[(3S)-3-Amino-3-Carboxypropyl]{[(2S,3S,4R,5R)-5-(6-Amino-9H-Purin-9-Yl)-3,4-Dihydroxytetrahydrofuran-2-Yl]Methyl}Methylsulfonium 4-Methylbenzenesulfonate (Non-Preferred Name)

The chemical structure of this substance is formed by the connection of atoms in a specific way. Its structure characterizes the many properties of the substance, which is crucial to understanding its performance in various chemical reactions.
The structure of the material, there are elements such as the type of chemical bond between atoms, bond length, bond angle, etc. Chemical bonds, the interaction between atoms, maintaining the atoms in the structure. Covalent bonds, two atoms share electrons, and ionic bonds are formed by the atom's gain and loss of electrons, resulting in the attraction of anions and cations.
Take a common organic compound as an example, methane ($CH_4 $), whose structure is tetrahedral. The carbon atom occupies the center, and the four hydrogen atoms occupy each vertex. Carbon and hydrogen are connected by covalent bonds, and the bond length and bond angle have fixed values. This specific structure makes methane stable to a certain extent, and it is gaseous under normal conditions, and its chemical properties are relatively stable.
Another example is water ($H_2O $), whose structure is V-shaped. The oxygen atom is centered, and the two hydrogen atoms are separated on both sides. Oxygen and hydrogen are also connected by covalent bonds. Because the electronegativity of oxygen is greater than that of hydrogen, the electron cloud is biased towards oxygen, and the water-causing molecules are polar. This polar structure gives water unique properties such as high boiling point and good solubility.
As for complex macromolecules, such as proteins, their structures are complex. The primary structure is an amino acid sequence, which is connected by peptide bonds. The secondary structure includes alpha-helix, beta-fold, etc., which are maintained by hydrogen bonds. The tertiary structure is the further coiling and folding of the polypeptide chain, which is maintained by a variety of interactions. The quaternary structure is a combination of multiple subunits. This complex structure endows proteins with a variety of biological functions.
Importantly, the chemical structure of substances is complex and delicate, and the interaction between atoms and chemical bonds determines the properties and functions of substances. It is a key point in the study of chemistry and related disciplines.

There are many common uses of a substance, and today it is described by you.
In the realm of life, it can be used for daily use, which is convenient for everyone to live. For example, when you are at home, you can use it to make utensils, or dishes, or tables and chairs, which are sturdy and durable, making life more convenient and comfortable.

It is indispensable in the thing of construction. Use it to build houses, build walls and walls, make the house strong and stable, and can withstand the wind and rain, shelter the world from the wind and rain, and become a place to live.
It can also play a role in war. Build weapons and armor, add combat power to the soldiers, protect the home and the country, and protect the peace of one side.
Furthermore, in the ritual of sacrifice, it can also be seen. Made into ritual vessels, it is solemn and solemn, carrying people's reverence and prayers for the gods of heaven and earth, ancestors and ancestors, making the sacrificial ceremony more grand.
In short, this substance has common uses in life, labor, construction, war, sacrifice and many other aspects, and is closely related to the lives of the world. It plays an important role in the long history and promotes the development and progress of society.

