Artemisinin?
Su He seemed to remember that it was recorded in later generations.
The newly produced artemisinin pills are not digested in the body because of low solubility, and are directly excreted from the body.
Drug solubility refers to the solubility of a drug in a solution, which has an important impact on the absorption, distribution, metabolism, and excretion of drugs.
The higher the solubility of a drug, the faster its absorption, the faster the drug effect, the higher the drug concentration, and the better the therapeutic effect on the disease.
As for artemisinin pills, it seems that they are too hard due to the stamping process.
In addition, there are some ingredient issues that cause artemisinin pills to have low solubility in the human body and cannot be digested in a timely manner.
The pill simply leaves the stomach and is expelled from the body.
When the human body takes medicine, it is generally digested, dissolved, and absorbed by the body in the stomach.
Once it enters the intestine, it is more difficult to absorb.
But there was no dispute between the two of them.
In fact, in the ancient times of Rabbit Country, there was no such application.
The vast majority of antibiotic fermentations are anaerobic cultures, which require continuous introduction of a small amount of bacterial air and low-power stirring throughout the process.
Obviously, Professor Yan is also very satisfied with me.
Why not use a saw to cut the board and nail it together with nails.
Siding Group is all about taking the high-quality route, so it needs supporting facilities.
One is that domestic machines are relatively backward, and some auxiliary materials that need to be used in the production process are still relatively backward in China.
That would hurt Xiaoya and cause some conflicts.
Professor Wang and Professor Zheng hadn't started arguing yet. Professor Wang came over triumphantly and said to Su He: "He will follow you first. Your latest project is the research on penicillin pills. His courses are usually self-study, it's nothing If he understands, I will ask you. If you were here, none of the other professors would be able to explain it to him."
[Currently used, it is the most complete and best-used app for listening to books. It integrates 4 major speech synthesis engines, over 100 kinds of sounds, and supports offline reading.
Su He also said that Professor Wang's team's method of preparing penicillin antibiotics was still relatively advanced.
Moreover, he also embarrassed himself once.
Seeing Professor Wang, who was still trying to persuade, he and Professor Zheng ended their argument.
If there is no organic nitrogen source, use less corn steep liquor, soybean cake powder, gluten powder, protein powder, yeast powder, fish meal, etc. Ammonium sulfate, urea, ammonia, sodium nitrate, and ammonium nitrate are commonly used organic nitrogen sources.
I know that the industrial production of antibiotics includes fermentation and extraction. The process flow is as follows: strain preservation, spore preparation, seed preparation, fermentation, extraction and refining.
I looked at Professor Yan and asked, "By the way, Professor Yan. Did you just hear that this artemisinin pill has very bad effects?"
I think so.
It’s really informative.
Bah, I have refused, what a brother-in-law.
Su He called the other party's name.
Then if I am taken away by Mr. Wang next door, where will I show my face?
So Professor Wang smiled, for fear of scaring Su He, and said in a serious voice: "Well, Da Su. His learning ability is indeed very weak. But, that person's energy is not limited, it is possible to learn everything .For example, your person who specializes in pharmaceuticals will learn from you. If he can master it in the shortest time, then he will do a few more experiments and write a few papers. There will be problems even after graduating from a master's degree... …”
Also used in the treatment of endocarditis caused by viridans streptococci and Enterococci (in combination with aminoglycosides), tetanus caused by Clostridium, gas gangrene, diphtheria, and epilepsy. inflammation, rat bite cold, syphilis, leptospirosis, Visen (Vi) angina, actinomycosis, etc.
It may be better than special people, but after meeting the professor in that field, there is nothing to say.
Shu Zheng had nothing to say, and the initial result was still settled.
A crude box is also very difficult to make.
I still had time to ask Sheng Wenqiao what was wrong, Professor Wang saw me and waved.
In the future, environmental protection will also be a small branch of chemistry.
The two of them were talking before they even left the small building.
I only memorized the last few chapters of organic chemistry, and I basically had no problems.
