毒理性
N-乙酰天冬氨酸的主要拟议功能包括:1)一种参与大脑中流体平衡的神经元渗透调节物;2)作为少突胶质细胞(负责神经元轴突髓鞘化的胶质细胞)中脂质和髓鞘合成的乙酸盐来源;3)合成重要的神经元二肽N-乙酰天冬氨酰谷氨酸的前体;4)N-乙酰天冬氨酸可能还参与神经元线粒体中从氨基酸谷氨酸产生能量的过程。血浆、脊髓液和尿液中积聚过量的N-乙酰-L-天冬氨酸已被发现具有毒性。另一方面,根据大脑的体内谱,N-乙酰-L-天冬氨酸浓度的降低与低乙酰天冬酸血症等疾病有关。
The primary proposed functions of N-acetylaspartic acid include: 1) A neuronal osmolyte that is involved in fluid balance in the brain; 2) a source of acetate for lipid and myelin synthesis in oligodendrocytes, the glial cells that myelinate neuronal axons; 3) a precursor for the synthesis of the important neuronal dipeptide N-acetylaspartylglutamate; 4) N-acetylaspartic acid may also be involved in energy production from the amino acid glutamate in neuronal mitochondria. Excess amounts of N-acetyl-L-aspartic acid accumulated in plasma, spinal fluid, and urine have been found to be toxic. On the other hand, decreased concentration of N-acetyl-L-aspartic acid according to the in vivo spectrum of the brain has been related to disorders such as hypoacetylaspartia.
