Metabolomics and Proteomics

Proteomics

Proteomics is the large-scale study of proteins .Proteins are vital parts of living organisms, with many functions. The proteome is the entire set of proteins that is produced or modified by an organism or system. Proteins are often used specifically to refer to protein purification and mass spectrometry. Proteomics has enabled the identification of ever increasing numbers of protein. Proteomics is an interdisciplinary domain that has benefitted greatly from the genetic information of various genome projects. proteomics is the study of biological systems. Proteins themselves are macromolecules, long chains of amino acids. This amino acid chain is constructed when the cellular machinery of the ribosome translates RNA transcripts from DNA in the cell's nucleus. The transfer of information within cells commonly follows this path, from DNA to RNA to protein.
