Which calcium acetate or calcium carbonate is easy to absorb?

The absorption effect of calcium acetate will be better.

Calcium acetate is an acetate of calcium, with the molecular formula Ca(CH3COO)2 or (CH3COO)2Ca, which is an organic salt and is easily absorbed.

Calcium carbonate is inorganic calcium, with a calcium content of 40%, insoluble in water, a small degree of ionization, and an absorption rate of 32%, which is not very suitable for children to absorb because it needs to consume a lot of gastric acid.

At present, there are many calcium preparations on the market, we divide them into inorganic calcium and organic calcium (the chemical formula contains C, H, O, CA is organic calcium, and the others are inorganic calcium), inorganic calcium is mainly represented by calcium carbonate, with high calcium carbonate content (40%), but low solubility (1mg 100ml), absorption needs to consume gastric acid, so that calcium is free to form calcium ions to be absorbed, because our body can only absorb calcium in the form of ions, so calcium carbonate, because there are no more calcium ions can be absorbed by the human body, Therefore, the absorption is not good, and the consumption of gastric acid will cause great harm to our gastrointestinal tract, I do not recommend the use of this type of calcium, although this type of calcium is very cheap.

The other type is organic calcium, organic calcium has a common characteristic, that is, the content is low, but the solubility is high, and the degree of gastric acid consumption depends on the solubility of various calcium agents. At present, there is a calcium supplement based on calcium acetate on the market, which I think is better. Calcium acetate is molecularly calcium acetate, which ranks first in organic matter, so its calcium content is currently the highest (25%) in organic calcium, and the solubility is also the highest (38500mg 100ml), so I recommend that you use calcium acetate, which is more conducive to absorption, and has no greater impact on gastric acid than calcium carbonate.

If calcium acetate is taken, it can be taken on an empty stomach in the morning and evening, as an empty stomach is best.

Calcium carbonate, the human body can only absorb ionic calcium, calcium carbonate can be completely absorbed into calcium ions under the action of gastric acid, and calcium acetate not only has a small percentage of calcium, and can not be completely hydrolyzed, but also dilutes the acidity of gastric acid, resulting in indigestion.

Of course, eating too much calcium carbonate will also cause stomach bloating, because carbon dioxide will be released.

Calcium acetate, calcium carbonate solids are not very absorbed.

By chemical composition:

Calcium organic acids: calcium acetate (Bangyu calcium), calcium gluconate.

Calcium inorganicates: calcium carbonate (calcium, liquid calcium).

Comparison of the absorption rate of calcium with the calcium content, the release of calcium in gastric juice and the body's demand for calcium

Calcium preparation Calcium content Degree of release in water (solubility) Degree of gastric juice release: Calcium carbonate 40% 6% (1mg l) 25% calcium acetate 100% (38500mg l) 100%.

You'd better go back and try it to see if calcium carbonate can be hydrolyzed, and to what extent calcium acetate is hydrolyzed.

Calcium carbonateThe reaction with acetic acid is: calcium carbonate and acetic acid react to form calcium acetate andCarbon dioxideand water reactionEquationsYes: CaCO3 + 2CH3COOH ==CH3COO)2CA + CO2 + H20.

Calcium carbonate is used in different places to have different effects, if it is used in the laboratory, calcium carbonate can be used to produce carbon dioxide, calcium carbonate can also be used as an additive in some foods. If it is in the paper industry and the construction industry, calcium carbonate is also used, calcium carbonate can be used to make gussets, plastics, cables, toothpaste paste, paints, and can also be used as feed additives.

Calcium carbonate and acetic acid chemical reaction.

The equation is: CACO +2ch COOH=CA(ch COO) +H O+CO

The ionic equation for the reaction of calcium carbonate with acetic acid.

caco₃＋2ch₃cooh＝ca₂＋＋2ch₃coo－＋h₂o＋co₂↑

Calcium carbonate meets dilute acetic acid and dilute hydrochloric acid.

Dilute nitric acid boils and dissolves. When heated to 900 kilopascals, it decomposes into calcium oxide and carbon dioxide.

