    Ascorbic acid is water-soluble and has a molecular mass of At physiological pH, ascorbic acid is present mainly as the ascorbate anion [1]. Ascorbate functions mainly as a water-soluble antioxidant and a cofactor of enzymes involved in biosynthetic reactions [2].Cited by: 8.

    Ascorbic acid supplements of 30 mg/d for 10 days failed to increase plasma ascorbate concentrations; 60 mg for 10 days caused a small increase and 90 mg/d resulted in a mean ascorbic acid concentration of 29 mmol/L. Erythorbic acid did not cause any adverse effects but rather had a small ascorbic acid-sparing effect. Vitamin C is defined as the substance that cures the deficiency disease scurvy. This separates the ascorbates from the ill-defined "natural vitamin C complex." Note that any "natural" complex, minus ascorbic acid, does not and cannot cure scurvy, and therefore, cannot be Vitamin C.

    Ascorbic acid is an organic compound with formula C 6 H 8 O 6, originally called hexuronic is a white solid, but impure samples can appear yellowish. It dissolves well in water to give mildly acidic solutions. It is a mild reducing agent.. Ascorbic acid exists as two enantiomers (mirror-image isomers), commonly denoted "l" (for "levo") and "d" (for "dextro").E number: E (antioxidants, ).

However taken together, the volume comprehensively covers the subject of ascorbic acid in aquatic organisms, with em-phasis on fishes. It is an important and useful compendium of information for fish (and shell-fish) nutritionists and culturists.

Vitamin C, or Ascorbic acid, is one of the most effective and safest nutrients. It is a water-soluble vitamin. It is a powerful antioxidant for the synthesis of collagen, which helps to make blood vessels and body muscles strong.

The human body doesn’t have the capacity to generate Vitamin C. Therefore, it needs to be received through food /5(). AA is the most powerful water-soluble antioxidant of the organism, and key to preventing oxidative lipid damage in biological systems [2].

It forms the first line of antioxidant defence under many types of oxidizing conditions. It can rapidly intercept free radicals in the aqueous phase before they attack lipids [3].Cited by: Second, vitamin C is not toxic to aquatic life at the levels used for dechlorinating water.

Although ascorbic acid is mildly acidic and, in large doses, will lower the pH of the treated water, sodium ascorbate is neutral and will not affect the pH of the treated water or the receiving stream.

Vitamin C also known as ascorbic acid (AA) is an essential nutrient in many multicellular organisms, especially in humans. Ascorbic acid is a water-soluble vitamin and is found in variable quantities in fruits and vegetables and organ meats (e.g.

liver and kidney).Cited by: 1. Ascorbic acid, which is exudated from plant roots, aquatic macrophytes and phytoplankton and also derives from decomposition of organic matter (e.g.

It is a commercial antioxidant, but cannot be utilized by the body as an essential nutrient. Acidity. That word "acid" gets us going, but in fact ascorbic acid is a weak. Later in Dabrowski prepared a full review for vitamin C in his book “Ascorbic acid in aquatic animals”. Chemical forms and its analogs Vitamin C exists in two forms, the reduced form (ascorbic acid) and the oxidized form (dehydroascorbic acid) (Figure 1).

Both have vitamin C activity but the one that predominates is the reduced form. Vitamin C (ascorbic acid (AA)) is very popular for its antioxidant properties. Consequently, many other important aspects of this multifaceted molecule are often underestimated or even by: The use of microorganisms in L-ascorbic acid production Article Literature Review in Journal of Biotechnology (1) July with 1, Reads How we measure 'reads'.

Ascorbic acid (vitamin C) is a water-soluble vitamin and a recognized antioxidant drug that is used topically in dermatology to treat and prevent the changes associated with photoaging, as well as for the treatment of hyperpigmentation.
