Industrial production of L-ascorbic Acid (vitamin C) and D-isoascorbic acid.
Pappenberger G, Hohmann HP. Pappenberger G, et al. Adv Biochem Eng Biotechnol. 2014;143:143-88. doi: 10.1007/10_2013_243. Adv Biochem Eng Biotechnol. 2014. PMID: 24258144 Review.
Similar concepts for industrial processes apply for the production of D-isoascorbic acid, the C5 epimer of L-ascorbic acid. D-isoascorbic acid has the same conformation at C5 as D-glucose and can be derived more directly than L-ascorbic acid from this …

The antiscorbutic action of L-ascorbic acid and D-isoascorbic acid (erythorbic acid) in the guinea pig.
Goldman HM, Gould BS, Munro HN. Goldman HM, et al. Am J Clin Nutr. 1981 Jan;34(1):24-33. doi: 10.1093/ajcn/34.1.24. Am J Clin Nutr. 1981. PMID: 7446456
The relatively weak activity of D-isoascorbic acid is probably due to poor transport to the tissues and ineffective binding to functional sites. This explains why the onset of scurvy is much more rapid after withdrawal of D-isoascorbic acid from the di …

Weak measurement-based sensor for the rapid identification of L(+)-ascorbic acid and D(-)-isoascorbic acid.
Zhong S, Guan T, Xu Y, Zhou C, Shi L, Guo C, Zhou X, Li Z, He Y, Ji Y. Zhong S, et al. Appl Opt. 2019 Nov 1;58(31):8583-8588. doi: 10.1364/AO.58.008583. Appl Opt. 2019. PMID: 31873343
The ability to identify L(+)-ascorbic acid from D(-)-isoascorbic acid in medicinal products is of practical interest. Based on the method of frequency domain weak measurement, a set of common optical path sensors for identification of L(+)-ascorbic acid and D(-)- …

Erythorbic Acid and Sodium Erythorbate.
Raj PS, Bergfeld WF, Belsito DV, Cohen DE, Klaassen CD, Liebler DC, Rettie AE, Ross D, Slaga TJ, Snyder PW, Tilton S, Fiume M, Heldreth B. Raj PS, et al. Int J Toxicol. 2023 Dec;42(3_suppl):37S-39S. doi: 10.1177/10915818231204257. Epub 2023 Sep 28. Int J Toxicol. 2023. PMID: 37767701
Effects of Different Bacteriostats on the Dynamic Germination of Clostridium perfringens Spores.
Liang D, Liu S, Li M, Zhu Y, Zhao L, Sun L, Ma Y, Zhao G. Liang D, et al. Foods. 2023 Apr 28;12(9):1834. doi: 10.3390/foods12091834. Foods. 2023. PMID: 37174372 Free PMC article.
The results showed that 0.07 ethylenediaminetetraacetate had a good inhibitory effect on C. perfringens spore growth, and the spore turbidity decreased by 4.8% after incubation for 60 min. Furthermore, 0.3 tea polyphenols, 0.8 D-isoascorbic acid, and 0.75 potassium …

Lohmann W, Pagel D, Penka V. Lohmann W, et al. Eur J Biochem. 1984 Feb 1;138(3):479-80. doi: 10.1111/j.1432-1033.1984.tb07941.x. Eur J Biochem. 1984. PMID: 6319135 Free article.
In the case of complete oxidation of ascorbic acid to dehydroascorbic acid, C(6)-OH is reestablished (indicating the reopening of the furanoid ring), while C(2)-OH as well as the C(2) = C(3) double bond have disappeared due to the deprotonation of C(2)-OH and C(3)-OH. In the case …
