Leukotriene A4

Leukotrien A4

Svensk definition

(2S-(2 alfa,3 beta(1E,3E,5Z,8Z)))-3-(1,3,5,8-tetradekatetraenyl)oxiranbutansyra. En instabil allylepoxid som bildas av det omedelbara förstadiet 5-HPETE via stereospecifikt avlägsnande av en proton i position C-10 och dehydrering. Dess biologiska verkan bestäms främst av dess metaboliter, t ex leukotrien B4 och cysteinylleukotriener. Alternativt omvandlas leukotrien A4 till leukotrien C4 medelst glutation-S-transferas eller till 5,6-di-HETE genom epoxidhydrolas.

Engelsk definition

(2S-(2 alpha,3 beta(1E,3E,5Z,8Z)))-3-(1,3,5,8-Tetradecatetraenyl)oxiranebutanoic acid. An unstable allylic epoxide, formed from the immediate precursor 5-HPETE via the stereospecific removal of a proton at C-10 and dehydration. Its biological actions are determined primarily by its metabolites, i.e., LEUKOTRIENE B4 and cysteinyl-leukotrienes. Alternatively, leukotriene A4 is converted into LEUKOTRIENE C4 by glutathione-S-transferase or into 5,6-di-HETE by the epoxide-hydrolase.
