Objective: My aim is to introduce you to the concepts necessary for understanding how the biological world works at its most basic level, the chemical level. I realize that most of you have varied career plans, but if I can excite just one of you enough to want to apply chemistry in your career, I have succeeded in my objective. Format : This course will follow the text quite closely although the order of chapters may be rearranged. Lectures will be 50 min containing copious examples of real world applications of organic and biochemistry. Your active participation in the lecture is appreciated and encouraged, however, if time is a limitation, I may ask you to see me after lecture. It is vital that you read the material prior to coming to class. Do not bring your text to class. Why? Focus your attention on the lecture notes and the discussion going on in class. Don’t bother trying to flip through the text to see how my presentation differs. BE PREPARED TO TAKE YOUR OWN NOTES! I suggest a loose-leaf note book. Study Habits:

Read the material before coming to lecture, preferably the night before, not in the car on your way to lecture.
Recopy your notes after the lecture, preferably before the next lecture. When doing this, have the text open and expand you notes with points I may have glanced over or that you find of interest. Try to keep your notes in an outline format. Chemistry is a logical science, your notes should reflect that. Why recopy your notes? By recopying your notes you have actually written out the material 2 times. This is the best way I have found to learn material. In addition, you now have an excellent set of notes from which to study for exams.
Do Problems. Lots of them, preferably just after rewriting your notes. I suggest trying all of the problems yourself without looking at the answers. Then go back and convince yourself that you actually understand a particular problem. Do not be passive when doing problems. Seek human help before resorting to the answer key.
Study groups are fine but be cautious. Don’t rely on some one else to do the problems that you should be doing. Instead, I suggest that you talk about chemistry with your classmates and quiz each other with questions of your own origin.
By scheduling approx. 2 hr every night after lecture (that’s 6 hr/week) to do the above things, you will undoubtedly realize significant results. Attendance/Absences : This course will cover material quickly; it is very important that you attend class every period. No formal record of lecture attendance is maintained, however, you are responsible for information presented in class. It is your responsibility to get any missed material from another student. Attendance for exams is expected. Exams : Only the best three exam grades will be counted for your final score while your worst score will be dropped. Therefore, no makeup exams will be given. No exceptions. If you have a problem with a scheduled exam, see me by Friday September 3th. A special test may be scheduled to substitute for a missed exam due to death in the immediately family, however you must inform me of the absence prior to the exam. In the case of scheduled conflicts (i.e. university sanctioned events), you must make arrangements beforehand to take the exam prior to the event. Quizzes : There will be quizzes throughout the semester given. Your top four quiz grades will be counted toward your final quiz grade. There will be 5 quizzes given; therefore, no make-ups will be given for missed quizzes. Quizzes will be given in your laboratory section and will last 10 minutes. Homework : I will be assigning a few selected problems from the text book as we proceed though each chapter. I strongly suggest that you do them. In addition, I would strongly suggest you use the CD pack called GOB Chem Skill Builder that you probably purchased or used when you took CH104. This is an excellent resource and about 2 hr. a week spent doing these problems will serve you well on the exams. Extra Credit: Each exam including the final will have an extra credit question. Once you have logged on to WebCT and sent me a test email to let me know you are on the system, you will get 10 points. You must do this by Friday Sept. 5 to get the points. Lab: The purpose of the laboratory in CHEM 105 is to expose you to some of the basic techniques involved in organic and biochemical research as well as pharmaceutical and health related applications of chemistry. As seen in the grading scheme below, a major emphasis will be placed on your laboratory participation. Chemistry is a “hands on science”, and the labs are designed to expand what is presented in the lecture. See lab syllabus for more details.

CHEM 105 Life Chemistry II Laboratory Fall 2004 Lab Mon.(sect. A) 6-8PM (Dr. Iretski) and Tue.(sect. B) 2-4PM (Dr. Westrick) 308 Crawford Hall Dr. M. Werner office: CRW 314, phone: 635-2281 email: mwerner@lssu.edu Required Lab text : “ Brenstein/Hinckley: General, Organic, Biochemistry Experiments” Required Lab Extras : Lab Notebook with gridded carbon copy pages (available in the Book Store), safety goggles or glasses. The purpose of the laboratory in CHEM 105 is to acquaint you with laboratory techniques encountered in organic and biochemical research and to give you practical experience in performing these types of experiments. The experiments were selected based on the techniques used and to some extent application to lecture material. You will need to purchase a lab notebook with gridded duplicate pages. Goggles or safety glasses are

required and your must have them prior to the beginning of the lab. Both notebooks and safety

goggles are available at the book store.

