L-Ascorbic acid (AA), known as vitamin C, can form browning products by a non-enzymatic process during storage and the browning products cause deterioration of agricultural products. In the browning reaction, a red pigment, 2,2´-nitrilodi-2(2´)-deoxy-L-ascorbic acid ammonium salt (NDA), is generated from AA via L-scorbamic acid (SCA) as an intermediate. However, the biological activities of SCA and
L-抗坏血酸(AA),称为维生素C,在储存过程中会通过非酶过程形成褐变产品,褐变产品会导致农产品变质。在褐变反应中,AA经由L-松香酸(SCA)作为中间体从红色生成2,2′-nitrilodi-2(2′)-脱氧-L-抗坏血酸铵盐(NDA)。但是,SCA和NDA的生物活性尚未阐明。在这项研究中,我们使用ABTS自由基阳离子测定了SCA和NDA的抗氧化活性及其在PC12细胞中的神经突增生活性。SCA显示出比AA更强的自由基清除活性,而NDA几乎没有显示出任何活性。SCA和NDA以与AA相同的方式增强了二丁酰环AMP诱导的神经突生长。