Calcium carbonate is heated at a pressure of one atmosphere to 900 degrees Celsius, which will decompose into quicklime.

and carbon dioxide (industrially produced co):

Carboxyl hydrogen atom of acetic acid.

It can be partially ionized into hydrogen ions (protons) and released, resulting in the acidity of carboxylic acids. Acetic acid is a single weak acid in aqueous solution, the acidity coefficient is, pka=, and the pH of the acetic acid solution with a concentration of 1mol L (similar to the concentration of household vinegar) is, that is, only the acetic acid molecule is dissociated.

The chemical reaction equation of calcium carbonate and acetic acid is: CACO +2ch COOH=CA(CH COO) +H O+CO. The ionic equation for the reaction of calcium carbonate with acetic acid.

caco₃＋2ch₃cooh＝ca₂＋＋2ch₃coo－＋h₂o＋co₂↑。

1. Acetic acid is a relatively simple organic acid, and its acidity is weaker than hydrochloric acid, but the nature of the reaction with calcium carbonate here is the same, that is, the acid and carbonate have a complex imitation of the solution reaction.

2. Calcium carbonate and acetic acid react to form calcium acetate and carbon dioxide and water.

3. Uses of calcium carbonate:

1. Laboratory use:

1) It can also be used to produce carbon dioxide in the laboratory.

2) Characterization and determination of halogens in organic chemical reactions. Water analysis. Phosphorus is verified. Breaks down silicates together with ammonium chloride. Calcium chloride solution is prepared to standardize the soap solution. Manufacture of optical neodymium glass raw materials and coating raw materials.

2. Other uses:

1) It can be used as an additive in the food industry.

2) It is often used in the construction industry and the paper industry.

3) Within 200 mesh: It can be used for various feed additives with calcium content above and no harmful ingredients.

4. Calcium carbonate is solid, and it is a normal salt, which is not acidic and alkaline. If it is in an aqueous solution, because calcium carbonate is insoluble, it will only ionize a small amount of carbonate ions, so the degree of hydrolysis of carbonate in aqueous solution is not very large, but it will also be very weakly alkaline.

5. Acetic acid can be used as an acidity regulator, acidifier, pickling agent, flavor enhancer, spice, etc. It is also a good antimicrobial agent, mainly due to its ability to reduce the pH below the pH required for optimal microbial growth. Acetic acid is the earliest and most used acidulant in China, which is mainly used for compound seasonings, waxes, canned food, cheese, jelly, etc.

The equation for the reaction of calcium carbonate and acetic acid to produce calcium acetate and carbon dioxide and water is: CaCO3 + 2CH3COOH ==CH3COO)2CA + CO2 + H20, where CO2 should be marked with a gas symbol.

Acetic acid is a relatively simple organic acid, and its acidity is weaker than hydrochloric acid, but here it reacts with calcium carbonate in the same nature, that is, the acid and carbonate undergo metathesis reaction.

Calcium carbonate is mainly used

Laboratory use.

1.In the biological "extraction of pigment from green leaves" experiment, adding a little calcium carbonate during grinding can prevent the pigment from being destroyed during grinding.

2.Calcium carbonate has applications in the preparation of CaO, Ca(OH)2, and NaOH: calcium carbonate is calcined at high temperature to generate calcium oxide and carbon dioxide.

Milk calcium is easier to absorb.

It is the source of inorganic salts with the best nutritional value and is easy to digest and absorb. Because about 70% of the calcium in milk is in the state of casein colloids, including about 40% of colloidal calcium phosphate and about 30% of calcium bound to casein.

Milk calcium is recognized as the food-grade calcium supplement with the highest "bio-benefit rate" of all calcium, because milk calcium is moderately high and has a moderate amount of protein and a reasonable ratio of calcium to phosphorus2 1;At the same time, because there are no chemical components and processes in its production process, there is no burden on the gastrointestinal tract.

Everyone generally has a misunderstanding, always think that the more calcium you eat, the more calcium you absorb, in fact, the ratio of calcium:phosphorus should reach 1:2 is the best absorption ratio, remember, any chemical products that supplement calcium are not as effective as ingesting from things, such as the bone broth mentioned upstairs, which is very good.

