Proteomics is the large-scale study of proteins. Proteins are vital parts of living organisms, with many functions. The term proteomics was coined in 1997 in analogy with genomics, the study of the genome. The proteome is the entire set of proteins, produced or modified by an organism or system. This varies with time and distinct requirements, or stresses, that a cell or organism undergoes. Proteomics is an interdisciplinary domain that has benefited greatly from the genetic information of the Human Genome Project; it is also emerging scientific research and exploration of proteomes from the overall level of intracellular protein composition, structure, and its own unique activity patterns. It is an important component of functional genomics.

In the present book, fourteen typical literatures about proteomics published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on medical science, bioinformatics, genomics, proteins, ect. We hope this book can demonstrate advances in proteomics as well as give references to the researchers, students and other related people.
