1. The content of carnitine, acylcarnitine and total acid soluble carnitine in brown adipose tissue of rats increases rapidly after birth, attaining a peak on about day 10 and then decreases. Similar changes with age were found for carnitine acetyltransferase activity in mitochondria from brown adipose tissue and heart. The activity of this enzyme in brain and in liver is much smaller, but also increases postnatally. 2. The activity of carnitine palmitoyltransferase in brown adipose tissue, however, decreases after birth then increases later in life. 3. Exposure of 18-day-old rats to the cold for 20 days leads to an increase in carnitine content in brown adipose tissue and raises the activity of carnitine acetyltransferase. The activity of carnitine palmitoyltransferase is not affected by cold adaptation.
