Organic acids in the life of each of us

Organic acids are natural substances with acidic properties that are in pure form in plants, and also take the form of salts or esters - organic compounds

In a free state, such polybasic hydroxy acids are kept quite often in fruits, while compounds are characteristic first of all for the remaining elements of plants like the stem, leaves, and so on. If you look at organic acids, the list of them is constantly increasing and in general is not closed, that is, regularly replenished. Already discovered are acids such as:

- Adipic,

-benzoic,

-dichloroacetic,

-valeric,

-glycolic,

Glutaric,

Is a lemon,

-maleic,

-Margarine,

- oil,

-dairy,

-monochloroacetic,

-form,

-propionic,

-salicylic,

-trifluoroacetic,

-fumaric,

-acetic,

-stable,

-blue,

-and many other organic acids.

Often such substances can be found in fruit and berry plants. Fruit plants include apricots, quinces, cherry plums, cherry plums, citrus fruits and apples, cherry, cherry, blackberries, cranberries, gooseberries, raspberries, black currants. They are basically based on wine, lemon, salicylic, oxalic and malic acids. Organic acids are also present in berries, including a lot of benzoic acid.

To date, many properties of acids have been studied directly in the field of pharmacology and biological effects on the human body. For example:

• First, organic acids - Sufficiently significant components of metabolism (metabolism, namely proteins, fats and carbohydrates);
• Secondly, cause the secretory work of the salivary glands; Promote acid-base balance;
• Thirdly, they take a significant part in increasing the separation of bile, gastric and pancreatic juices;
• And finally, are antiseptics.

Their acidity ranges from four whole pH values to five and five.

In addition, organic acids play an important role in the food industry, acting as a direct indicator of quality or poor quality of products. For the latter, the method of ion chromatography is very often used, in which not only organic acids, but also inorganic ions can be detected at a time. With this method, conductometric detection with a blanking of the background electrical conductivity shows the result almost ten times more accurate than detection at low wavelengths of ultraviolet radiation.
The identification of the profile of organic acids in fruit juices is necessary not only to establish the quality of the drink, its admissibility to consumption, but also contributes to the definition of forgery.
If we consider directly the properties of carboxylic acids, then, first of all, they are:

- giving red color to litmus paper;

- easy solubility in water;

- present sour taste.

Also, carboxylic acids are a fairly important electrical conductor. By the strength of the decomposition, absolutely all acids belong to a weak group of electrolytes, with the exception, naturally, of formic acid, which in turn occupies an average intensity value. The height of the molecular weight of the carboxylic acid affects the decay force and is inversely proportional. With the help of specific metals, it is possible to isolate hydrogen and salt from acids, which is much slower than when interacting with strong acids like sulfuric or hydrochloric acid. Salts also appear when exposed to basic oxides and bases.
