Abstract

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.

摘要

测定了犊牛肉用牛和反刍犊牛肝脏和脂肪组织中ATP柠檬酸裂解酶的活性以及血浆中葡萄糖和胰岛素的浓度。2. 犊牛肉用牛肝脏和脂肪组织中每克组织的ATP柠檬酸裂解酶活性显著更高。3. 尽管该酶每克组织的活性在肝脏中高于脂肪组织，但以每毫克蛋白质为基础进行比较时，脂肪组织中该酶的水平更高。4. 犊牛肉用牛的血浆葡萄糖和胰岛素水平也更高，这与ATP柠檬酸裂解酶活性以及先前研究的数据都非常吻合。
