Metabolic networks are complex systems of interconnected biochemical reactions that occur within living organisms. These networks involve various molecules, such as enzymes, substrates, and products, which work together to facilitate processes like energy production, nutrient synthesis, and waste elimination. Understanding these networks helps scientists study how cells function and respond to changes in their environment. Researchers often use computational models to analyze metabolic networks, allowing them to predict how alterations in one part of the network can affect overall cellular function. This approach is essential in fields like systems biology and bioengineering, where insights from metabolic networks can lead to advancements in medicine, agriculture, and biotechnology.
