Before revision:  We present a  framework for the construction and analysis of metabolic reaction networksthat can be tailored to reflect different environmental conditions . Using context-dependent flux distributions from Flux Balance Analysis (FBA), we produce directed networks with weighted links representing the amount of metabolite flowing from a source reaction to a target reaction per unit time. Such networks are analyzed with tools from network theory to reveal salient features of metabolite flows in each biological context.
