Learning Outcomes 31-46 Lecture 2, January 6, 2012 1. Be able to determine which types of covalent bonds are polar or non-polar based on a table of electronegativity. Nonpolar-below 0.5 Polar covalent-.7-1 Ionic- above 2 2. Illustrate the hydrogen bonding between water and polar covalent bonds. In notebook. Methyl, hydroxyl, carboxyl, amino, phosphate, carbonyl, sulfhydryl 3. Be able to draw the functional groups shown in Table 2.2, indicate which are capable of participating in hydrogen bonds. For those groups, illustrate how each hydrogen bonds with water. Methyl cant H-bond with water. One group not pictured here, but very important is a secondary amine: 4. For the following, illustrate how each pair forms H bonds:

Be able to define pK and illustrate the structure of a carboxyl group and an amino group above and below their respective pKs. Pk-pH where half groups are ionized and half where their not 7. Illustrate the different linkages found in polysaccharides and explain why cellulose is not considered a nutritional polysaccharide. Glycogen- α(1,4), α(1,6) highly branched Starch- unbrached, helical α(1,4) Cellulose- long, unbrached, β(1,4), body doesn't have enzyme to digest cellulose, undigestable.
