Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from each of two donors, and molecular oxygen is reduced or incorporated into a donor. Catalysis of the introduction of a trans double bond between C4 and C5 of the long chain base region of a sphingolipid. Sphingolipids are composed of a long chain base (LCB) amide-linked to a very long chain fatty acid.
