| Popis: | The influence of increasing dietary protein level, at the expense carbohydrate, on alanine aminotransferase (AAT) activity in liver and kidney of growing chicks was investigated.Approximately 85% to 90% of AAT activity in kidney was associated with the particulate fraction and only 10% to 15% with the soluble fraction. In liver, approximately 65% to 80% of AAT activity was associated with the particulate fraction and 20% to 35% with the soluble fraction.Increasing dietary protein, at the expense of carbohydrate, resulted in a linear increase in AAT activity in the particulate fraction of liver and kidney, although the magnitude of change in kidney was greater than that observed in liver. AAT activity in the soluble fraction of kidney was significantly increased when the dietary protein level increased. On the other hand, AAT activity in the soluble fraction of liver tended to increase, although insignificantly, when the percentage of energy from dietary protein increased from 10% to 40%. However, chicks fed diet containing 60% energy from protein had significantly higher AAT activity in the soluble fraction of liver than those fed diets containing from 10% to 40% energy from protein.Activity of phosphoenolpyruvate carboxykinase in the particulate fraction of liver and kidney was not affected by the dietary protein level. |
