Figure 4.

Initial distribution in the storage and compartmentsX₁andX₂. Secreted insulin X(G,0)(dashed line) is the whole amount of insulin releasable by the pancreas at glucose concentration G. It is the integral over the initial packet distribution ξ(θ,0) (solid line). X₁is the releasable and X₂the non‐releasable amount of insulin. In the plot they can be identified as areas under the solid curve ξ(θ,0)ranging from θ = [0,Gand from θ = G∞), respectively. The figure is adapted from [4].
