| Ceramide | 461 ± 29 | 416 ± 24 | 451 ± 37 | 475 ± 25 |
| Glucosylceramide | 56.7 ± 9.2 | 53.4 ± 5.7 | 47.4 ± 5.2 | 46.1 ± 5.0 |
| Gangliosides | ||||
| GM3 | 22.5 ± 3.2 | 21.3 ± 2.9 | 17.3 ± 2.7 | 20.0 ± 2.2 |
| GM2 | 6.2 ± 1.0 | 5.9 ± 0.9 | 4.8 ± 0.8 | 5.0 ± 0.4 |
| GM1 | 11.6 ± 2.9 | 11.4 ± 2.2 | 5.6 ± 1.1 | 9.1 ± 1.5 |

Data are means ± SD. Animals were fed for 10 weeks with 0, 5, or 25 mg AMP-DNM/kg. Liver was collected and analyzed on ceramide, glucosylceramide, and ganglioside content.
