Potassium ascorbate is a compound with formula KC 6 H 7 O 6. It is the potassium salt of ascorbic acid and a mineral ascorbate. As a food additive, it has E number E303, INS number 303. Although it is not a permitted food additive in the UK, USA and the EU, [2] [3] it is approved for use in Australia and New Zealand. [4]
c 6 h 7 o − 6 + l• → c 6 h 6 o 6 • − + lh Loss of an electron from semidehydroascorbate to produce the 1,2,3-tricarbonyl pseudodehydroascorbate is thermodynamically disfavored, which helps prevent propagation of free radical chain reactions such as autoxidation : [ 6 ]
Intravenous Ascorbic Acid or PAA, pharmacologic ascorbic acid [1] (also known as vitamin C or L-ascorbic acid), is a process that delivers soluble ascorbic acid directly into the bloodstream. It is not approved for use to treat any medical condition.

Sodium ascorbate is one of a number of mineral salts of ascorbic acid (vitamin C). The molecular formula of this chemical compound is C 6 H 7 NaO 6. As the sodium salt of ascorbic acid, it is known as a mineral ascorbate. It has not been demonstrated to be more bioavailable than any other form of vitamin C supplement. [2]
An example of a mineral ascorbate drug is sodium ascorbate injections, as the acid form (ascorbic acid) of vitamin C is too acidic for injections). Ascorbate salts may be better tolerated by the human body than the corresponding weakly acidic ascorbic acid. Ascorbates are highly reactive antioxidants used as food preservatives. [2]
Dehydroascorbic acid (DHA) is an oxidized form of ascorbic acid (vitamin C). It is actively imported into the endoplasmic reticulum of cells via glucose transporters. [ 1 ] It is trapped therein by reduction back to ascorbic acid by glutathione and other thiols . [ 2 ]
Ascorbate peroxidase (or L-ascorbate peroxidase, APX or APEX) (EC 1.11.1.11) is an enzyme that catalyzes the chemical reaction. L-ascorbate + H 2 O 2 dehydroascorbate + 2 H 2 O. It is a member of the family of heme-containing peroxidases.
