activity is much higher in rat liver than in quail liver, regardless of the nutritional state. The specific activity in the normal rat liver is 15times higher than that of the control quail group. The specific activity in rat liver after fasting increases by a factor of 2.3 over that of normal fed state | Rattus norvegicus |
| additional information | - |
activity is much lower in quail liver than in rat liver, regardless of the nutritional state. The specific activity in the normal rat liver is 15times higher than that of the control quail group. Activities in liver of the fastened, the 1% threonine-enriched and the 5% threonine-enriched group are about 2, 1.3 and 1.5times higher, respectively, than that of the control group of quails | Coturnix japonica |
