vitamin c

L-Ascorbic acid (Vitamin C) is a natural product that is a potent reducing agent and antioxidant. L-Ascorbic acid functions in fighting bacterial infections, in detoxifying reactions, and in the formation of collagen. L-Ascorbic acid is used in the treatment of scurvy.

L-Ascorbic acid sodium salt (Vitamin C sodium salt) is a more bioavailable form of vitamin C that is an alternative to taking ascorbic acid as a supplement.

3-O-Ethyl-L-ascorbic acid is a cosmetic tyrosinase inhibitor with whitening ability and is a stabilized vitamin C derivative. It also has antioxidant properties.

1,4-D-Gulonolactone (D-Gulonic acid γ-lactone) (also known as reduced ascorbic acid, RAA) is the substrate of the enzyme L-gulono-1,4-lactone oxidoreductase (EC 1.1.3.8), which catalyzes the last step of the biosynthesis of L-ascorbic acid (vitamin C) in plants and animals. The enzyme L-Gulono-1,4-lactone oxidase is missing in scurvy-prone, vitamin C-deficient animals, such as humans. 1,4-D-Gulonolactone is present in human blood and has been used as one of the markers to compare changes in exercise-induced oxidative stress.

Cyclic AMP (cAMP) (Adenosine 3',5'-cyclophosphate) combined with vitamin C treatment of children with viral myocarditis has exact curative effect, and it can improve cardiac function of patients and improve immune function.

L-Ascorbic acid 2-phosphate trisodium (Sodium ascorbyl phosphate) is utilized in biocatalytic dephosphorylation for electric power generation and electrochemical detection assays.

Vitamin K2 (Menatetrenone) is a menaquinone compound and form of vitamin K2 with potential antineoplastic activity. Menatetrenone may act by modulating the signaling of certain tyrosine kinases, thereby affecting several transcription factors including c-myc and c-fos. This agent inhibits tumor cell growth by inducing apoptosis and cell cycle arrest.

L-Gulono-1,4-lactone, a substrate of L-gulono-1,4-lactone oxidoreductase, catalyzes the final step in the biosynthesis of L-ascorbic (Vitamin) C.

Anisindione is a synthetic anticoagulant and an indanedione derivative. It prevents the formation of active procoagulation factors II, VII, IX, and X, as well as the anticoagulant proteins C and S, in the liver by inhibiting the vitamin K–mediated gamma-carboxylation of precursor proteins.

Erythro-Guaiacylglycerol β-dihydroconiferyl ether is extracted from Canadian maple syrup with potential antioxidant activity that can be used in the study of nutraceuticals.

4-O-Galloylbergenin shows significant 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging activity with EC50 7.8 uM, it shows more antioxidant activity than the positive control vitamin C (EC50 = 28.3 uM).

2-O-β-D-Glucopyranosyl-L-ascorbic acid (AA-2βG), isolated from Lycium Fruit, is a stable vitamin C analog with anti-tumor activity.

L-Dehydro Ascorbic Acid is the reversibly oxidized form of ascorbic acid;Dehydroascorbic acid ((L)-Dehydroascorbic acid), a blood-brain barrier transportable form of vitamin C, mediates potent cerebroprotection in experimental stroke.
