title: The effect of cold and fasting on the carnitine concentration in the brown adipose tissue of rats.
abstract: 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.
