Part of the Nelson Biology Advanced Studies, this book covers biochemistry. It offers students an insight into the chemistry of life, and should be particularly helpful for those who are not taking chemistry at A-level. It has been written to cover both the core and options of A-level, AS-level and SCE Higher courses in biology, and relevant vocational courses in Further and Higher Education. Social, economic and environmental aspects are emphasized and enhanced by real-life case studies throughout. Questions aimed at increasing understanding and stimulating discussion are spread throughout the book with suggestions for investigations included. The books in the Biology Advanced Studies series provide a blend of accurate information and educational relevance by utilizing two authors on each book. In most cases, one is a practising teacher and examiner, and the other is a specialist from the industry.
