Delta8-fatty-acid desaturase (EC 1.14.19.4 Delta8-sphingolipid desaturase EFD1 BoDES8 SLD Delta8 fatty acid desaturase Delta8-desaturase) is an enzyme with system name phytosphinganinehydrogen donor:oxygen Delta8-oxidoreductase. This enzyme catalyses the following chemical reaction phytosphinganine + reduced acceptor + O2 Delta8-phytosphingenine + acceptor + 2 H2OThis enzyme which has been found mainly in plants introduces a double bond at Delta8 of C18 and C20 fatty acids.
