... ‘threshold peroxide tone’ is dependent on the fatty acid concentration present. At high substrate levels 15-LOX is blocked easier by glutathione/GPx. The 12-LOX is calciumindependent, however, requires an increased hydroperoxide tone for the activity (Vanderhoek et al., 1982; Walstra et al., 1987a). ...
