Due to the lack of PGD2 production by keratinocyte and fibroblast cells, the anti-inflammatory cyclopentanones, PGJ2 and 15d-PGJ2, will not be produced during early experimental procedures either.

The estimated probability distribution for reaction 8 Kf. The value and weight of the literature values used to define the distribution are indicated by an orange dashed line. The x axis is plotted on a log-scale.
Dissociation Rate Constant (Kr)
This is a “Dependent parameter”, meaning that the log-normal distribution for this parameter was calculated using multivariate distributions (this is discussed in detail here). As a result, no confidence interval factor or literature values were cited for this parameter.
