This category featured a furan ring at C-14, 15, 16 positions and a ketonic group at C-1 or C-3 position.
In these conditions, the authors hypothesized an increase of the use of ketonic bodies as a source of energy in coeliac patients, consistently with the higher observed levels of 3-hydroxybutyric acid in blood and acetoacetate in urines [49].
