Xue'er is worried that Zhu Zhu will get in the way. Pen Fun Pavilion wWw. ｂiquge。 info Du Xiaomei was angry in her heart: "Hmph, she dares not to agree." Then he looked at Yang Siyu with a weak heart: "Eldest sister, why don't you go and tell me, it's a big deal that I apologize to her, okay, okay." Twisting Yang Siyu like a twisted flower.

Xue'er: "I'll talk about this, if it doesn't work, let Sister Siyu come out." However, the final decision is still in Mr. Yuan's hands, and when Mr. Yuan is busy with these two days' work, I will ask him. ”

Du Xiaomei: "He will definitely agree." ”

Cher: "Then we have to wait until he agrees." Silly girl, you can't wait for two days, right? Besides, Sister Lingjia also needs to be taken care of. ”

Du Xiaomei's face turned red all of a sudden. I almost forgot about Qi Lingjia, she still had to lie on the bed for a while.

Cher is really doing things. In less than half a day, she approved the identity cards of Yang Siyu's three daughters. Of course, she only needs to get the consent of her father, Mr. Jane, and it is not difficult.

As for obtaining Zhu Zhu's consent, it didn't take much effort. Zhu Zhu was busy helping Yuan Qidong work, and secretly took time to listen to Xue'er's request, and only then did he roughly understand the reason for the incident just now, and he couldn't help but be afraid for a while, and said secretly, this Mr. Yuan is really cold, and any kind of woman dares to take him in.

However, she is not Yuan Qidong's woman openly or secretly, and she can't offend people for inexplicable reasons, so naturally she won't obstruct it. And Xue'er is Mr. Jane's daughter, she came to know about this, maybe it is what Mr. Jian meant, so what else did Zhu Zhu say.

Xue'er got the consent of the two of them, and rushed to find the three girls, took them to make identity cards, pressed the hand mold, scanned the retina, and had to enter the password. It made the three girls dizzy. Although Qi Lingjia has difficulty moving, she also made her identity card, so that she does not feel marginalized.

Xue'er also asked Zhu Zhu for Yuan Qidong's identity card so that Yang Siyu and the others could be authorized to enter his room.

When everything was done, the four girls happily ran to the restaurant to have a big meal, regardless of their figures.

Not to mention how those girls ran around like crazy, Yuan Qidong was a blessing in disguise this time.

Before Yuan Qidong was kicked unconscious, he was at a critical juncture in his thinking. There are many clues buzzing in my ears and eyes like flies, but I can't see it, I can't catch it, and when I was jumping in a hurry, I was kicked by Du Xiaomei.

After he passed out, his consciousness seemed to enter an ethereal world, and inexplicable light came from a distance, mixed with the complex structures of those genes, but those complex structures changed from a string of boring symbols to three-dimensional entities, just like the building blocks of children.

These entities not only have a three-dimensional structure, but also a three-dimensional force field, which hovers and dances with each other under the action of the force field, sometimes aggregating, sometimes decomposing, and changing shape.

Mathematically, 1+1=2.

Physically, one force plus another is equal to the resultant force.

But chemically, one molecule, plus another, may be equal to one, two, three, or more molecules.

It seems that chemistry is more troublesome.

Yuan Qidong has been trying to think about how to express the interaction between proteins, proteins and all other substances involved in life activities in a more intuitive and understandable form. If this problem is solved, the problem of how to simulate life activities more concisely can be solved, and the progress of the choking system can be further accelerated.

Why choose protein for research, because protein is the primary substance of life activities and is indispensable.

There is a wide variety of proteins in living organisms. Some of them become the structural materials of biological organisms, some play a role in regulating physiological activities in the body, some catalyze biochemical reactions in the body, and some resist foreign bodies in the body.

The role of proteins is extremely powerful, as in the case of enzymes that catalyze biochemical reactions in the body. Most enzymes catalyze reactions millions of times faster without catalysis.

