CHEM191 The Chemical Basis of Biology and Human Health

Overview

An introduction to the concepts of chemistry underlying important processes in biology and human health, including chemical bonding, energetics, kinetics, equilibria and solubility, properties of water and solutions, acids, bases, complexation and electron transfer, mechanisms of organic reactions and properties of amino acids and carbohydrates.

CHEM 191 aims to instil a fundamental knowledge of chemical structure and reactivity, with particular focus on concepts that provide an understanding of why chemical reactions proceed and how this understanding may be applied to the chemical processes in biological systems.

CHEM 191 is a required part of the Health Sciences First Year programme at Otago and is a prerequisite paper for a number of other science courses.

CHEM 191 first semester: 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
   

CHEM 191 Summer School: This is a course designed to enable students who failed CHEM 191 in the first semester of the previous year to pass the paper and allow them to proceed to other courses that have CHEM 191 as a prerequisite.

Notes

(i) It is strongly recommended that students enrolling in CHEM191 have a minimum of 14 credits in NCEA Level 3 Chemistry (or equivalent). (ii) May only be taken at Summer School by students who were enrolled in CHEM191 in the first semester of the previous year, and passed the lab requirements but failed the paper as a whole.

Eligibility

First semester: There are no specific entrance requirements for students taking CHEM 191. However, having gained at least 14 credits at NCEA Level 3 (or equivalent) in chemistry is strongly recommended.

Summer School: This course can only be taken by students who were enrolled in CHEM 191 in the first semester of the previous year, but failed the paper with a minimum of 35%.

Teaching Arrangements

First semester:

• The course comprises 36 lectures and five 3-hour laboratories
• Attendance of laboratories is compulsory
• A progress test will be held

Summer School:

• The course comprises 36 lectures covering four modules
• There are several revision lectures
• There are eleven 1-hour tutorials (two per week)
• There will also be a 1-hour 15min progress test
• There is NO lab component to Summer School CHEM 191 as you carry over the marks that you were awarded for lab work in your previous year's CHEM 191 course

Textbooks

Chemistry: The Central Science - Brown, LeMay, Bursten, Murphy, Woodward, Langford, Sagatys & George 15th Edition

Students can purchase either the physical book
Or
An electronic version of the text.

Note that the textbook is highly recommended for CHEM 191 and CHEM 111, but not essential. You are not required to have a copy of the book, but it will be referred to in lectures.

Graduate Attributes Emphasised

Interdisciplinary perspective, Lifelong learning, Communication, Critical thinking.
