free 4-hydroxysphinganine is produced in excised corn shoots by the direct hydroxylation of sphinganine and not from the breakdown of complex sphingolipids |

DL-threo-sphinganine is not an effective substrate. Individual ceramide species having 2-, 6-,8-, or 24-carbon fatty acyl chains amide-linked to sphinganine are hydroxylated with similar efficiency as free sphinganine |
