Chem 8B, Handout for Feb 4, 2009 Organic Oxidation and Reduction reactions (pp 269-270, 329), and Imines (pp 331-332) Oxidation = add oxygen by converting C-H bond into a C-O bond (increase # of C-O bonds) Reduction = add hydrogen by converting C-O bond into a C-H bond (reduce # of C-O bonds) Reducing agents add H 2 , or a hydride (H: ) to increase the number of C-H bonds. Examples of chemical reducing agents used with carbonyls are NaBH 4 and LiAlH 4 . (see page 329). There are also enzymes that can add H 2 to reduce a carbonyl. Examples of chemical oxidizing agents include O 2 , chromium reagents (such as CrO 3 , H 2 CrO 4 , and Na 2 Cr 2 O 7 ), and AgNO 3 . Notice a trend? They all have lots of oxygen atoms in the reagents. In addition to chemical reagents, enzymes can also perform oxidation reactions. Metabolic oxidation reactions are some of the most important reactions that occur in biological systems. We have already examples of biological oxidations with the enzyme cytochrome p450 (pages 280-281), but there are other enzymes that can also oxidize compounds. For example, alcohol dehydrogenase is an important enzyme that can

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
