"Now in its second edition, Biochemical Pathways continues to garner praise for its clear, full-color illustrations of the pathways and networks that determine biological function. This book examines the biochemistry of bacteria, plants, and animals. It offers a quick overview of the metabolic sequences in biochemical pathways, the chemistry and enzymology of conversions, the regulation of turnover, the expression of genes, the immunological interactions, and the metabolic background of health disorders. A standard set of conventions is used in all illustrations, enabling readers to easily gather information and compare the key elements of different biochemical pathways.” (publisher's description)
