Application


  • The Vitamin C Enantiomers Possess a Comparable Potency in the Induction of Oxidative Stress in Cancer Cells but Differ in Their Toxicity.: The research compares the biochemical effects of Vitamin C enantiomers, including D-Isoascorbic acid, on oxidative stress in cancer cells, providing insights into their differential toxicity (Begimbetova et al., 2024).

  • Synthesis and potential antidiabetic and lipid-lowering activities of putative asperidine B and its desmethyl analogue.: This article discusses the synthesis of asperidine B analogues and their potential applications in biochemistry for antidiabetic and lipid-lowering activities (Thongpat et al., 2023).

  • Effects of Different Bacteriostats on the Dynamic Germination of Clostridium perfringens Spores.: The study investigates the impact of various bacteriostats, including D-Isoascorbic acid, on the germination dynamics of Clostridium perfringens spores, relevant to biochemical research in food safety (Liang et al., 2023).
