Why are vitamin C tablets acidic and vitamin C acidic?

Here's why: vitamin C

The structure resembles glucose.

It is a polyhydroxy compound, and the two adjacent enol-type hydroxyl groups in the 2nd and 3rd positions of its molecule are easy to dissociate and release H+, so it has the nature of acid, also known as ascorbic acid.

Vitamin C is a water-soluble vitamin.

This means that its storage in our body is limited and needs to be replenished from time to time. The most familiar method for ordinary people is to eat more fresh fruits and vegetables, and young people are more willing to choose to use vitamin C effervescent tablets.

Ways of supplementing nutrients.

Either way, it is taken orally, so certain dietary guidelines should be followed.

Vitamin C is a kind of hexacharaldo acid, which has the effect of antiscorbemia, so it is called ascorbic acid, mainly reduced and dehydrogenated, widely found in plant tissues, fresh fruits and vegetables, especially dates, peppers, bitter gourd, persimmon leaves, kiwifruit, citrus and other foods are more abundant. It is one of the oxidoreductases, which is easily oxidized by itself, but is also an antioxidant under some conditions.

If you're referring to the taste of vitamin C tablets, the acid is because the excipients used to make vitamin C tablets are starch, dextrin, tartaric acid, distilled water, ethanol, and magnesium stearate, which are the ones that make the acid.

Because vitamin C (English: vitamin C, also known as L-ascorbic acid) is an acidic hexose derivative, it is a dilute alcohol hexolactone. VC is mainly fresh fruits and vegetables and is an essential nutrient for higher primates and a few other organisms.

VC has two isomers, L-type and D-type, only L-type has physiological functions, and both reduced and oxidized forms have physiological activities.

It is best known that vitamin C deficiency can cause scurvy. In living organisms, vitamin C is an antioxidant that protects the body from the threat of free radicals, and vitamin C is also a coenzyme.

Vitamin C is acidic and is found in higher levels in fresh fruits and vegetables, especially fresh dates, which have a sour taste, right? That's because of the high content, with the extension of storage time, the content of vitamin C will continue to decrease, and you will not feel the sour taste when eating. Many vegetables and fruits that contain vitamin C do not have a sour taste, and the same is true.

This is because vitamin C is an acidic nutrient, and some of the excipients in vitamin C tablets are also acidic.

The structure of vitamin C is similar to glucose, and it is a polyhydroxyl compound in Bai, and the two adjacent enol-type hydroxyl groups in the 2nd and 3rd positions of its molecule are easy to dissociate and release H+, so it has the properties of an acid, also known as ascorbic acid.

Vitamin C tablets contain starch, dextrin, tartaric acid, distilled water, ethanol, and magnesium stearate, which are responsible for the acid. It is recommended not to eat too much, and it is good to eat more fruits as a supplement.

Vitamin C tablets, also known as ascorbic acid, are acidic.

Are tablets acidic? A case of fakes (half-truths).

Problem description: Is vitamin C acidic?

Vitamin C lozenges are all sour, and green peppers contain a lot of vitamin C, so why aren't green peppers sour?

Analysis: The scientific name of vitamin C is: ascorbic acid

is acidic. 1 Vitamin C lozenges are concentrated tablets of vitamin C, which have a high concentration and therefore feel acidic.

2 The concentration of vitamin C in green peppers is much lower than that in vitamin C lozenges, so you don't feel acid.

Fruits that are not acids contain vitamin C.

Although vitamin C is originally ascorbic acid, it does not mean that acidic foods have vitamin C, and some foods rich in vitamin C, such as fruits and vegetables, have a sour taste that is produced or dominated by other organic acids, and vitamin C itself is acidic, but not very acidic.

Common fruits containing vitamin C mainly include: dates, kiwifruit, longan, tomatoes, sea buckthorn, grapefruit, strawberries, oranges, papayas, oranges, persimmons, mangoes, lemons, pineapples, pomegranates, bananas, pears, watermelons, grapes, coconut, apricots, hawthorns, etc.

Be. Vitamin C, also known as ascorbic acid, is weakly acidic, and the acidic H is the H (red part) on the top 2 of the structural formula

Acidic, vitamin effervescent tablets, especially vitamin C effervescent tablets contain acidic ingredients, which are processed with vitamin C, citric acid, sodium bicarbonate and glucose as raw materials.

It is acidic, and vitamin C itself is an organic acid - L-ascorbic acid.

Detoxification, help the body detoxify, and at the same time is also good for **. But don't overdo anything.

Yes, the following is the information.

Chinese name: L-ascorbic acid (ascorbic acid; Vitamin C) English name: L-ascorbic acid (vitamin C) molecular formula: C6H8O6

Molecular weight: physical and chemical properties: This product is white crystalline or crystalline powder, melting point 190 192; Odorless, sour taste; The color fades yellowish for a long time. This product is soluble in water, slightly soluble in ethanol, and insoluble in chloroform or ether.

The pH of 5% (W V) aqueous solution of this product is +, and the specific rotation of 10% (W V) aqueous solution of this product is +.

Quality Standards: Chinese Pharmacopoeia 2000 Edition Part II.

5% (W V) aqueous solution pH, acidity is not weak at all.

Acetic acid has a minimum pH of about 3, then it is acidic:

Ascorbic acid, acetic acid, carbonate, phenol.

Because vitamin C, also known as ascorbic acid, is colorless crystal, vitamin C due to the acidity of the part that makes up its structure, most of the vitamin C is metabolized and decomposed into oxalic acid in the body, so the taste is sour, sulfuric acid combined to generate ascorbic acid-2-sulfate vitamin C belongs to hexouronic acid, has the effect of anti-vitamin C deficiency, soluble in water, and has strong reducing properties.

The general vitamin C medicine removes the outer layer of sugar, and the inside is sour, and you can taste it yourself, and vitamin C can be held in your mouth.

It seems to be sour, I took vitamin C pills a long time ago.
