Niche, non-food uses. Ascorbic acid is easily oxidized and so is used as a reductant in photographic developer solutions (among others) and as a preservative. In fluorescence microscopy and related fluorescence-based techniques, ascorbic acid can be used as an antioxidant to increase fluorescent signal and chemically retard dye photobleaching.
Ascorbic acid is a weak sugar acid structurally related to glucose. In biological systems, ascorbic acid can be found only at low pH, but in neutral solutions above pH 5 is predominantly found in the ionized form, ascorbate. All of these molecules have vitamin C activity and thus are used synonymously with vitamin C, unless otherwise specified.

Ascorbic acid (ascorbate, vitamin C) is a simultaneously well-known and surprisingly poorly-understood compound. It is synthesised only by eukaryotes and, to date, chemical analyses have not provided strong evidence for its synthesis by prokaryotes.
Ascorbic acid is an odorless, colorless, acidic, solid and soluble element. Structure. The chemical formula of ascorbic acid is C6H8O6, and its molecular weight is 176.12 grams per molecule. Its exact melting point is at 192 degrees Celsius, and the low temperatures break it down. Acidity.
Ascorbic acid (AsA) is a major antioxidant and plays an important role in plant growth and development. There are two aspects to improve AsA content, including de novo synthesis and recycling from its oxidized form. However, the knowledge of regulatory mechanisms of AsA synthesis pathways and metabolism still remains limited.
Vitamin C has a rich and surprisingly controversial history. On the one hand, science is clear that the body needs it, but the type, dose, and frequency are all up for debate. When the common cold is making the rounds, many people turn to vitamin C, also known as ascorbic acid, to help ward off illness. Without it, immune system function declines.
Ascorbic acid (vitamin C) is a water soluble vitamin found widely both in the plant and animal kingdoms. It is of major importance in human nutrition and maintenance of good health. Current world production is estimated at approximately 80,000 metric tons per year with a world wide market in excess of $600 million.
/ Ascorbic Acid: Vitamin C For The Kitchen The history of ascorbic acid (or vitamin C) as a food additive began with the identification of vitamin C deficiency, also known as scurvy. A British naval surgeon named James Lind was the first to identify the benefits that citrus could have for people suffering from vitamin C deficiency.
Vitamin C vs. Ascorbic Acid. It's really important to get this straight, right off the bat. Vitamin C and ascorbic acid are two different substances. That distinction can be confusing, especially because if you walk down the pharmacy aisle, or even check the supplements in a health food store, you're going to see the two used interchangeably on some labels.

I use both for my all in one mix the Ascorbic acid keeps the ph to a level stopping the iron participating out (below a ph of 6 ) the potassium Sorbate stops the mixture from moulding so I think you could use the potassium Sorbate to stop the moulding in your ATO and even if it does not work it wont harm any thing at that small a dose as long as the water in the ATO Is at a ph of lower than 6 ...
Ascorbic acid, als o known as Vitamin C, is a water-soluble vitamin necessary for normal growth, development and repair of damaged tissues in the body. It is essentially an antioxidant which is needed for the prevention of some of the damage done when one is exposed to cigarette smoke, radiation or when the body breaks down food.
Prepare the ascorbic acid. For several pounds of fruit, use a large pot and combine 1 tsp. ascorbic acid (powder or crushed tablets) with 1 gallon distilled water. You may need to use several tablespoons of the store-bought mixture depending on the amount of fruit you are preparing and the manufacturer's instructions.
Ascorbic acid (vitamin C) is an abundant component of plants. It reaches a concentration of over 20 mM in chloroplasts and occurs in all cell compartments, including the cell wall.
Find patient medical information for Ascorbic Acid (Vitamin C) Oral on WebMD including its uses, side effects and safety, interactions, pictures, warnings and user ratings.
Ascorbic acid (AsA), vitamin C, is one of the most abundant water-soluble antioxidant in plants and animals. In plants AsA serves as a major redox buffer and regulates various physiological processes controlling growth, development, and stress tolerance.
Store ascorbic acid at room temperature away from moisture and heat. Do not stop using ascorbic acid suddenly after long-term use at high doses, or you could have "conditional" vitamin C deficiency. Symptoms include bleeding gums, feeling very tired, and red or blue pinpoint spots around your hair follicles.
Subject: Draft Final Report on Ethers and Esters of Ascorbic Acid A tentative report with a conclusion stating that 7 ethers and esters of Ascorbic Acid are safe in the present practices of use and concentration described in the safety was issued at the December 5-6 Expert Panel meeting. Comments on the tentative
The chemical properties of ascorbic acid provide a wide range of industrial applications. The uses of ascorbic acid or vitamin C depend on its chemical properties as an antioxidant or on its health-related properties. About one-third of total production is used for vitamin preparations in the ...
This published clinicial article supports our use of a completely WATER FREE base for our vitamin C+ Firming serum.It also supports our our use of Ferulic Acid, (in our F*a*C*E Synergy serum) to boost the effectiveness and stabilize the 20% C in that formula.
Ascorbic acid regulates cell division and growth and is involved in signal transduction. In contrast to the single pathway responsible for ascorbic acid biosynthesis in animals, plants use multiple pathways to synthesize ascorbic acid, perhaps reflecting the importance of this molecule to plant health.
What about high dose, intravenous ascorbic acid for the very ill? Note that vitamin C for IV use is almost always derived from GMO corn as well as being extremely high dose and synthetic ascorbic acid only. Under certain circumstances and for the very ill, high dose GMO ascorbic acid therapy can be beneficial.
Ascorbic acid efflux by embryo of dicots plants is a well-established mechanism of iron reduction, and a step obligatory for iron uptake. All plants synthesize ascorbic acid. Ascorbic acid functions as a cofactor for enzymes involved in photosynthesis, synthesis of plant hormones, as an antioxidant and also regenerator of other antioxidants.
L-ascorbic acid also called vitamin C, is a water soluble vitamin and acts as a reducing agent for various biochemical reactions. Ascorbic acid plays a key role in the production of collagen. Ascorbic acid is essential for neurodevelopment, neurotransmitter synthesis and modulates neuronal synapsis.
Ascorbic acid is an important water-soluble antioxidant in biological fluids. Ascorbic acid scavenges reactive oxygen and nitrogen species, such as superoxide, hydroxyl, nitroxide and aqueous peroxyl radicals, singlet oxygen, ozone, peroxynitrite, nitrogen dioxide, and hypochlorous acid.
