| (A) During the uptake phase (0 to 6 hr) | |||
| Medium (nmoles/well) | Cells (nmoles/well) | Recovery 1 (%) | |
| α-TOH | 5.0 (drop) | 0.15 (increase) | 3% |
| γ-TOH | 3.0 (drop) | 0.86 (increase) | 29% |

| Cells (nmoles/well) | Medium (nmoles/well) | Recovery 2 (%) | |
| α-TOH | 0.054 (drop) | 0.042 (increase) | 78% |
