Figure 2

An alternative way to view metabolic pathways. Metabolism involves many inter-connections between metabolites; however there are traditional ways to represent pathways. In this schematic 1, 2, 3 and 4 represent 4 individual pathways as they are traditionally considered, however a pathway exists in metabolism that can connect these 4 pathways via the intermediates of each. This pathway (highlighted in black) could biochemically be more important than 1, 2, 3 or 4.
