Carbohydrates,+Proteins+and+Lipids



- Styrofoam molecular modeling activity - 3D glucose
 * 9/2/10**

quiz over Elements and Water
- go over model building lab (formulas, etc.) - hydrolysis and condensation of sugars - go over types of mono- and disaccharides and poly- - be sure to refer to assessment statements

- bell quiz; name 3 mono-, 3 di- and 3 polysaccharides - opportunity for reassessment on Elements and Water quiz sometime soon - make up quiz tomorrow in office hours - condensation/ hydrolysis animations for carbohydrates - intro. carbohydrates in food lab; run controls iodine test Benedict's test
 * 9/7/10**

- CORRECTION: I referred to the iodine test for starch as the Biuret test, but this is incorrect. The solution for the test is sometimes referred to as Lugol's solution, named after... **Jean Guillaume Auguste Lugol** - hand back and go over Elements and Water quiz - review grading policy: grades can change on quizzes and test based on reassessment of relevant material (i.e. Elements and Water quiz assessment statements will be reassessed on next quiz/ test) - review assessment statements as what to refer to when studying - hand out list of Command Terms - lipids; small, naturally occurring hydrophobic or amphiphilic molecules (fats, waxes, oils)
 * 9/8/10**
 * functions (including energy storage)
 * condensation and hydrolysis
 * specifically triglycerides (fats) composed of glycerol and fatty acids

HW;

 * ===DBQ on page 50 of "Tiger" book===
 * ===review reading on lipids on pg. 50===

- carbohydrates in foods lab: "Design and run experiment to test for the presence of starch and reducing sugars (usually monosaccharides) in various foods."
 * 9/9/10**
 * include hypothesis with reasoning (hypothesis is __educated__ guess)
 * clearly outline method
 * display results appropriately (table, etc.)
 * write conclusion/ evaluation, connecting results to hypothesis and evaluating method

- hand out reprieve passes - discuss lab design, data collection and conclusion; especially controlling variables - hand out lab rubrics - period 8; go over lipids material
 * 9/10/10**
