Biochemistry is the study of the chemistry of living things. This includes organic molecules and their chemical reactions. Most people consider biochemistry to be synonymous with molecular biology. The field of biochemistry is constantly changing with new discoveries being made all the time. Rapid advances in plant and animal biochemistry over recent years have fundamentally changed fields of science ranging from medicine to agriculture and food security. Biochemistry brings together a number of branches of science with a view to understanding the chemistry of life. Such a unique and privileged position at the interface of the traditional sciences makes a truly dynamic and exciting discipline. It provides basic insight into biological processes such as enzyme action, drug action, genetic engineering, photosynthesis and colour vision. The study of biochemistry demonstrates the complexity of the contents and reaction pathways in even the tiniest, most simple cell. There are many reaction cycles and involves complicated enzymes and other compounds which depend on many various factors to function correctly. It is here that we begin to see the amazing complexity of life. The book promises to fulfill the needs of the students, teachers and researchers in the field of botany, zoology, biotechnology, biochemistry as well as cell and molecular biology.
