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.

(Offered as CHEM 131 and BIOL 131.) What are the natural laws that describe how biological processes actually work? This course will use examples from biology such as human physiology or cellular signaling to illustrate the interplay between fundamental chemical principles and biological function. We will explore how bonding plays a central role in assembling simple biological building blocks such as sugars, amino acids, and fatty acids to form complex carbohydrates, proteins, and membranes. What underlying thermodynamic and kinetic principles guide systems to biological homeostasis or reactivity? What is pH, and how are proton gradients used to generate or change an organism's response? Emphasis is on using mathematics and physical sciences to understand biological functions. Three classroom hours and three hours of laboratory per week.
Enrollment is limited to 15 first-year students who are interested in science or premedical study, who are recommended to begin with either MATH 105 or MATH 111 (Intensive), and who are enrolled in a Mathematics course but not in CHEM 151. Admission with consent of the instructor. Fall semester. Visiting Lecturer Hebda.2016-17: 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 section is limited to 24 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 Burkett and Kushick. Spring semester: Professor Jaswal.2016-17: Offered in Fall 2016
A study of the basic concepts of chemistry for students particularly interested in natural science. Topics to be covered include atomic and molecular structure, spectroscopy, states of matter, and stoichiometry. These physical principles are applied to a variety of inorganic, organic, and biochemical systems. Both individual and bulk properties of atoms and molecules are considered with an emphasis on the conceptual foundations and the quantitative chemical relationships which form the basis of chemical science. This course is designed to utilize the background of those students with strong preparation in secondary school chemistry and to provide both breadth in subject matter and depth in coverage. Four hours of lecture and discussion and three hours of laboratory per week.
Limited to 40 students. Fall semester. Professor Marshall.2016-17: Offered in Fall 2016
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: Professors Leung.2016-17: Offered in Fall 2016
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 through laboratory experimentation 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 chemistry. Types of laboratory experiments to be discussed include expository, discovery, guided inquiry, and problem-based (open inquiry). Students will evaluate existing experiments and design original experiments and demonstrations for a variety of audiences, 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.

(Offered as BIOL 330 and CHEM 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.
Requisite: CHEM 161, PHYS 116/123, PHYS 117/124, BIOL 191 or evidence of equivalent coverage in pre-collegiate courses. Fall semester. Professors Carter and O'Hara.2016-17: Not offered
(Offered as CHEM 408 and BCBP 408.) This advanced seminar will focus on the ways in which chemical approaches have been used to study and engineer biological systems. We will explore a series of case studies in which the tools of chemistry have been brought to bear on biological questions and seek to answer the following: Did the application of small molecules that were designed and synthesized by chemists allow the researchers to elucidate biological phenomena that would have remained opaque using genetic and biochemical approaches? Do the findings suggest further experiments? If so, could follow-up experiments be carried out with known techniques, or would development of further chemical tools be required? Topics will include: the design and synthesis of chemical modulators of gene expression, signal transduction, and protein-protein interactions; chemical approaches to protein engineering and drug-target validation; activity-based proteomics; and chemical tagging of biomolecular targets. Readings will draw heavily from the primary scientific literature. Students will be expected to participate actively in class discussions, to write, and to present their work to the class. This course can be used to fulfill either the elective requirement for the CHEM major or the seminar requirement for the BCBP major. Two eighty-minute classes per week.

This course will focus on the fundamentals of medicinal chemistry, an organic-chemistry-based discipline that interfaces strongly with the biological and pharmaceutical sciences. Broadly, the field of medicinal chemistry is concerned with the discovery and preparation of biologically active compounds; the study of their metabolism; the interpretation of their mode of action at the molecular level; and the construction of structure-activity relationships. We will center our attention on the science of drug design, with an emphasis on the organic synthesis of viable drug candidates. The structure and function of macromolecular drug “targets” (e.g., receptors, enzymes, nucleic acids), as well as the mechanisms by which drugs interact with their targets, will also be considered. Furthermore, we will take into account the complexity of human physiology as we study the ways in which the physical and chemical properties of a drug candidate can influence its absorption, distribution, and metabolism in a human patient. Readings will be drawn from the primary scientific literature and case studies. Students will be expected to participate actively in class discussions, to write, and to present their work to the class.
