3 - The main use of glycyrrhizic acid is as a raw material for external use. It has many effects in the field.

Glycyrhizic acid has the ability to heal, antiseptic and protect the skin. It is often used for external ointment, powder, etc. Because it can help the inflammation of the skin, and can solve skin diseases such as rash and dermatitis. If the skin suffers from rash and rash, it can be applied with a product containing glycyrhizic acid, which can clear the skin and relieve it, stop it, collect it, and promote the recovery of patients.
It is also beneficial in ophthalmology. It can be used to treat eye pain and eye pain. Because it can clear the eyes, remove the shade, and make the eyes refreshing.
And in ancient times, those who know its effectiveness will know its effectiveness. With its compatibility, it is used for various skin and eye diseases. In the past month, its effectiveness has been obvious. Today, it is still widely used in the past. Glycyrrhizic acid, with its natural characteristics, is more complex and synthetic, with less side effects, and is more beneficial to patients. Therefore, its role in the field of external use is important, and it is also a good material for relieving patients' skin and eye pain.

3-Hydroxybutyric acid, also known as β-hydroxybutyric acid, is one of the ketone bodies in the human body. Its physical properties are quite unique, as detailed below:
Looking at its properties, under room temperature and pressure, 3-hydroxybutyric acid appears as a colorless to light yellow liquid, with a clear and fluid appearance, like a clear spring, free of precipitation and impurities. Looking at it gives people a sense of clarity.
Smell its smell, this substance emits a weak and specific smell, but it is by no means pungent and intolerable. It is similar to a slight sour gas, but it is different from the common pungent sour taste such as acetic acid. It needs to be sniffed carefully to detect, just like the unique smell hidden in the subtleties.
When it comes to solubility, 3-hydroxybutyric acid exhibits good water solubility and is highly soluble in water. It is as natural and smooth as salt into water, and can be mutually soluble with water in any ratio to form a uniform and stable solution. This property makes it easy to transport and participate in biochemical reactions in human physiological environments. At the same time, it also has certain solubility in some organic solvents, such as ethanol and acetone, which facilitates its application in different chemical scenarios.
Check its melting point and boiling point. The melting point of 3-hydroxybutyric acid is about -46 ° C, and the boiling point is between 208-210 ° C. The lower melting point makes it exist as a liquid at room temperature, while the relatively high boiling point indicates that it has a certain thermal stability. It is not easy to evaporate and dissipate easily in the general temperature fluctuation environment, and can maintain its own liquid stable state.
As for the density, the density of 3-hydroxybutyric acid is slightly larger than that of water, about 1.01-1.03g/cm ³. Although it is similar to the density of water, it has a unique distribution and behavior in the liquid mixture system, and has a significant impact on some physical separation processes.

3-Tyrosine acid, also known as levodopa, is an important chemical compound with polymorphism.
Its chemical formula is C, H, and NO, and the molecule contains benzene, amino, carboxyl and alkyl groups. In this way, it is given its specific physical and chemical properties. Due to its acidic nature, it is weakly acidic because it contains carboxyl groups, and can generate reactions and generate phase reactions. The same amino group makes it have certain properties and can react to acids. This property makes 3-Tyrosine acid exist in different forms under different acid environments.
3-Tyramine acid is highly reactive, and has a molecular polymorphism. This property affects its solubility and solubility in water, and is soluble in non-reactive water. Furthermore, the reactive group on benzene is prone to oxidation and reaction. In the air, especially in case of oxidation, the reactive group is easily oxidized, causing the molecule to change and affect its function.
In addition, the amino group of 3-tyramine acid can be reactive and reactive to form an amide derivative. The carboxyl group can be esterified and reactive, and the alcohol can be catalyzed to form an ester compound.
This chemical property makes 3-tyrosine acid very important in this field. Because it can cross the blood barrier before dopamine synthesis, it is used to treat neurological diseases such as Parkinson's disease, thereby improving the functional impairment of patients.

3 - The best way to show the powder, there is a wonderful way in ancient times, and now you have described it.
One method is to take the amount of soluble powder and make a thin paste with less cold water, so that it is even, do not make it. Take another amount of water, boil, put the powder paste into the boiling water, and cook for a while, until the solution is transparent and the powder is ready. It should be noted that the cooking should not be done for a long time, regardless of its nature or quality, affecting its effectiveness in processing and other things.
Another method is to first mix the powder and water in a certain proportion, put it in the research, and study it to make it fully blend. Then move to the kettle, add heat over low heat, and continue to mix until it is a homogeneous paste. This can also be used to show the powder. In this process, pay attention to the size of the fire and the speed of mixing. If the fire is fierce and easy to coke, the mixing is slow and uniform.
Then, the amount of powder such as chlorination is co-soluble in water, and a little degree is added to make the dissolution homogeneous. The addition of this powder may help to determine the performance of the product, but the dosage is controlled with precision, more or less. When it is completely dissolved and cooled, the powder is ready, and it can be used for the phase reduction of iodine and the like. The effect of its color is clearly discernible.

3-Hydroxyproline needs to be treated with caution during storage and transportation.
It is delicate and afraid of high temperature baking. If it is placed in a high temperature place, its molecular structure may be damaged, resulting in damage to its quality. When storing, when looking for a cool and dry place, the temperature should be controlled in a specific range to prevent deterioration. And it needs to be protected from direct sunlight, and light and heat will also induce adverse reactions.
3-Hydroxyproline is quite sensitive to humidity. Excessive ambient humidity can easily cause it to absorb moisture, or agglomerate, or cause mildew, which seriously affects its quality and utility. Therefore, where it is stored, the humidity must be strictly controlled, and desiccants and other substances can be prepared to maintain the dryness of the environment.
When transporting, packaging is crucial. It needs to be packaged with a well-sealed and suitable material to avoid excessive contact with the external environment and prevent it from being contaminated or deteriorated. And when handling, the action should be gentle, and it should not be violently vibrated or collided to prevent the packaging from being damaged, causing 3-hydroxyproline to be exposed and deteriorated in contact with air, moisture, etc.
In addition, 3-hydroxyproline may have certain chemical activity and should not be stored or mixed with corrosive substances such as strong acids and alkalis to avoid chemical reactions and cause it to fail. At the same time, different batches of 3-hydroxyproline should also be properly distinguished for easy traceability and management. In this way, extra attention should be paid during storage and transportation to ensure the quality of 3-hydroxyproline.