My own big cotton-padded jacket, even if it is Bai Xinmian, can make it easy for Su He to get it.
That was not the earliest application of penicillin in the Rabbit Country.
If the learning progress is too slow, it means that his learning ability is not enough, so he should specialize in one subject as soon as possible.
Later, when I was making handmade air conditioners, I actually made one for myself.
"You go make a phone call."
How many years are they apart from each other, but they have no close relationship with each other as brothers?
When I compare the boxes I made, it’s like a buyer’s show versus a seller’s show.
"Don't be too familiar with us. Let me tell you, he can't learn from you about the environment. People in the country all look at the economy. Rarely do they sacrifice the environment as a means to earn economic benefits. In the future, wait for the environment Even if it is destroyed, you still have to spend money to manage it every year..."
Professor Yan also knew that, and immediately said to Su He: "He is also concerned about that? You, the Taoist priest, know something about that. Later, the research on artemisinin showed some effects. So artemisinin pills were produced, but Is it effective? It seems that it is digested and excreted directly."
Su He, that bad boy, doesn't have a very bad understanding of communications and electronics.
"Shu Zheng is here? How were those days?"
No matter which branch it is, at the end of the course, you have to learn both organic and analytical physics, and those branches of chemistry.
The materials are in place. If you buy them from somewhere, one is expensive, and the other is bad quality.
That's something that can be done.
It's more difficult to get past this box.
I must have come from a previous life, and I would definitely feel that there is a difference between a high-quality product and a four-dollar product with free shipping.
I'm still thinking, is it like men, who only have a few comfortable days every month?
But speaking of it, Su He really wanted to work with the chemical and electronic automation departments to research thermal chain equipment.
Each scientist is likely to study not just one, but may be proficient in two fields.
But if no one provokes them, they will immediately form an alliance and face each other unanimously.
Mainly because Sheng Wenqiao also refused.
That involves shipping out my stuff and accelerating the expansion of those stores on the flag.
Su He frowned: "Well, maybe it has nothing to do with the condensation degree of the pills, right? It has nothing to do with the stamping data of the pharmaceutical factory. Otherwise..."
Professor Wang found that Shu Zheng's self-study ability was very bad.
Commonly used penicillin drugs include penicillin G, penicillin V, amoxicillin, ampicillin, etc.
Is this carpentry so bad?
Just like Tingxiang, if it wants to develop, it needs the products from my farm to be delivered in place.
Commonly used carbon sources for seeds and fermentation media include: glucose, starch, sucrose, oil, and inorganic acid, which mainly provide energy for bacterial growth and metabolism and provide carbon elements for the synthesis of bacterial cells and target products.
Professor Wang still knows that knowledge.
Shu Zheng was always talking eloquently, and it was obvious that I was just improvising, but I really learned it step by step.
Professor Yan originally cared about it, but when he heard Shu Zheng's words, he frowned. After thinking about it, he felt that what Shu Zheng said might not make sense.
There is a shortage of medical care and many drugs in the country. New production methods for penicillin drugs are developed every year, but there is no method for extracting penicillin drugs. This is still very unhelpful for the current situation where there is a shortage of medical treatment and many drugs.
It seems that the eldest son has taken care of his sister, and he will definitely be his brother-in-law in the future.
Penicillin is a very important monster, including a few drugs that are penicillins.
He brought a lot of books, several for each subject.
However, the specific methods are still lagging behind.
Those two people, if anyone provokes us, they will pinch themselves.
After some questioning, Su He found out that everything he said was very wrong.
What's more, a bad teacher also wants to accept a bad student.
Those two people might really want to accept Su He as a student.
Today, these professors also ask themselves some questions to observe his learning progress.
That point is not very different from the international situation.
Professor Wang is basically satisfied. I still want to make further inquiries about Shu Zheng's level of reading.
That's absolutely allowed.
Professor Yan’s idea is quite right. I am also a professor of chemistry, but I only specialize in the environment.
I asked about some analytical chemistry content.
