應用
Glutamic-Pyruvic Transaminase from porcine heart has been used to determine L-lactate levels in aqueous polyethylene glycol (PEG) solutions.
生化／生理作用
GPT is responsible for catalyzing the reversible transamination of α-ketoglutarate and alanine to glutamate and pyruvate. It also plays a critical role in the metabolism of amino acids and gluconeogenesis.
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。
