Metabolomics is the scientific study of chemical processes involving metabolites. Specifically, metabolomics is the "systematic study of the unique chemical fingerprints that specific cellular processes leave behind", the study of their small-molecule metabolite profiles. The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, which are the end products of cellular processes.[1]Thus, while mRNA gene expression data and proteomic analyses do not tell the whole story of what might be happening in a cell, metabolic profiling can give an instantaneous snapshot of the physiology of that cell.

In our project, we investigate the origin of formaldehydemetabolism using computer simulation ofbiochemical networks in tobacco. By utilizing the genetic engineering, threepathways of formaldehyde metabolism in tobacco were taken into account and three models of regulatory mechanism were established for these pathways. After that, we combined them by considering three pathways systematically and an integrated model was obtained.Below, let us describe the mathematical principles and all the procedures one by one.

Overview

Metabolomics is the scientific study of chemical processes involving metabolites. Specifically, metabolomics is the "systematic study of the unique chemical fingerprints that specific cellular processes leave behind", the study of their small-molecule metabolite profiles. The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, which are the end products of cellular processes.[1]Thus, while mRNA gene expression data and proteomic analyses do not tell the whole story of what might be happening in a cell, metabolic profiling can give an instantaneous snapshot of the physiology of that cell.

In our project, we investigate the origin of formaldehydemetabolism using computer simulation ofbiochemical networks in tobacco. By utilizing the genetic engineering, threepathways of formaldehyde metabolism in tobacco were taken into account and three models of regulatory mechanism were established for these pathways. After that, we combined them by considering three pathways systematically and an integrated model was obtained.Below, let us describe the mathematical principles and all the procedures one by one.
