The brown adipose tissue of cold adapted hamsters has an approximately 35% higher phospholipid content than that of the controls. The basal turnover rate of phosphatidylinositol is higher in cold-adapted animals than in the controls, whereas 32P incorporation into phosphatidylcholine, phosphatidylethanolamine and diphosphatidylglycerol is not changed. Administration of norepinephrine increases the incorporation of 32P into both control and cold-adapted animals by 200% and 220% respectively. The 32P incorporation into other phospholipid fractions is not modified.
