CHEM191 - The Chemical Basis of Biology and Human Health
CHEM 191 is a 18-point paper available in the first semester and also at summer school.
NOTE: CHEM191 is also available at summer school only for students who have passed their internal assessment in the Semester One CHEM191 course but failed the paper overall. For more information on taking CHEM191 at summer school please check the summer school website.
It provides an introduction to concepts influencing chemical reactions in biological systems including
- Concepts of Chemical Bonding
- Thermodynamics/energetics of biological systems
- Properties of water
- Reaction rates and chemical equilibria
- Metals in biology - electron transfer, complexation
- Organic/carbon-based compounds - stereochemistry, reaction mechanisms, functional groups, polymers
- Biological molecules - carbohydrates, amino acids, nucleic acids, nucleic acids, proteins/enzymes
There are four lectures each week and one three-hour laboratory class every two weeks.
It is recommended that students enrolling in CHEM191 have a minimum of 14 credits in NCEA Level 3 Chemistry (or equivalent).

(Fortnightly in First-Year Chemistry Labs, Science I)
The terms requirement for CHEM191 is satisfactory attendance and performance in the laboratory course and terms test.
One three-hour written examination at the end of the semester (70%)
Laboratory exit tests (15%)
One one-hour terms test (15%)
Expectations at the completion of the course
• Apply an understanding of chemical structures and processes to biological systems
• Write chemical equations to describe reactions
• Use knowledge of chemical bonding and reaction mechanisms to predict and rationalise the outcome of chemical reactions
• Use mathematical procedures to analyse data and solve chemistry problems
• Safely use appropriate apparatus to carry out chemistry reactions in the laboratory
Interdisciplinary perspective, lifelong learning, communication

Students can purchase either the physical book, with access to MasteringChemistry (ISBN-13: 9781486042463)
An electronic version the text, readable on computers and tablets. Two versions of this are available:
- The first provides online 24 month access to the eText and MasteringChemistry (ISBN 9781442563896)
- The second allows for download of the eText (so you have it forever) and access to MasteringChemistry (ISBN 9781442559462 and 9781442563902)
Prices for these options are yet to be confirmed. Check with the University Bookshop email@example.com, 03 477 6976
Note that the textbook is Highly Recommended for CHEM191 and CHEM111, but not Essential. You are not required to have a copy of the book but it will be referred to in lectures.
