  1. Today’s Learning Target: You will be able to describe the structure and function of carbohydrates.

  2. Lets Carb Up!!! October 31, 2011

  3. A. Functions • Used by cells to store and releaseenergy • Simple Sugars = quick release energy • Monosaccharides and disaccharides • Starch = Longterm energy storage • Found in plants • Glycogen = Longterm energy storage • Found in animals • Stored in liver

  4. Functions (cont.) • Used to make cell structures • Cellulose • Structural component in plants • Chitin • Structural component in animals

  5. B. What are they made of? • Made of… (Hint: look at the name) • Carbon, Hydrogen, and Oxygen in a 1:2:1 ratio • General Formula (CH2O)n • n = number of carbons

  6. C. Types of Carbohydrates • Monosaccharides = monomer units • Means 1sugar or simple sugar • Ring Shaped molecules • Provide quick energy for cells

  7. Examples • Glucose • Most common • Plants make glucose during photosynthesis • Structure: ringshaped (see image) • Formula: C6H12O6

  8. Types of Carbohydrates (cont.) • Disaccharides • 2 monosaccharides linked together by Dehydrationsynthesis

  9. Macromolecule Formation Process = Dehydration Synthesis Removal of OH + H forms water, H2O Leaves bonding sites that join monomer units. Monomer Monomer OH H H2O Polymer

  10. Examples • Sucrose • Glucose and fructose • Found in regular table sugar • Lactose • Glucose and galactose • Found in dairy products

  11. Types of Carbohydrates (cont.) • Polysaccharides = Polymers • Can be made of 100 to 1000’s of monosaccharides • Many monosaccharides linked together by DehydrationSynthesis

  12. Examples • Starch – storage polysaccharide • Made entirely of glucose • Found in potato, rice, wheat • Other Examples • Glycogen • Cellulose • Chitin

  13. Let’s Do Some Practice Questions! Please grab your clickers!

  15. What elements are present in carbohydrates? (Answer all that apply) • C • H • N • O • P • S

  16. How does a simple sugar become a polysaccharide? • Adding water • Removing water • I need help with this.

  17. The molecular formula for Glucose is which of the following? • C6H12O6 • C12H22O11 • C6H10O5 • C12H12O6 • I need help with this.
