一般說明
谷丙转氨酶（GPT）主要分布于肝脏。
研究领域：细胞信号传导
研究领域：细胞信号传导
應用
猪心谷丙转氨酶已用于：
- 检测其对人工合成的3-甲基-2-酮戊二酸外消旋混合物进行转氨反应的能力
- 去除人胚肾细胞(HEK293)培养基中的谷氨酸
- 研究乳酸脱氢酶(LD)-丙氨酸转氨酶(ALT)酶偶联反应系统的动力学
生化／生理作用
谷丙转氨酶（GPT）介导氨基从 l-丙氨酸转移到 α-酮戊二酸，从而产生丙酮酸和谷氨酸。因此，GPT 在糖异生和氨基酸代谢中发挥着关键作用。报道显示多种肿瘤中都有GPT参与。
谷丙转氨酶 (GPT) 存在于体内大多数细胞中，但在肝脏中浓度最高。由于在肝细胞坏死后 GPT 释放入血液，可作为肝脏疾病的标志物。
單位定義
一个单位在-37°C、pH 7.6且L-丙氨酸存在条件下将 1.0μmol 酮戊二酸转化成 L -谷氨酸。
