Starter What are the differences between a dehydration and hydrolysis reaction? What are the properties that make water so important? What are the 4 major macromolecules? What are the two parts to a chemical reaction? Read 5.2 Concept Check 1 and 3
Starter How do you differentiate between a dehydration and hydrolysis reaction? Name the 4 major macromolecules.
Starter What do you need to know for each macromolecule? What are the names of the people you sit with? What are the common elements found in the macromolecules?
Starter How do animals store sugar? What does hydrophobic mean?
Starter What are enzymes and what do they do? What is the monomer of a protein? What holds two of those monomers together?
What are Macromolecules? Large Molecules formed by joining many subunits together. – Polymers Built by Dehydration Synthesis – Water Out Broken by Hydrolysis – Water In
Stored Sugar Organisms break sugars down – Use what they need – Store what they don’t Animals – Glycogen Plants – Starch
Lipids -- Function Hydrophobic Not a true polymer Function – Energy Storage – Cell Membrane Structure
Lipid Structure C, H, O General Fat structure 3 carbon backbone attached to three fatty acids – Saturated – all three fatty acids chains have maximum number of Hydrogen atoms Butter – Unsaturated – contain less than the maximum number of hydrogen atoms in one or more of its fatty acid chains fruits
