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.

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.

Other Notes

Under conditions that are optimum for DbetaH, ascorbic acid denatures serum albumin, gamma-globulin, catalase, and DbetaH. With ascrobate plus Cu2+, the proteins are almost completely destroyed. Pyrazole protects DbetaH and albumin, but not catalase. Superoxide dismutase (SOD) is not denatured
