Description

General description

L-Ascorbic acid, an organic acid[1], is found abundantly in citrus fruits.[2] It is generally used as an antioxidant and pH adjuster in the cosmetic industry. L-AA is also used as a preservative and nutrient supplement in foods.[3]

Application

• Integrated metabolomics of big six Escherichia coli on pea sprouts to organic acid treatments.: Explores the antimicrobial effects of organic acids including L-Ascorbic acid on E. coli strains, offering insights into its use in food safety practices (Wang Y et al., 2022).


• Molecular Scalpel to Chemically Cleave Metal-Organic Frameworks for Induced Phase Transition.: Although not directly related to typical biochemical applications of L-Ascorbic acid, this innovative research uses it in material science to influence molecular structures, which could inform nanotechnology applications in biochemistry (Zhou X et al., 2021).
