l ascorbic acid and d ascorbic acid are optical isomers of each other. Optical isomers have the same physical and chemical properties but bend the plane of polarisation of polarized light in different directions.
It is also called Chirality
See the related link for more info on optical isomers.
There is only one asymmetric carbon atom in ascorbic acid, hence the possibility of two enantiomeric forms; the L-enantiomer and the D-enantiomer.
The C in Vitamin C came from the name of the person who first discovered it: CharlieVitamin C is also known as L-ascorbic acid or L-ascorbate...The person responsibile for identifying vitamin C wasAlbert Szent-Györgyi, so vitamin C did not come from his name.

same here. I tried the calcium ascorbate but is not working. also u get too much of the nasty calcium but can chelate copper well because of acetone... After that try l-ascorbic acid with taurine and u will see the difference. nasty small yellow stones and big green gallstones are out without the need of gallbladdr flush with the epsom salt. I tried both and for sure l ascorbic acid & taurine is way better than epsom salt & olive oil.
The behavior against polarized light is different.
The scientific name for ascorbic acid is L-ascorbic acid.
The active form of ascorbic acid is called L-ascorbic acid, which is the naturally occurring form of vitamin C that is biologically active in the body.
L-ascorbic acid
Vitamin C is ascorbic acid. It is also referred to as ascorbate, L-ascorbic acid, or L-ascorbate.
There is only one asymmetric carbon atom in ascorbic acid, hence the possibility of two enantiomeric forms; the L-enantiomer and the D-enantiomer.
The equivalent weight of L-ascorbic acid is its molecular weight divided by the number of electrons gained or lost per molecule in a reaction. For L-ascorbic acid (C6H8O6), the molecular weight is 176.12 g/mol. During oxidation, L-ascorbic acid loses two electrons, so its equivalent weight is 88.06 g/mol.
Ascorbic acid L.

Needed table values (constants) for ascorbic acid, C6H8O6:pKa = 4.10 , molar mass = 176.12 g mol−1.Formula:pH = 0.5*{pKa - log(Ca)} , where Ca = ascorbic acid concentration in mol/L .Calculus:4.00 g/L Ascorbic acid (C6H8O6) = 4.00(g/L) / 176.12(g/mol) = 0.0227 mol/L Asc.acidpH = 0.5 * {4.11 - log(0.0227)} = 0.5 * {4.11 + 1.64} = 2.88 => about 2.9
Vitamin C is L-ascorbic acid, or simply ascorbate (the anion of ascorbic acid), is an essential nutrient for humans and certain other animal species.
Another name for C20 is d-Ascorbic acid or L-ascorbic acid, which is a form of vitamin C commonly used in skincare products for its antioxidant properties.
Yes, Vitamin C is an acid. It is actually called ascorbate or L-ascorbic acid. It is a type of necessary nutrient or vitamin in animals that is water-soluble.
