Document Summary

3a) identify important monosaccharides, disaccharides and polysaccharides by structure. Student will be able to translate a fischer projection of a monosaccharide into a. For a 6 carbon sugar (5 ringed), the #2 carbon can flip. For a 7 carbon sugar (6 ringed), the #1 carbon can flip. Students will know the difference between a d and an l sugar and understand the biological significance of this difference. D = the second to last oh on the right side. L = the second to last oh in the left. Biologically significant: humans can"t process the l form due to enzymes. Cellobiose: glucose 1->4 glucose lactose : galactose 1->4 glucose lactose : galactose 1->4 glucose. Contains amylopectin, a(1-->4) glucose polymer with a(1-->6) branches, and amylose, a(1-->4) unbranched polymer. Animals amylopectin , but more mw with shorter and more frequent branches. Both starch and glycogen: alpha 1-4 linkages with alpha (1-6) branches. Wood so strong because cellulose (the layers of cellulose interconnected in.
