Summary:

Chemistry pervades our life, giving shape and character to the world around us. It moulds our climate, fuels our transport, gives food its taste and smell. Most of all, chemistry powers life itself.Chemistry for the Biosciences leads students through the essential concepts that are central to understanding biological systems, using everyday examples and analogies to build their confidence in an often daunting subject. Placing an emphasis on clear, straightforward explanations, it fosters understanding as opposed to rote learning; by using relevant biological examples throughout, it illustrates
