What is fluxome?
What is fluxome?
Fluxome. Similar to genome, transcriptome, proteome, and metabolome, the fluxome is defined as the complete set of metabolic fluxes in a cell. However, unlike the others the fluxome is a dynamic representation of the phenotype.
What are the two key assumptions of flux balance analysis FBA?
It achieves this by making two assumptions, steady state and optimality. The first assumption is that the modeled system has entered a steady state, where the metabolite concentrations no longer change, i.e. in each metabolite node the producing and consuming fluxes cancel each other out.
What are flux limiters in Fvm?
In general, the term flux limiter is used when the limiter acts on system fluxes, and slope limiter is used when the limiter acts on system states (like pressure, velocity etc.).
What is flux distribution?
These balances and bounds define the space of allowable flux distributions of a system—that is, the rates at which every metabolite is consumed or produced by each reaction.
How many metabolites are there?
The Human Metabolome Database The chemical data includes >40,000 metabolite structures with detailed descriptions, extensive chemical classifications, synthesis information and observed/calculated chemical properties.
What is flux biochemistry?
Metabolic flux is the passage of a metabolite through a given pathway over time. Examining the flow or flux of metabolites through pathways is a leading area of research in metabolism.
What is a flux analysis?
A flux analysis is a powerful tool that analyzes fluctuations in account balances over time. A flux analysis assists with forecasting, budgeting, and maintaining corporate integrity. Consistent analysis of change provides decision-driving insight, especially as flux data doesn’t just function as a predictive force.
What is flux balance analysis nature?
Flux balance analysis is a mathematical approach for analyzing the flow of metabolites through a metabolic network. This primer covers the theoretical basis of the approach, several practical examples and a software toolbox for performing the calculations.
What does flux mean in biology?
In general, flux in biology relates to movement of a substance between compartments. There are several cases where the concept of flux is important. The movement of molecules across a membrane: in this case, flux is defined by the rate of diffusion or transport of a substance across a permeable membrane.
