Fig. 5. Lipid composition and fluidity of liver microsomes from four vertebrate
species. (A) Correlation between unsaturated fatty acid content and body
temperature. (B) 1,6-diphenyl-1,3,5-hexatriene (DPH) anisotropy at 21°C
for each species (mean±s.d., three separate preparations). Note that
the relationship between DPH anisotropy values for different species does not
change significantly when measurements are done over a temperature range
between 2 and 40°C (Logue et al.,
2000).
