Keyword search and word combinations used to determine whether uncoupling proteins (UCP) use leaks to control oxygen species (ROS).

Uncoupling Proteins	Reactive Oxygen Species	Fuel Metabolism
UCP1 UCP2 UCP3 uncoupling protein 1 uncoupling protein 2 uncoupling protein 3	ROS Glutathionylation lipid hydroperoxide superoxide 4-hydroxy-2-nonenal hydroxynonenal	fatty acid oxidation fatty acid export fatty acid transport

(UCP1 OR UCP2 OR UCP3 OR “uncoupling protein 1” OR “uncoupling protein 2” OR “uncoupling protein 3” OR “uncoupling protein one” OR “uncoupling protein 2” OR “uncoupling protein 3”) AND (“reactive oxygen species” OR ROS OR glutathionylation OR “lipid hydroperoxide” OR superoxide OR 4-hydroxy-2-nonenal OR hydroxynonenal) AND (“oxidative stress” OR “fatty acid oxidation” OR “fatty acid export” OR “fatty acid transport”).
