Metabolic Flux Analysis

Definition

Metabolic flux analysis (MFA) is a quantitative method used to study the rates of metabolic reactions within a biological system. This technique helps in understanding how substrates are transformed into products and how cellular metabolism responds to changes in environmental or genetic conditions. MFA is crucial for metabolic engineering and biotechnology applications, as it provides insights into pathway efficiency and can inform strategies for optimizing bioprocesses.