There is also a misunderstanding, that is, the question of which age groups are suitable for calcium supplementation and how much:

Infants aged 0-5 years need calcium for children aged 5, 9-12 years and the elderly over the age of 14-20 years old.

Of course, if you want to buy calcium supplements, it is better to buy liquid calcium.

Calcium lactate is easier.

Whey calcium (lactocalcium), a whey inorganic salt concentrate, is the most nutritious source of inorganic salts and is easy to digest and absorb. The total inorganic salt content in milk is about about calcium, which is the best source of calcium compared with calcium in other foods, because about 70% of the calcium in milk is in the state of casein micelle, including about 40% of colloidal calcium phosphate and about 30% of calcium combined with casein. About 30% of the calcium in milk is soluble calcium, about 30% of the soluble calcium is ionic calcium, 60% is calcium citrate, and the remaining 10% is calcium phosphate.

Milk calcium is recognized as the most "bioavailable" food-grade calcium supplement of all calcium, because it also has the right amount of protein and a reasonable ratio of calcium to phosphorus2 1;At the same time, because there are no chemical components and processes in its production process, there is no burden on the gastrointestinal tract.

Lactic acid, of course! Calcium carbonate is a solid, and it has to react with hydrochloric acid in stomach acid before it can be absorbed by the body!

Milk calcium is best absorbed, this is for sure, so drink more milk. Calcium carbonate is more convenient, contained in key products, or food, in fact, if you are not partial to eating, you can absorb it in food.

Five-month-old baby is better to eat milk calcium or calcium carbonate, five-month baby's body resistance is not very strong, and the body function is not fully developed, so it is better for us to give five-month-old baby or milk calcium, because calcium carbonate still has a certain amount of acid, which may cause some harm to five-month-old baby. And the *** of milk calcium is the smallest.

It is better for five-month-old babies to eat milk calcium or calcium carbonate.

First of all, generally speaking, the calcium content in calcium carbonate is larger than that of milk calcium, but milk calcium is easier to be absorbed and utilized by the baby, the baby's gastrointestinal function is very fragile, it is best to choose milk calcium, because the baby does not need gastric acid to participate in the absorption of milk calcium, if the baby's gastrointestinal function is good, you can choose calcium carbonate.

Secondly, in fact, baby milk calcium can be eaten together with cod liver oil, because cod liver oil can promote calcium absorption, but the eating together here is not to eat cod liver oil immediately after eating milk calcium, but to give the baby cod liver oil in the morning and milk calcium to the baby at night, so as to achieve the best absorption effect.

Finally, the baby's development in infancy is very rapid, the growth of the baby's bones needs more calcium, many parents think that this time should give the baby to eat more calcium preparations, in fact, this approach is not very appropriate, food is the important baby calcium, the baby eats breast milk and milk powder is also rich in calcium, and food supplement is the healthiest way to supplement calcium.

Babies eat milk calcium or calcium carbonate is actually different for milk calcium and calcium lactate, the two are different concepts, of which milk calcium is a mixture made of natural milk through physics, mainly calcium citrate and calcium phosphate. Calcium lactate, on the other hand, is a pure substance that combines lactic acid and calcium ions. However, calcium carbonate is not good for babies with bad stomach, and stomach acid will appear.

So for babies it is better to have milk calcium.

Milk calcium is naturally refined from milk calcium, which is relatively easy to absorb, while calcium carbonate does not have such a high calcium content, and the absorption of milk calcium will be relatively poor. If some babies are not suitable for calcium carbonate, it will make the baby diarrhea in serious cases. Therefore, the choice should also be based on the baby's adaptability.

In fact, these two calcium supplements are okay, depending on which one the child is suitable for, but if the child is not deficient in calcium, do not supplement calcium.

Generally, it is better to supplement calcium carbonate to the baby, and calcium gluconate can also be supplemented. Babies at five months generally eat a little more calcium gluconate oral liquid, and at the same time, they can supplement the absorption of vitamin AD outbound calcium.

It is better to use calcium carbonate. Because calcium carbonate is chemically more active. In the human body, it is easier to decompose into elements that can be absorbed by the body. Therefore, the effect of using calcium carbonate for babies will be better.
