The effect of cold and fasting on the carnitine concentration in the brown adipose tissue of rats.
The ratio of aceytlcarnitine to carnitine was unchanged in the interscapular brown fatty tissue of rats which were kept at 5 degrees C. The quantity of total acid soluble carnitine relative to the fat-free dry weight was also unchanged. On the other hand a small decrease of the environmental temperature from 23 degrees C to 18 degree C and 20 degrees C resulted in a significant increase in the acetylcarnitine to carnitine ratio.
