Living organisms require resources to fuel the processes necessary for staying alive. We require a certain number of calories to fuel metabolic processes and to provide building blocks to replace old cells and build new ones. Our food should provide a balance of proteins, carbohydrates, fats, vitamins and minerals that we need to consume regularly for a healthy existence. Yet humans have developed another relationship with food that can be either enriching or pathological. Sharing meals with others, developing the skills to enjoy the sensory pleasures of food, learning about other cultures through their gastronomic habits, and eating moderately while consciously are all examples of a deeper productive relationship with food. On the darker side, food can be a palliative to relieve our stress or satiate our addictions to sugar, fats, or salt. Modern humans can be so far removed from our food sources that we lose the connection between animal and meat and do not know if the food on our plates contains added hormones, pesticides, or genetically modified products. This course will examine our core requirements for food as we eat to live, and some of the cultural, social, historical, and culinary dimensions as we live to eat. Readings will include Barbara Kingsolver’s Animal, Vegetable, Miracle, Michael Pollan’s The Omnivore’s Dilemma, and selections from Modernist Cuisine: The Art and Science of Cooking by Nathan Myhrvold, Chris Young and Maxime Billet.
The two sections will meet together for 80-minute lecture/demos twice a week and each section will meet separately for a culinary lab every other week for two hours.
Limited to 30 students. Omitted 2016-17.2021-22: Not offered
This course examines the structure of matter from both a microscopic and macroscopic viewpoint. We begin with a detailed discussion of the physical structure of atoms, followed by an analysis of how the interactions between atoms lead to the formation of molecules. The relationship between the structures of molecular compounds and their properties is then described. Experiments in the laboratory provide experience in conducting quantitative chemical measurements and illustrate principles discussed in the lectures.
Although this course has no prerequisites, students with a limited background in secondary school science should confer with one of the CHEM 151 instructors before registration. Each laboratory and discussion section is limited to 20 students. In the fall, sufficient sections will be added to meet total enrollment. The spring semester is limited to two laboratory sections. Four class hours and three hours of laboratory per week.
Fall semester: Professors Leung and Marshall. Spring semester: Professor Burkett.2021-22: Not offered

The concepts of thermodynamic equilibrium and kinetic stability are studied. Beginning with the laws of thermodynamics, we will develop a quantitative understanding of the factors which determine the extent to which chemical reactions can occur before reaching equilibrium. Chemical kinetics is the study of the factors, such as temperature, concentrations, and catalysts, which determine the speeds at which chemical reactions occur. Appropriate laboratory experiments supplement the lecture material. Each laboratory section is limited to 24 students. In the spring, sufficient sections will be added to meet total enrollment. The fall semester is limited to two laboratory sections. Four class hours and three hours of laboratory work per week.
Requisite: CHEM 151 or 155 (this requirement may be waived for exceptionally well-prepared students; consent of the instructor is required); and MATH 111 or placement by the Mathematics department into MATH 121 or higher. Fall semester: Professor Young. Spring semester: Visiting Professor Bengali.2021-22: Not offered
There is a tremendous gap between the length scale of the molecular world and the macroscopic dimensions of our experience, but macroscopic observation and physical manipulations nonetheless lie at the heart of the experiments that gave rise to atomic theory and modern chemistry. Although sophisticated instrumentation has been developed to “image” atoms and molecules, macroscopic observation in the laboratory remains an essential component of teaching and learning chemistry at the elementary school, secondary school, and undergraduate level. This course focuses on the question of what makes an experiment effective as a tool for understanding and representing an unseeable world. Types of experiments to be discussed include expository, discovery, guided inquiry, and problem-based (open inquiry). Students will evaluate existing experiments and design experiments and demonstrations for a variety of audiences and learning needs, from elementary school students through undergraduates, with emphases on conceptual content, pedagogical style, and safety and environmental considerations. Two 80-minute discussion-based classes and one 3-hour lab per week.
Recommended requisite: CHEM 151 or CHEM 155; students with no college-level chemistry courses should consult with the instructor. Limited to 12 students. Omitted 2016-17.

(Offered as CHEM 330 and BIOL 330.) What are the molecular underpinnings of processes central to life? We will explore the chemical and structural properties of biological molecules and learn the logic used by the cell to build complex structures from a few basic raw materials. Some of these complex structures have evolved to catalyze chemical reactions with enormous degree of selectivity and specificity, and we seek to discover these enzymatic strategies. We will consider the detailed balance sheet that shows how living things harvest energy from their environment to fuel metabolic processes and to reproduce and grow. Examples of the exquisite control that permits a cell to be responsive and adapt its responses based on input from the environment will be considered. We will also consider some of the means by which cells respond to change and to stress. A student may not receive credit for both CHEM 330 and BCBP/BIOL/CHEM 331.

(Offered as PHYS 400, BIOL 400, BCBP 400, and CHEM 400.) How do the physical laws that dominate our lives change at the small length and energy scales of individual molecules? What design principles break down at the sub-cellular level and what new chemistry and physics becomes important? We will answer these questions by looking at bio-molecules, cellular substructures, and control mechanisms that work effectively in the microscopic world. How can we understand both the static and dynamic shape of proteins using the laws of thermodynamics and kinetics? How has the basic understanding of the smallest molecular motor in the world, ATP synthase, changed our understanding of friction and torque? We will explore new technologies, such as atomic force and single molecule microscopy that have allowed research into these areas. This course will address topics in each of the three major divisions of Biophysics: bio-molecular structure, biophysical techniques, and biological mechanisms.

This course will focus on topics in modern organic chemistry with an emphasis on structure, reactivity, and synthesis. We will expand on many of the concepts from introductory organic chemistry to develop a fundamental base of knowledge about organic reactions in the context of modern organic synthesis. Broadly, synthesis is the application of one or more reactions to the preparation of a target compound. The selection of reactions for a synthesis requires an understanding of structure, reactivity, and mechanism. We will center our attention on reactions that have found utility in organic synthesis and consider their mechanism, regio- and stereochemical characteristics, and reaction conditions. These reactions will be discussed in the context of complex molecule synthesis and issues of functional group compatibility, steric sensitivity, and stereoselectivity will be considered. Furthermore, the challenges of designing a multistep synthesis will be discussed and illustrated with classic examples from the scientific literature. Readings will be drawn from the primary scientific literature. Students will be expected to participate actively in class discussions and to present their work to the class.
