Ascorbic acid exists as two enantiomers (mirror-image isomers), commonly denoted "l" (for "levo") and "d" (for "dextro"). The l isomer is the one most often encountered: it occurs naturally in many foods, and is one form (" vitamer ") of vitamin C , an essential nutrient for humans and many animals.
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] Sodium ascorbate normally provides 131 mg of sodium per 1,000 mg of ascorbic acid (1,000 mg of sodium ascorbate contains 889 mg of ascorbic acid and 111 mg of sodium).
[72] l-Ascorbic acid has a negative feedback on l-galactose dehydrogenase in spinach. [93] Ascorbic acid efflux by embryos of dicot plants is a well-established mechanism of iron reduction and a step obligatory for iron uptake. [a] All plants synthesize ascorbic acid.
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.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Erythorbic acid (isoascorbic acid, D-araboascorbic acid) is a stereoisomer of ascorbic acid . [1] It is synthesized by a reaction between methyl 2-keto- D -gluconate and sodium methoxide . It can also be synthesized from sucrose or by strains of Penicillium that have been selected for this feature. [ 2 ]
Calcium ascorbate is a compound with the molecular formula CaC 12 H 14 O 12.It is the calcium salt of ascorbic acid, one of the mineral ascorbates.It is approximately 10% calcium by mass.
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.
