BSCI170 Study Guide - Midterm Guide: Dehydration Reaction, Emergence, Amphiphile
Document Summary
Macromolecules = really big and complicated molecules which will sometimes do something useful for us. Cells use many large macromolecules that exhibit emergent properties based on their structure. Create macromolecules by stringing together monomer to create polymers. Dehydration removes a water molecule in effect, and it forms a new covalent bond. Definition: the chemical breakdown of a compound due to reaction with water. Nucleic acids = dna and rna in everything. Lipids can be large molecules, but not polymers. Glycerol + fatty acids = triacylglycerol (fat, triglyceride) No double bonds in fatty acid chains. 1 or more double bonds in fatty acid chains. Are related to fats, but have distinct chemical properties. Which is important because it can interact with water on one and not the other. A lot more polar at one end. Amphipathic molecules form micelles in water and help solubilize fats. Amphipathic phospholipids can form bilayers that are the basis for cell membranes.
