides  each has a sugar, a phosphate group, and a nitrogenous base
