Merck, 95209-250G, L-Ascorbic acid

General description
L-Ascorbic acid, also known as vitamin C, is a water-soluble vitamin. It is naturally present in a variety of foods such as citrus fruits and vegetables. It is present only in minimal amount in milk.
Application
L-Ascorbic acid has been used as an antioxidant supplement in incubation solution for dissected and sliced brain sections. It has also been used as a supplement in phosphate-buffered saline (PBS) wash buffer during oxidative GFP chromophore formation.
Biochem/physiol Actions
L-Ascorbic acid (Vitamin C) acts as a potential anti-oxidant and reducing agent. It prevents bacterial mutagenesis induced by N-nitroso compounds. In plants, vitamin C elicits several cellular processes such as growth, apoptosis, pathogen responses, hormone responses, flowering and senescence, and protection against environmental stresses. Vitamin C deficiency is associated with the development of scurvy, prominent - gingivitis, perifollicular hemorrhages, poor wound healing, petechiae and ecchymosis.
