l-ascorbic acid

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

L-ascorbic acid 2-phosphate (Vitamin C phosphate) is a stable and long-lasting vitamin C derivative that stimulates collagen formation and has potential antioxidant capacity. L-ascorbic acid 2-phosphate is commonly used to promote osteogenic differentiation of human adipose stem cells (hASCs) in cell culture by increasing alkaline phosphatase (ALP) activity and runt-related transcription factor-2-DNA(runx2A) expression.

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.

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.

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-Ascorbic acid 6-stearate, a compound derived from L-ascorbic acid and stearic acid identified in K. coccinea, exhibits antioxidant and anticancer properties. It effectively scavenges DPPH radicals in cell-free assays (IC50 = 3.31 µg/ml). Additionally, lipid nanoparticles (LNPs) containing L-ascorbic acid 6-stearate have been shown to trigger apoptosis in HL-60 promyeloblasts at a concentration of 190 µM. This compound is also incorporated into cosmetic and personal care product formulations due to its beneficial effects.

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.

L-Threonic acid Calcium Salt is an anti-osteoporotic that stimulates ascorbic acid absorption and is commonly used in calcium supplements.

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.