There is a compound called uracil nucleoside-6-carboxylic acid-5'-phosphate, and the carboxylic acid group in its molecule can be decomposed and carbon dioxide can be removed according to the structure. Under natural conditions, it is estimated that it will take 78 million years to decay by half, which means that it is stable. However, if it meets uracil-6-carboxylic acid-5'-phosphate decarboxylase, this process takes only 25 milliseconds, which can be said to be instantaneous.

Another example is a molecule of catalase, which can break down 40 million hydrogen peroxide per second. Another example is carbonic anhydrase, which is found in red blood cells, which catalyzes the mutual conversion of carbon dioxide and water with hydrogen ions and bicarbonate ions, which allows red blood cells to transport carbon dioxide from tissues to the lungs. One molecule of it can process 1 million carbon dioxide molecules per second.

We can figuratively think of each protein as a tool, with a specific function, some pliers, some wrenches, screwdrivers, scissors, and so on.

When we eat walnuts, if there is no walnut clip, we can only use other tools or bricks, or even frantically smash the walnuts directly on the ground, and the resulting pulp may be rotten and inedible, but with this clip, we can eat walnuts while watching TV, eat walnuts while drinking tea, and eat walnuts while chatting. The conditions for eating walnuts become very low.

Simple tools do this, while some proteins are equivalent to more complex tools, such as lathes, welding equipment, communication equipment, and so on.

Relying on these tools, it is possible to produce more complex devices such as radios, televisions, and automobiles in the human body, as well as to lay roads, build bridges, build factories, open mines, and even build cities, and also form a complete communication system, which is faster and more convenient than the Internet. Our human body is the equivalent of a world.

Of course, there are no workers to operate these tools, everything is done in a natural state. For example, when the wrench meets the bolt, the wrench and the bolt are attracted to each other and attached to each other due to the force of the chemical bond, and at the same time, due to the interaction of unbalanced forces between molecules, the wrench can start to pull the bolt until the bolt is tightened. After the bolt is tightened, the structure changes, the force of the chemical bond also changes, the wrench is no longer attracted, the two sides are separated, and the wrench begins to look for the next bolt that needs to be tightened.

This unbalanced force may be one-tenth or even less of the chemical bonding force, but the effect is very large, so powerful that it is beyond our imagination. For molecules with an unbalanced structure, such as the most common water molecule, due to the different density of the electron cloud, the two hydrogen-oxygen bonds form an angle, so that each molecule will have an unbalanced force acting on the other molecules, so that these molecules can attract each other. The result is what we see as the surface tension of the water.

If water has no surface tension, then even the smallest drop of water will drip due to gravity, and it will even be so small that our eyes can't tell it. But how big the water droplets we see are, it's about 17 trillion trillion water molecules tangled together because of this weak force.

In fact, the interaction of various macromolecules in living organisms also depends on this unbalanced molecular force. Due to the special structures of different organic macromolecules, this force becomes very prominent.

Because of the benefits of these tools, organisms continue to accumulate useful tools in the process of evolution. As long as the tools that are beneficial for survival are recorded on the chromosome, they become a piece of gene. Well, that's how we've accumulated more than 39,000 genes.

In fact, there are many organic macromolecules, which we humans do not have a blueprint in their genes and cannot be manufactured, but the human body needs them very much. For example, those vitamin molecules and so on, we can only supplement these organic molecules by eating vegetables and fruits.

However, some races have recorded this gene in their genes, and they can solve this problem by themselves without eating vegetables and fruits, such as Eskimos who live in cold regions for many years. They have been eating meat for many years, and some of them have never eaten vegetables and fruits in their lives, and they also live a very healthy life. If you do that, you may be hanging up in a few months.

Don't be convinced, that's the difference between having tools and not having them.

Since proteins are so important, what is the structure of proteins?

Proteins are essentially macromolecular peptides, such as insulin, which is a polypeptide composed of 51 amino acid groups. Most proteins are polypeptides made up of a few hundred amino acid groups. The type, number, and order of amino acid groups on a polypeptide chain are combined to form the primary structure of a protein.

The genes in all living organisms record the primary structural information of these proteins.
