Intro to Carbohydrates - Student developed note Use p. 29-33 to create your own intro notes to CARBOHYDRATES. Read all of the statement below before starting your note. These statements are formatted so you are able to effectively develop and organize your note. After your note is written answer the textbook question to further develop your understanding. Part A: INTRODUCTION Below are 5 introductory points about what a carbohydrate is and its uses from p. 29 To distinguish between monosaccharides you look for... PART B: LINEAR CHAINS vs. RING FORMATIONS OF CARBOHYDRATES Below are diagrams of the saccharides in LINEAR CHAIN FORM. Chains exist only when saccharides are NOT in solution (i.e. dry, crystal-like as you’d see them in a sugar bowl at home) Note the location of functional groups. a) triose sugar glyceraldhyde c) isomer of hexose sugar galactose b) isomers of a hexose sugar glucose d) isomer of hexose sugar fructose In solution, like when they are traveling in our blood, or mixed into food, linear chain carbohydrates tend to into their RING STRUCTURE Glucose has two important isomers in its ring state: a) alpha- Glucose 1-3 b) beta-glucose Note: to see the difference, see the location of the hydroxyl group on C 1 changes. An ogliosaccharide is a A glysolidic linkage is: PART C: Important types of olgliosaccharides and and polysaccharides Each molecule has a distinct glycosidic linkage that dictates its function. In the space below you will see examples of these molecules with their glycosidic linkages labeled and their functions/ uses outlined a) animal: disaccharides maltose sucrose b) animal energy storage: polysaccharides glycogen c) plant storage: Starch amylose (chain of alpha glucose) amylopectin (branched chains of alpha glucose) Now that you have your notes made and answer the questions p. 37 # 1-7 2-3 d) plant structure: Cellulose polymer of beta glucose e) insect structure: Chitin N-acetylglucosamine 3-3
