Chapter 17 Synthesized!

It was related to his mother's physical health, even though he knew that his active behavior would cause his daughter-in-law to be unhappy, Ye An was still busy helping Ye Ling to inquire if the laboratory of the Capital Pharmaceutical Factory could be used.

In recent years, in response to the country's call for "vigorously developing science and technology", basically a well-known factory has started 'research and development', raw meat factories have developed ham sausages, trying to rely on ham sausages to go abroad and earn foreign exchange for the country...... As a leading pharmaceutical company in China, Capital Pharmaceutical Factory naturally has its own 'R&D room'.

However, the pharmaceutical factory is different from other factories, take the raw meat factory that makes ham sausages as an example, as long as people control the amount of salt and meat added, refine the production process a little, keep up with the production equipment, stir and grind the meat of the ham sausage, and make the taste better, naturally someone will pay, and the same is true for canned fruit, but how easy is the research and development of the pharmaceutical factory?

The formula of each drug is made by countless scientists with painstaking efforts, how can it be done casually?

The leaders of the Capital Pharmaceutical Factory thought about building the 'R&D room' vigorously, but the reality was that the talents could not keep up, and the panacea for curing diseases could not be made, but a bunch of poisonous things were made, and the mice used for testing drugs died in batches...... The R&D room was closed half a year after its establishment, and the equipment was covered with a white cloth, leaving only the equipment for testing the ingredients to be used occasionally.

Ye An has worked in the Capital Pharmaceutical Factory for many years, and has a good relationship with the director of the Capital Pharmaceutical Factory, plus Ye Ling ventilated the nose of the grandson of the factory director's family, when he went to the factory director to borrow the laboratory, the factory director just told him not to break the equipment in the laboratory, and then wrote a note of approval.

It's just that you have to buy the raw materials for the experiment.

Ye Ling, in line with the idea of 'reluctant children can't trap wolves', paid out of her own pocket to ask Ye He to go to the capital pharmaceutical factory's purchase relationship to help her buy D-glucose and black acetic acid bacteria, which are 'maybe' useful for mass production of vitamin C, and then took the time when she was not in class to do fermentation experiments in the R&D room of the Capital Pharmaceutical Factory.

According to the part of the method on vitamin C synthesis mentioned in the "Little Pandan Pill", Ye Ling strictly controlled the experimental conditions and temperature, and advanced step by step.

First of all, D-glucose is converted into the intermediate product D-sorbitol under the synergistic catalysis of hydrogen, and D-sorbitol produces L-sorbitate under the fermentation of black acetic acid bacteria, and then L-sorbose is fermented for the second time, and mixed strains of black acetic acid bacteria are added to form 2-KGA, and finally undergo internal lipidation and enolation reactions to synthesize stable vitamin C.

It was only a short sentence to write, but just the conversion of D-glucose into D-sorbitol, Ye Ling groped for two days to get a glimpse of the door.

At the appointed time, it was Qin Chunsheng, the director of the Capital Pharmaceutical Factory, and his wife Li Yuehong who came with the little fat dun Zhuangzhuang.

Li Yuehong saw Ye Ling as if she was seeing her daughter, and grabbed Ye Ling's hand and thanked her, "Xiao Ye! Thank you so much! Since I used the loofah ash you said to drink water, my strong nose has passed, but occasionally when I wake up in the morning, it is still a little blocked, and there is a little more snot, but it looks much better than before. No one would have imagined that a simple loofah would have such a good nose effect when burned to ashes! "
