毒理性
L-丙氨酸是一种非必需氨基酸,在血浆中以自由状态大量存在。它通过转氨作用由丙酮酸产生。它参与糖和酸代谢,增强免疫力,并为肌肉组织、大脑和中央神经系统提供能量。支链氨基酸(BCAAs)被用作肌肉细胞的能量来源。在长时间运动期间,支链氨基酸从骨骼肌中释放,其碳骨架被用作燃料,而其氮部分用于形成另一种氨基酸,即丙氨酸。然后,丙氨酸被肝脏转化为葡萄糖。这种能量产生形式被称为丙氨酸-葡萄糖循环,它在维持人体血糖平衡方面起着重要作用。
L-Alanine is a non-essential amino acid that occurs in high levels in its free state in plasma. It is produced from pyruvate by transamination. It is involved in sugar and acid metabolism, increases immunity, and provides energy for muscle tissue, brain, and the central nervous system. BCAAs are used as a source of energy for muscle cells. During prolonged exercise, BCAAs are released from skeletal muscles and their carbon backbones are used as fuel, while their nitrogen portion is used to form another amino acid, Alanine. Alanine is then converted to Glucose by the liver. This form of energy production is called the Alanine-Glucose cycle, and it plays a major role in maintaining the body's blood sugar balance.
