"Dr. Wu, please don''t say it - you don''t understand it." the patient said with a smile.

    He heard the previous conversation and took it out to tease Wu Mian.

    It''s also boring. He also wants to chat with this adorable hospital, so he ran over to ask.

    "This is really a good question, let me think about it." Wu Mian stroked the rabbit''s ear and thought for a few seconds. "But what I said is because the books we have read are different. You understand every word I say, but together you don''t know what it means. Don''t say you, even ordinary doctors don''t understand the terms of Rheumatology and immunology."

    "Hmm, I understand." the patient has nothing to do. He thinks Wu Mian''s big yellow rabbit ears are very kind. It''s more interesting to find him to spend time than chasing a play. He doesn''t worry and listens with a smile.

    "It''s interesting about the source of vitamins. Beriberi spread among Dutch soldiers and sailors in 1886.

    Therefore, scientist Christian Ackerman chose to experiment with chickens to find possible pathogenic bacteria.

    Ekman found that chicken feed once changed from brown rice to refined rice, and the symptoms of beriberi in chicks appeared when * * rice and disappeared when feeding brown rice.

    But he only found that rice bran can treat beriberi, but he didn''t know the specific ingredients.

    It was not until 1910 that the Dutch chemist Casimir funk extracted and purified an amine crystal from rice bran and thought it was an ingredient for the treatment of beriberi. Because the crystal contained amines, the substance was named vitamin. "

    "This is an experiment of good luck in the history of science. Therefore, luck is very important in scientific research. That''s the principle.

    Let me give you a simple example. You must know.

    Viagra was developed to treat heart disease. Unexpectedly, it became Pfizer''s fist drug, bringing billions of profits every year. "

    "But I always think that if scientists'' research depends on life, it''s too unreliable." the patient was not worried about listening to vitamins, but chatted with Wu Mian.

    "Science and technology trees are different from games. Some scientists have studied for a lifetime and finally found that they have gone the wrong way since the day they entered the industry. The only achievement in this life is to tell future generations that this road is impassable. Therefore, luck is very important!"

    “……”

    "It''s all tears. It''s tragic, really." Wu Mian said seriously. "What''s more, there are many wrong achievements in the history of science. Let''s talk about vitamins later."

    "At first, vitamins refer to amines needed for life; now, we think that vitamins refer to substances in addition to fat, protein and carbohydrates, which are trace in the body but are very important for normal physiological functions.

    The human body''s own synthetic amount often can not meet the needs, but once it is lacking, it will lead to idiopathic diseases. "

    "In 1915, it was found that the" vitamin "named by Casimir funk essentially contained two substances, fat soluble and water-soluble.

    These two substances were named vitamin A and vitamin B respectively. At that time, it was decided that if new vitamins were found in the future, they would be listed according to the alphabet A to Z. "

    "Like the first emperor and the second Qin Dynasty?" the patient asked.

    Wu Mian was slightly stunned, then stroked a rabbit''s ear and said with a smile, "don''t say it. Your description is particularly appropriate."

    "Right," the patient laughed.

    "According to the plan, it should be like Mendeleev''s periodic table of elements. The vitamins are arranged neatly, waiting for everyone to find out.

    At first, it was also very smooth. Vitamin C, vitamin D and vitamin E all appeared obediently according to this law. However, there was a problem at F. "

    "Scientists quickly identified two of them and called them" vitamin F "and" vitamin g ". However, because these two substances are separated from vitamin B, many people also call them" vitamin B1 "and" vitamin B2. "

    "However, vitamin F was quickly picked up and finally abandoned."

    "Is it because scientists don''t want to believe that vitamins are different from the periodic table?"

    "Yes, no one wants to do research all his life, and nothing can be left." Wu Mian said. "How good the periodic table of elements is. Comrade Mendeleev has long calculated it. As long as others find it, they can leave a strong mark in the history of science."

    "Tut Tut, if you say so, I think scientists are also very cute."

    "A particularly miserable group of people have no money for scientific research and have to flatter the capitalists. You see the Mercedes Benz life starring Shen Teng."

    "Yes."

    "In order to race cars, they both have to sing and jump steel pipes for big money. Scientists... Almost the same. All kinds of fraud, just to get some money for scientific research."

    "I''ll go..."

    "But when many scientists see that they have money, they forget what their first dream was. Now it''s called not forgetting their first heart. That''s what it means." Wu Mian said with a smile, "so, as long as they are people."

    "Well, when you say so, how can I feel that the halo of scientists is gone."

    "There was no aura. Is it difficult for a rich man to be a man without money? It''s the same for a scientist, except for the genius with the aura of the protagonist."

    "Are you?"

    "I don''t count. It sounds like my resume is scary, but it''s just compared with ordinary people. If it''s compared with genius, it''s not enough." Wu Mian narrowed his eyes and said.

    The patient was stunned. The general resume of this cute inpatient has been spread in the shelter hospital recently. The more it is spread, the more outrageous it is, but it is often true.

    That''s it, isn''t it a genius?!

    "Musk, do you know?"

    "I know. I''ve been paying attention to what man-machine interface I''m working on."

    "Fart is useless. It''s a gimmick, including rocket recycling. But young people like the star sea. It''s the star sea! So it doesn''t matter what scum musk is. He''s on the right road and picks up the halo again."

    Wu Mian made the patient faint and said from vitamin to musk that scum.

    However, Wu Mian''s thinking was very clear. He withdrew the topic and said after chatting with the patients for more than ten minutes, "because the naming history of vitamins is so chaotic, the invisible International Federation of Nutritional Sciences finally took over the matter and determined the current vitamin naming principle in 1978."

    "The principle is very long, so I won''t say much. It''s mainly easy to remember. For example, it is stipulated that" niacin "is the general name of pyridine-3-carboxylic acid compounds and their derivatives with nicotinamide like biological activity."

    "Brother! Good news!" Chu Zhixi trotted over and excitedly touched the rabbit ears on Wu Mian''s head.

    "What''s the matter? I''m so happy."

    "President Zhang said that if there were no accidents, the Qiaokou martial arts shelter hospital would be closed tomorrow!"

    This,

    That''s really good news.