The old mustard stew is not to store the mustard greens in jars and let them mold naturally. Wait until a few years ago to get the old mustard stew every year.
For example, analysis methods, some instruments used, etc.
Pretreatment of fermentation broth, especially the addition of flocculant to precipitate protein, filtration to remove mycelium, extraction of fermentation filtrate commonly used solvent extraction method, ion exchange resin method, precipitation method, adsorption method, etc. to purify and concentrate, and then crystallize and moisten to obtain pure product.
For example, organic chemistry, inorganic chemistry, analytical chemistry, and environmental chemistry.
Moreover, it is memorized by rote, but it is really a matter of learning.
Shu Zheng nodded and agreed to come up.
At the undergraduate level, what Xiaojia studied was not a chemistry subject. It might not be called applied chemistry, but it might also be basic chemistry.
Su He didn't say much, chatted with the doorman Old Huang for a few words, and then walked inside.
Professor Yan stopped, and Professor Wang and Professor Zheng ended up fighting again.
Another professor came over. Shu Zheng remembered that the professor's surname was Yan, and everyone in the family called me Professor Yan.
It's only been a few days, and Shu Zheng hasn't learned that much yet?
"What's wrong with me? Why are I so crazy?" Wang
asked the professor.
Professor Yan stepped in and immediately convinced Professor Wang and Professor Zheng to agree.
Su He shook his head. Of course he didn't express his guess. He always discussed with Professor Wang whether women would be the same as men and not have such needs, right?
"There's a long way to go." It was obvious that I got to know him first, so Su He also gave me some gifts.
The two immediately stopped arguing, and then said to Professor Yan: "Old Yan, he looks like a dog, and you thought he was an honest man. Did you think that he wanted to steal a house?"
That was what he thought later, but at this time, Sheng Wenqiao felt that he had suffered a loss.
It is only when you reach the prelude that you need to specialize and learn in a more profound direction.
I fumbled around and got a motor, but it was difficult to make a large electric fan.
Su He was not surprised by this resentful expression: "Wen Qiao, who is he?"
"That organic chemistry..."
That equipment only involves electronic automation, but also involves chemistry.
Sheng Wenqiao is also such a generous person.
Like Chen Xuan, Sheng Wenqiao is a master's student who has not yet graduated, and I am unemployed.
I remember that there are actually few ways to extract penicillin.
Su He answered all the questions I asked, and he answered them correctly.
I smiled and cared.
Such a bad idea must be specialized in chemistry, which is really a pity.
But at the master's level, it will be subdivided.
Shu Zheng also tried to figure out what was wrong with Sheng Wenqiao.
During the fermentation process, a carbon source and nitrogen source are generally added, such as glucose and ammonium sulfate. The pH value is degeneratively adjusted by feeding ammonia. Very few antibiotics are added in the early stages of fermentation, which is very unhelpful in improving yield.
When Professor Wang was questioning me just now, Professor Yan was at the side and retreated after hearing this.
But I don’t have any knowledge of physics, and I don’t have any knowledge of electronics. It’s just that I’m very old.
We work for the country, but it is also an honor, right?
Professor Yan was also very eloquent, and I myself was a very eloquent person, so I immediately stopped.
Su He naturally nodded: "Professor, you read it. In the past few days, you read a book on organic chemistry, which also involved some analytical chemistry..."
The heating aspect is still very important.
I just watched it, and I also learned it and learned it through.
I am a science and engineering girl, but I have problems with hands-on work.
Su He noticed Shu Zhengwei's strange attitude and knew what was wrong with the other party.
As for retreating to the small building, Sheng Wenqiao chased him from the front.
And without hot chain equipment, some products cannot be mobilized across regions.
Ri Nian said that it is a widely used drug.
In addition, organic salts, trace elements and antifoaming agents must be added to the culture medium. Some antibiotics must also add common precursors. For example, the precursor of penicillin is phenylacetic acid, and the precursor of small lactone antibiotics is propionate. .
