식물의 Ascorbic Acid의 기능과 대사경로

Functions and Metabolic Pathway of Ascorbic Acid in Plant

During the last few years, considerable progresses have been made in understanding of roles and biosynthesis of ascorbic acid (AsA) in plants. The concentrations of ascorbic acid is 2-4 mM in leaf cells, but much higher at the chloroplast. There are three forms of ascorbic acid in the plant mainly ascorbic acid (AsA), monodehydroascorbic acid (MDHA) and dehydroascorbic acid (DHA). AsA in plant cell performs antioxidants by changing those three forms. And AsA promotes cell division and elongation There was new pathway of ascorbic acid metabolism. It is called pathway of Smirnoff-Wheeler. This report will provide understanding of AsA in plants, and also provide
