1 Bell Ringer On what side of the equation would you see H20 for a dehydration synthesis reaction? I ate a big breakfast and now food is digesting in my stomach. Is this hydrolysis or dehydration synthesis? What does synthesis mean? Define polysaccharide.

2 Bell Ringer On what side of the equation would you see H20 for a dehydration synthesis reaction? I ate a big breakfast and now food is digesting in my stomach. Is this hydrolysis or dehydration synthesis? What does synthesis mean? Illustrate hydrolysis. Draw a polysaccharide.

3 Carbohydrate Lab

4 Organic Compounds: The Molecules of Life
Any compound containing carbon (also oxygen and hydrogen) Two exceptions: CO2 and CO Also called organic chemistry Four Macromolecules (large molecules): Carbohydrates Proteins Lipids Nucleic Acids

5 Carbon’s Bonding Behavior
Outer shell of C has 4 e-’s Can hold 8 e-’s Each C atom can form covalent bonds with up to 4 atoms C may form single, double, or triple bonds

6 (ball-and-stick model)
Bonding Arrangements Carbon atoms can form chains or rings Other atoms project from the carbon backbone Glucose (ball-and-stick model)

7 Carbohydrates Ratio is always 1 C: 2 H: 1 O or C1H2O1 Functions 
provide energy Structural support Energy comes from breaking the C-H bonds Subunit/Building Block is a monosaccharide Aka -- simple sugar

8 Monosaccharide Building block of carbohydrates AKA, simple sugar
Examples: Glucose Fructose Galactose Ribose Deoxyribose

9 Monosaccharide Examples
glucose

10 Disaccharide Two monosaccharides that have been linked together
What type of chemical reaction links them together? What type of chemical reaction breaks them apart during digestion? Examples Sucrose: glucose + fructose Lactose: glucose + galactose Maltose: glucose + glucose

11 Disaccharide Examples
Sucrose

12 Polysaccharides Many monosaccharides linked together (usually more than 8) Some provide energy Starch  plants Glycogen  animals (stored in liver & muscle) Some provide structural support Cellulose  plant cell walls Chitin  fungi cell walls & insect exoskeleton

13 Polysaccharides Examples
Glycogen

14 Carbohydrates: Examples
Monosaccharides Simple sugars Glucose, fructose, galactose Disaccharides Two simple sugars Sucrose, Maltose, and Lactose Polysaccharides Complex carbohydrates Glycogen & starch (storage) Chitin & cellulose (structural) Cellulose fibers in the plant cell wall.

15 How do carbohydrates impact your health?
