ATP citrate lyase activity in liver and adipose tissue of veal or ruminating calves (Bos taurus).
1. The activity of ATP citrate lyase in liver and adipose tissue and the concentrations of glucose and insulin in plasma were determined in veal and in ruminating calves. 2. The activity of ATP citrate lyase per g of tissue was substantially higher in liver and adipose tissues of veal calves. 3. Although activity of this enzyme was higher in liver than in adipose tissue on a per g of tissue basis, comparison on a per mg protein basis showed the adipose tissue levels of the enzyme to be higher. 4. Both plasma glucose and insulin levels were also higher in veal calves which agreed well with both the ATP citrate lyase activity and with data from previous studies.
