1. An Option for Second-Semester Organic Chemistry at the University of Minnesota, Morris Tim Soderberg Organic Chemistry With a Biological Emphasis:

2. HHMI/AAMC SFFP Report Competency E4, part 6: Demonstrate knowledge of the chemistry of carbon-containing compounds relevant to their behavior in an aqueous environment. Examples: Recognize major types of functional groups and chemical reactions. Explain how molecular structure and geometry, including chirality, relate to chemical reactivity. Explain the chemical principles that allow structural inference about bio- organic molecules based on common spectroscopic analyses, such as NMR, UV/visible/IR absorption, or X-ray diffraction. Apply knowledge of the chemistry of covalent carbon compounds to explain biochemical reactions.

4. MR5 Committee Recommendations Chemical and Physical Foundations of Biological Systems (second of four test sections)... Understanding the mechanical, physical, and biochemical functions of human tissues, organs, and organ systems is important to the study of medicine. This section will test the extent to which examinees know the basic chemical and physical principles that underlie the mechanisms operating in the human body. It will further test examinees’ ability apply their understanding of these general principles to living systems.

6. The Preview Guide to MCAT 2015 Foundational Concept 5: The principles that govern chemical interactions and reactions form the basis for a broader understanding of the molecular dynamics of living systems. The content categories for this foundational concept include: 5A. Unique nature of water and its solutions 5B. Nature of molecules and intermolecular interactions 5C. Separation and purification methods 5D. Structure, function, and reactivity of biologically-relevant molecules 5E. Principles of chemical thermodynamics and kinetics

9. Organic textbooks place a heavy emphasis on lab synthesis – there is a need for a more biology-focused option. Current solution at UMM: First semester: Two sections, both covering same chapters of Bruice text Second semester: two options 1: ‘Standard’ o-chem course, continues with Bruice 2: Bio-flavored course, switches to ‘Organic Chemistry With a Biological Emphasis’. Cell Biology prerequisite

10. Open access textbook: online (Chemwiki at UC-Davis) pdf, print (lulu.com) Mechanistic organization, biological/medical examples take center stage Extensive references/links to primary literature NOT a Biochemistry text

11.

Other features of OCBE textbook/course Chapter on phosphates, phosphoryl transfer reactions Emphasis on importance of aldol/Claisen reactions in biological carbon-carbon bond formation and cleavage Eliminations: introduced later (chapter 14), focus on E1cb mechanism Sections on thiamine diphosphate and and pyridoxal phosphate coenzyme mechanisms Diversity of electrophilic reactions Redox: focus on nicotinamide- and flavin-dependent hydrogenation/dehydrogenation reactions Section on disulfide-dithiol redox chemistry, roles of glutathione and lipoamide

23. My hopes for final versions of the new MCAT and MCAT preview In lists of organic reactions, stress biological relevance, give examples Rethink references to purely synthetic chemistry (emphasize small set of synthetic ‘tools’, understanding of retrosynthetic strategy)
