The science of proteomics involves the study of collections of proteins known as proteomes. This text for biologists, geneticists, and physiologists presents an introduction to mass spectrometry and its uses in the new field of proteomics. Liebler (pharmacy, U. of Arizona) begins with a discussion of the place of proteomics in the new biology, the nature of proteomes, and the tools of proteomics research. Applications covered include, for example, mining proteomes, protein expression profiling, and mapping protein modifications. Annotation c. Book News, Inc., Portland, OR (booknews.com)
