说明

應用

• Vanillin formation from ferulic acid in Vanilla planifolia is catalysed by a single enzyme: This study identifies that a single hydratase/lyase is responsible for converting ferulic acid to vanillin in Vanilla planifolia, providing insights into the natural vanilla flavor production process (NJ Gallage et al., 2014).


• Overview of the role of vanillin in neurodegenerative diseases and neuropathophysiological conditions: This review covers the role of vanillin in various neurodegenerative conditions, focusing on its pharmacological properties and applications in this field (C Iannuzzi et al., 2023).
