There is no direct route of synthesis from sphinganine to sphingosine; it has to be acylated first to dihydroceramide, which is then dehydrogenated to ceramide.
Neexistuje přímá cesta syntézy od sfinganinu k sfingosinu; musí být nejprve acylován na dihydroceramid, který se pak dehydrogenuje na ceramid.