Week of: Experiment Aug. 30 NO LAB Sept. 6 NO LAB Sept. 13 Check-in, Buffers Sept. 20 ☺ Acetic Acid in Vinegar Sept. 27 Molecular Models of Hydrocarbons Oct. 4 ☺ Synthesis of Esters Oct. 11 ☺ Synthesis of Aspirin Oct. 28 Quantative determination of glucose Oct. 25 Homemade Soap Nov. 1 ☺ Extraction of Caffeine from Coffee Nov. 8 Titration of Amino Acids Nov. 15 Photometric Determination of Invert Sugar Nov 22 No lab , Thanksgiving Nov. 29 ☺ Effect of Enzyme Concentration on Reaction Velocity Dec. 9 No Lab ☺ = Quiz in your lab section for that week. In order to complete the labs in the allotted time, you must be familiar with the lab procedure before the start of the lab period. Read the complete experiment and do the prelab questions (called Study Questions) before coming to lab. Prelab questions will be turned in at the beginning of each lab and graded as part of you lab grade. Keep in mind, in this laboratory, it is important that you understand what you are doing at each step and why you are doing it. If you are in doubt about what to do, ask, and remember that old lab axiom, “Never throw anything away.”

Lab attendance/absences: Attendance is mandatory, and remember, “Don’t be on time, be early!” For

grading purposes, the best 10 lab grades will be counted out of 11. Missed labs cannot be made up and will be recorded as a zero. Tardiness will result in loss of points (every 5 min late equals 2 pts) and you may miss important last minute instructions for the experiment. For most of the experiments, you will work with a partner; make sure it is a team effort. Labs turned in more than one week late will not be graded and will simply be returned. Lab Notebook: It is imperative that you maintain a complete notebook. This note book is to be separate from the lab manual. Anyone should be able to take your notebook and understand what was done, what results were obtained, and repeat the experiment. Write in the lab notebook with ballpoint pen, crossing through errors. Do not remove original pages from the notebook. I will collect the duplicate pages, except

for the results and discussion, at the end of lab. Results and discussion will be due the following week along with your analysis sheets from the lab manual. The lab notebook is to contain:

Your name, course name, and section number on the cover.
A table of contents on the first few pages
All your data, calculations, last minute modifications to the protocols, graphs, results, and conclusions must be in the notebook. Do not use scraps of paper to record any of these items.
Each page needs to show your name (and your partner's name), date, and experiment title.
Results should describe the results obtained (i.e. raw data and all calculations used to obtain "processed" data, tables and rough graphs). Final graphs, to be turned in, should be done on either a computer or with 10 mm x 10 mm graph paper.
Discussion should analyze and interpret results obtained. Safety: 1. Safety goggles or glasses must be worn at all times!!
Appropriate dress is required.
Report all injuries to me.
No smoking, eating, or drinking in the laboratory.
All chemicals, sharps, etc. must be disposed of properly. If you are not sure, ask.
Women who are pregnant need to discuss the course with me because of potential and known mutagenic and teratogenic chemicals involved in some experiments.
Come to lab prepared! Clean-up: At the end of the lab period, all reusable labware needs to be cleaned, rinsed with dH 2 O and allowed to dry. All equipment should be returned to their designated location. Water: We will be using lots of purified H 2 O this semester. If ever in doubt, use distilled water from the special taps located near the sinks at the back of the room. Assignments to be turned in: Lab assignments will consist of the following:
The prelab questions (called Study Questions) will be turned in at the beginning of that weeks lab.
The preprinted lab analysis sheets from the lab manual, as well as any assigned problems and the lab notebook pages will turned in at the beginning of the next lab period.
If you do not hand in assignments at the beginning of the lab, it is late and it will be assessed a late penalty. Laboratory Grading: Lab Performance (Subjective) 25 points Laboratory notebook 25 points Prelabs 50 points Analysis sheets 200 points Total 300 points

I retain the right to change this syllabus, as I deem necessary at any time during the semester. One final note: I have been in the lab long enough to know that things do not always go as planned when performing an experiment (i.e. you drop the test tube containing your precious sample, ect.). I will allow for unforeseeable error, however, if your errors are due to an obvious lack of preparation, leniency will not be forthcoming.
