Hydroxyeicosatetraenoic acids (HETE), oxylipins, epoxides, docosanoids . . . Lipoxygenases are a family of enzymes that are characterized as non-heme iron proteins or dioxygenases, which catalyse the abstraction of hydrogen atoms from bis -allylic positions (1 Z,4 Z -pentadiene groups) of polyunsaturated fatty acids followed by stereospecific addition of dioxygen to generate hydroperoxides
5-Hydroxyeicosatetraenoic acid - Wikipedia 5-Hydroxyeicosatetraenoic acid (5-HETE, 5(S)-HETE, or 5S-HETE) is an eicosanoid, i e a metabolite of arachidonic acid It is produced by diverse cell types in humans and other animal species
The High Energy Transient Explorer (HETE-2) The High Energy Transient Explorer is a small scientific satellite designed to detect and localize gamma-ray bursts The coordinates of GRBs detected by HETE are distributed to interested ground-based observers within seconds of burst detection, thereby allowing detailed observations of the initial phases of GRBs
HETE 2 - Science@NASA NASA’s HETE 2 (High Energy Transient Explorer 2) detected and localized gamma-ray bursts (GRBs) Using a suite of instruments that simultaneously observed low-energy X-rays to gamma rays, HETE 2 computed the location of bursts on board and transmitted their coordinates as soon as they were calculated
HETE Quicklook HETE is a sun pointing, Momentum biased spacecraft with attitude controlled to + - 2 degrees by magnetic torque coils Actual spacecraft attitude can be determined to within + - 30 arcminutes with onboard sensors
The HETE-2 Satellite - NASA HETE-2, also known as the High Energy Transient Explorer was an international collaboration between USA, Japan, France, and Italy, headed by the Center for Space Research at MIT It was successully launched with a Pegasus launcher, on October 9 2000 from the Kwajalein missile range facility, an atoll in the Pacific ocean
20-Hydroxyeicosatetraenoic acid - Wikipedia 20-Hydroxyeicosatetraenoic acid, also known as 20-HETE or 20-hydroxy-5 Z,8 Z,11 Z,14 Z -eicosatetraenoic acid, is an eicosanoid metabolite of arachidonic acid that has a wide range of effects on the vascular system including the regulation of vascular tone, blood flow to specific organs, sodium and fluid transport in the kidney, and vascular pat
