Book excerpt: Biochemistry Explained employs an innovative approach which has proven highly successful in the author's own classes. The author establishes a thorough understanding of the foundations of and common linkages between molecular structures and reactions, so that eventual interpretation of complex biochemical pathways and reactions is easy. All of the major molecular structures and biochemical pathways are explained, and, for the most part, these center on mammalian biochemistry. The text is supported by biochemical nomenclature and questions to bear in mind while reading. Higher learning sections are also provided for advanced students. Written in an informal, conversational style, this textbook will serve as an invaluable resource for any student who is struggling with the standard texts and for postgraduate students who need to refresh their knowledge.
