Ascorbic Acid Powder for Sale Description

Vitamin C is a polyhydroxy compound with the chemical formula C6H8O6. The structure is similar to glucose, and the two adjacent enol hydroxyl groups on the 2nd and 3rd positions in the molecule are easily dissociated to release H+, so it has the property of acid, also known as L-ascorbic acid. Vitamin C has strong reducibility and is easily oxidized to dehydrovitamin C, but its reaction is reversible, and ascorbic acid and dehydroascorbic acid have the same physiological function, but if dehydroascorbic acid is further hydrolyzed, it will generate diketone ancient. laconic acid, the reaction is irreversible and the physiological efficacy is completely lost. Dietary sources of vitamin C are widely present in fresh vegetables and fruits. Tomatoes, cauliflower, bell peppers, dark leafy vegetables, bitter gourd, citrus, grapefruit, apples, grapes, kiwi fruit, fresh dates, etc. are rich in vitamin C.

Functions of Ascorbic Acid Powder

  1. Promote the biosynthesis of collagen, which is conducive to the faster healing of tissue wounds.

  2. Promote the metabolism of tyrosine and tryptophan in amino acids and prolong the life of the body.

  3. Improve the utilization of iron, calcium and folic acid; improve the metabolism of fats and lipids, especially cholesterol, and prevent cardiovascular diseases.

  4. Promote the growth of teeth and bones, prevent gum bleeding, prevent joint pain, low back and leg pain.

  5. Enhance the body's ability to resist stress and immunity to the external environment.

  6. Water-soluble strong antioxidant, mainly acts in aqueous solution in the body.

  7. Strengthens connective tissue; promotes collagen synthesis and prevents bleeding gums.


Applications of Vitamin C Powder Supplement

  1.  Pure scorbic acid powder can be applied in the cosmetic field to improving skin whitening.

  2.  It is a raw material of healthcare products.

About Vitamin C Ascorbic Acid Powder

  • Character

Vitamin C is a white crystal or crystalline powder, odorless, sour, and gradually turns yellowish after a long time. Soluble in water, acidic, slightly soluble in ethanol, insoluble in chloroform or ether. [3]

  • Acidic

The molecular structure of vitamin C has an enediol structure. Due to the influence of conjugation, C2-OH is very weak in acidity (pK2=11.57), and C3-OH is more acidic (pK1=4.17), so vitamins generally behave as monoacids , can act as a sodium salt with sodium bicarbonate.

  • Optical rotation

The molecular structure of vitamin C contains 2 chiral carbon atoms, so it has optical activity. According to the law (ChP2015 general rule 0621), the specific rotation of the aqueous solution containing 0.10g/mL of this product is +20.50°~+21.50°.

  • Reducibility

The enediol group in the molecular structure has a strong reducibility and is easily oxidized into a diketone group to become dehydroascorbic acid. Dehydroascorbic acid can be further hydrolyzed in alkaline solution or strong acid solution to form diketogulonic acid. and lose activity.

  • Hydrolyzability

The action of vitamin C and sodium carbonate can generate monosodium salt without hydrolysis, and the lactone ring becomes stable due to the double bond, but in strong alkaline solution, the lactone ring can be hydrolyzed to generate keto acid salt.

  • Properties of sugars

The structure of vitamin C is similar to that of sugar, so it has a carbohydrate-like reaction.
