lipoxygenase product formation by colonic epithelium as measured by hydroxyeicosatetraenoic acid ( hete ) and leukotriene b4 ( ltb4 ) production ( 5-hete greater than 12-hete greater than 15-hete greater than ltb4 ) accounted for 58 % of the total colonic production of these moieties , whereas epithelium accounted for only 20 % of total colonic protein .