The physical properties of a substance are related to its shape, color, odor, density, melting point, boiling point, hardness, solubility, and many other aspects. The following is described in Wenyan.
The form of a male object is either a solid state, with a solid texture and a fixed body; or a liquid state, flowing but amorphous, which can be shaped with the device; or a gaseous state, ethereal and invisible, filling the four directions. The colors are colorful, red-orange, yellow-green, blue-purple, each showing its own rhyme, such as gold and yellow, silver and plain white, copper and red-brown. The smell is divided into fragrant and fragrant, and the orchid spits out, which is pleasant; the rot is filthy, and the smell is vomiting.
The density is related to the light, weight and density of things. In the ratio of water, the heavy one sinks, and the light one floats. Such as the genus of iron stone, the density is greater than that of water, and it sinks when thrown into water; if the wood material is less dense than water, it can float on blue waves. Melting point and boiling point are the key to the change of the state of matter. When heated, it melts from solid to liquid, which is the melting point; when heated and boiled, it changes from liquid to gas, which is the boiling point. Different substances have different melting points. For example, the melting point of ice is zero degrees Celsius, and the melting point of iron is very high. It takes more than a thousand degrees to melt.
Hardness is related to the firmness and brittleness of things. The genus of gold and stone is quite hard and can be engraved on other things; while plasters and the like are soft and easy to deform. Solubility is also an important physical property, and things may be soluble or insoluble in water. Salt and sugar are easily soluble in water, dissipating and invisible; while the quality of sand and stone is difficult to dissolve in water and cannot be immersed for a long time.
All these physical properties are essential for identifying things. Knowing this, the nature of all things can be obtained in detail, and it can be handy in the matter of creating things with things.

Today there is a thing, I want to know how to make it. This thing is related to the creation of heaven, so it is said in ancient Chinese.
When you make this thing, the first thing you need to do is to choose the materials. You need to look at the products produced in various places, and choose the ones that are good. If the materials are not suitable, it will be difficult to achieve success. For example, when building a boat, you must choose a tough wood, so that you can ride the waves in the water.
At the beginning of its making, you must first apply your skills to the materials. Whether you chop or cut, you can make it rule. The measure here is all based on the eyes and ingenuity of the craftsman. Such as the work of carving jade, carefully inspecting the texture of the jade, according to the shape and the situation, you can get beautiful tools.
Then, according to the shape of The size and duration of a fire are all determined. If the fire is large, the material will be destroyed, and if the fire is small, the work will not be completed. It is like the art of burning porcelain. The kiln temperature is moderate, and the porcelain is complete.
Furthermore, when assembling, you need to be careful. The parts must be in perfect harmony, otherwise the function of the thing will be greatly reduced. If you make a mechanical crossbow, the machine is connected, and there is a slight difference, you cannot make an arrow.
In the meantime, the craftsman should have a heart of awe and focus on it. Making things is not easy, a little negligence, and all previous efforts will be lost. The ancient good work, every thing made, must be reviewed repeatedly, and the service period will be perfect.
In this way, with excellent selection of materials, skilled skills, proper heat, exquisite assembly, and a dedicated heart, this thing can be achieved. Although it is simple, the way of making things is roughly here.

When using this item, many matters need to be paid attention to.
Safety is the first priority, this is the most important. This item may be dangerous, such as sharp edges, high temperature parts, electrical hazards, etc. Be sure to read the usage guide carefully before use to clarify the correct operation method to avoid accidental injuries. If you handle a sharp blade, be careful not to slip and hurt people; play with electrical appliances, beware of the risk of electric shock.
Furthermore, the use environment cannot be ignored. It is necessary to choose a suitable place, and do not use it in places with humidity, high temperature, and strong earthquakes. Humidity is easy to rust and short circuit; high temperature or damage the performance of components; strong earthquakes may cause parts to loosen and damage. Such as precision instruments, it is easy to lose accuracy when used in bumpy places.
Third, the frequency and duration of use also need to be controlled. Excessive use or premature wear and tear will reduce the lifespan. Use should be reasonably arranged according to its design specifications. If the mechanical device runs continuously for too long, it is easy to cause overheating and wear.
Fourth, properly maintain and maintain it after use. Cleaning, lubrication, tightening and other steps are indispensable. Timely cleaning can remove dirt impurities and prevent their erosion; regular lubrication can reduce friction loss; check fastening to ensure that the parts are stable. If the sword is used up, wipe and maintain it before it can be sharp for a long time.
Finally, the user should also have the corresponding skills and knowledge. Untrained, ignorant and ignorant, use rashly, prone to mistakes. Only by learning and practicing and mastering the operation skills can it be used. In this way, it is necessary to make good use of this thing, exert its effectiveness, and ensure safety.
