Labelling curves in a linear non-reversible pathway. Example of label propagation curves for a linear non-reversible pathway of five randomly sized metabolite pools, as proposed in the paper by Sokol and Portais [29]. Circles mark the position at which the first derivative of each labelling curve reaches maximum. In the original paper, this information has been used to analyse the label shock wave (LSW) propagation.
