Percentage composition of membrane fractions from cold- and warm-acclimated animals
| % Composition | ||||
|---|---|---|---|---|
| Animal | Membrane fraction | Cholesterol | Phospholipid | Protein |
| Warm-acclimated | PM | 9.5±0.4 | 23.1±1.1 | 67.4±0.8 |
| RDPM | 10.0±0.4 | 23.0±1.5 | 67.0±1.3 | |
| Raft | 16.1±1.0 | 27.6±1.5 | 56.3±1.2 | |
| Cold-acclimated | PM | 8.5±0.3 | 25.4±0.6 | 66.1±0.7 |
| RDPM | 7.3±0.2 | 27.5±1.0 | 65.2±1.1 | |
| Raft | 11.5±1.3 | 35.9±3.3 | 52.7±2.2 | |
Values are means ± S.E.M. (N=6) and are based on the assumption that cholesterol, phospholipid and protein content add up to 100% of the membrane.
PM, plasma membrane; RDPM, raft-depleted plasma membrane.
