1 CODE: CHEM-236 TITLE: Biochemistry Institute: STEM DEPARTMENT: Chemistry COURSE DESCRIPTION: Upon completion of this course the student will be able to recognize and draw the structure and state the nature of the biochemicals important to life (carbohydrates, lipids and proteins), describe in detail the metabolic pathways that generate them and release energy from them. The student will also be able to describe and draw the structure of the gene molecules (RNA & DNA) and describe their metabolism and their role in protein synthesis. Basic concepts will be reinforced with appropriate laboratory experiences. PREREQUISITES: A grade of C or higher in CHEM-136, CHEM235, or CHEM 203. CREDITS: 5 LECTURE HOURS: 4 LAB/STUDIO HOURS: 3 REQUIRED MATERIALS: TEXT: TYMOCZKO, JL, BERG, JM, AND STRYER, L. (2011) BIOCHEMISTRY: A SHORT COURSE 2 ND EDITION NEW YORK: W.H. FREEMAN AND COMPANY. See the College Bookstore for textbook information. SAFETY GOGGLES: NEW JERSEY STATE LAW REQUIRES THAT ALL STUDENTS WEAR APPROPRIATE SPLASH AND IMPACT PROOF SAFETY GOGGLES WHILE PERFORMING LABORATORY EXPERIMENTS, OR DURING DEMONSTRATION OF EXPERIMENTS. THEY ARE AVAILABLE AT THE COLLEGE STORE. FULL-LENGTH LABORATORY COAT: ALL STUDENTS ARE REQUIRED TO WEAR A FULL-LENGTH LABORATORY COAT DURING THE LABORATORY PERIOD. COURSE LEARNING OUTCOMES: Utilize critical thinking skills to learn advanced concepts from biological chemistry ( Perform chemistry-based problem solving. Reinforcement of chemical concepts will be made as hands-on skills are developed in the laboratory program Read, interpret and present scientific papers and content Interpret spectra and other experimental results Draw and predict products of biochemical reactions Explain reaction mechanisms for enzymes and inhibitors Describe the energy and information flow in a biological system Isolate biochemical compounds through reactions GRADING STANDARD: Upon completion of the course, grades will be assigned as follows: A = % A- = 89-91% B+ = 86-88% B = 82-85% B- = 79-81%

2 C+ = 76-78% C = 70-75% D = 65-69% F = <65% Assessment results will be reported as the grade assigned by the faculty calculated to the first decimal place. These grades will be weighed according to course grading policy. In calculating the course grade, 0.5 will round up to the next numerical grade and 0.4 will round down to the next lower numerical grade. Lab: 1. The total laboratory grade will be based on laboratory experiments and laboratory quizzes given through the semester. The experiment average will make up 80% of the final grade and the quiz average will make up 20% of the final grade. 2. Any missed lab will be averaged in as a zero (0). 3. Any missed laboratory quiz will not be made up. 4. There may be a field trip to a research laboratory during one of the lab sessions. You will be expected to attend. Lecture: The lecture grade comprises 80% of the total grade. Assessments will be varied and could likely include exams, discussion sessions, lab reports, presentations, and a literature research project. DEPARTMENT POLICIES Chemistry Laboratory Policies 1. Students must attend their scheduled laboratory section. Students are not allowed to attend any other lab section for any reason. 2. Students must pass both the lecture and the laboratory portion of the course. 3. Students must wear googles, a full-length laboratory coat, and closed-toed shoes in the laboratory.
