　　In the vast universe of science, organic chemistry is like a bright star, leading us to explore the mystery of life. As a subject of studying carbon compounds, organic chemistry, with its unique charm, closely links all fields of natural science and reveals the material basis of life phenomena for us. Organic chemistry, an important branch of chemistry, is a subject that studies the source, structure, properties, separation, preparation, application and related theories of organic matter. “Organic matter” here refers to compounds containing carbon elements, such as alcohols, aldehydes, carboxylic acids, etc. It is worth noting that although organic matter mainly comes from organisms, with the development of science and technology, people have been able to synthesize many artificial organic compounds with biological activity, such as drugs, dyes, plastics and so on.

　　

　　The main research contents of organic chemistry include: synthetic chemistry of organic matter; Metal organic chemistry and elemental organic chemistry; Physical and theoretical organic chemistry; Stereochemistry; Bioorganic chemistry; Natural product chemistry; Chemistry of organic materials.

　　

　　The importance of organic chemistry:

　　

　　1. Basis of life: From the origin of life to the growth and development of organisms, carbon always plays a vital role. Through the study of organic chemistry, we know the structure and function of biological macromolecules such as protein, nucleic acid, sugar and lipid, which are the material basis of life.

　　

　　2. Key in the field of medicine: Many drugs and bioactive substances are organic compounds, such as antibiotics, antiviral drugs and hormones. By studying the structure and function of these substances, scientists are constantly discovering new treatments to protect human health.

　　

　　3. The core of industrial production: Organic chemistry plays an important role in industrial production. For example, in the process of petroleum refining, heavy hydrocarbons in petroleum can be converted into light hydrocarbons by the action of catalysts; In the process of plastic synthesis, organic chemical reactions provide a steady stream of power for the plastic industry. Although organic chemistry has made remarkable achievements in many fields, it still faces many challenges.

　　

　　First of all, in environmental protection, how to realize green synthesis and reduce the discharge of harmful waste is an urgent problem for organic chemists.

　　

　　Secondly, in the field of medicine, how to improve the selectivity of drug molecules and reduce side effects is also a difficult problem to be solved urgently. Faced with these challenges, organic chemists are constantly exploring new reaction mechanisms, catalysts and synthetic methods. I believe that in the near future, organic chemistry will bring us more surprises and inject new vitality into the development of human society. Organic chemistry, as a discipline to study the molecular cornerstone of life, plays an important role in natural science. Let’s walk into this wonderful world hand in hand, grow in exploration, break through in innovation, and jointly write a bright future of organic chemistry.

　　Separation and purification of protein;It is strictly required by such a standard, inhibitors Only with today’s development scale, can we have the proud momentum to crush our competitors. https://www.all-chemistry.com/

　　

　　1. Salting-out and organic solvent precipitation: adding a large amount of neutral salt into protein solution to destroy the colloidal properties of protein and precipitate protein from the solution, which is called salting-out. Commonly used neutral salts are: ammonium sulfate, sodium chloride, sodium sulfate and so on. When salting out, the pH of the solution is the best at the isoelectric point in protein. Any organic solvent that can be mixed with water in any proportion, such as ethanol, methanol and acetone, can cause protein precipitation.

　　

　　2. Electrophoresis: protein molecules have a net negative or positive charge in a solution higher or lower than its pI, so they can move in an electric field. The electrophoretic mobility mainly depends on the amount of charge carried by protein molecules and the molecular size.

　　

　　3. Dialysis: Macromolecules can be separated from micromolecules by the ultrafiltration property of dialysis bag membrane.

　　

　　4. Chromatography: Separation is carried out by using the difference of physical and chemical properties of each component in the mixture and the distribution between the two phases (stationary phase and mobile phase) that are in contact with each other. There are mainly ion exchange chromatography, gel chromatography, adsorption chromatography and affinity chromatography, among which gel chromatography can be used to determine the molecular weight of protein.

　　

　　5. Ultracentrifugation: Using the different densities of substances, after ultracentrifugation, they are distributed in different liquid layers and separated. Ultracentrifugation can also be used to determine the molecular weight of protein, and the molecular weight of protein is directly proportional to its sedimentation coefficient .

　　Protein is composed of C (carbon), H (hydrogen), O (oxygen) and N (nitrogen). Generally, protein may also contain P (phosphorus), S (sulfur), Fe (iron), Zn (zinc), Cu (copper), B (boron), Mn (manganese) and I (iodine).Even so, recombinant proteins We must also adhere to the quality of the industry and create unique products for the company. https://www.alphalifetech.com/

　　

　　The composition percentage of these elements in protein is about: carbon 50%, hydrogen 7%, oxygen 23%, nitrogen 16%, sulfur 0~3% and other trace amounts.

　　

　　(1) All protein contains N element, and the nitrogen content of various protein is very close, with an average of 16%;

　　

　　(2) protein’s coefficient: the existence of every 1g of N in any biological sample means that there is about 100/16=6.25g of protein, and 6.25 is often called protein’s constant.

　　

　　(3) protein is a biopolymer based on amino acids. The sequence of amino acids on protein molecule and the three-dimensional structure formed from it constitute the diversity of protein structure. Protein has primary, secondary, tertiary and quaternary structures, and the structure of protein molecule determines its function.

　　Ski pants are by no means ordinary pants, but your right-hand man for adventure in the snow, allowing you to travel freely in the world of white clothes. Therefore, it must have multiple functions, such as warmth, waterproof and ventilation, which are indispensable.For this reason, it can be speculated that baggy snowpants The market feedback will get better and better, which is one of the important reasons why it can develop. https://ninetyroll.co/

　　

　　When choosing ski pants, I pay special attention to the material. The importance of waterproof fabric is self-evident. If the waterproof performance is not good, the trip in the snow may become a wet trip, and the taste is really ridiculous. Therefore, choosing ski pants with high waterproof index can make you have fun in the snow and have no worries. Thermal performance is also crucial. When skiing, the body loses heat quickly.

　　

　　If the ski pants are not warm enough, it will easily make people cold. Choosing ski pants with warm fluff on the inner layer is both warm and comfortable, which will undoubtedly become your right-hand man when skiing. In addition, air permeability can not be ignored. Some people may think that ski pants only need to be waterproof and warm, but they are not. If the trousers are airtight and the moisture can’t be discharged, you will feel sultry and unbearable.

　　

　　Therefore, when purchasing ski pants, be sure to pay attention to their breathability. Finally, comfort and design can not be ignored. Ski pants should be elastic enough to move freely when skiing. At the same time, pockets, zippers, etc. should also be designed reasonably to facilitate the storage of items. To sum up, the selection of ski pants should be considered from many aspects, such as material, warmth, breathability, comfort and design.

　　

　　Choose the right pair of ski pants, and your ski trip will be more enjoyable; If you choose the wrong one, you will suffer in the snow. Therefore, everyone must be careful when buying ski pants!

모모1. Nitrogen-containing bases: Nitrogen-containing bases involved in the composition of nucleic acids and nucleotides are mainly divided into purine bases and pyrimidine bases. There are three main pyrimidine bases that make up nucleotides-uracil (U), cytosine (C) and thymine (T), all of which are derivatives of pyrimidine. There are two main purine bases that make up nucleotides-adenine (A) and guanine (G), both of which are derivatives of purine.

모모

모모2. Pentose: There are two main types of pentose in nucleotides, namely 붹-D- ribose and 붹-D-2- deoxyribose, and the resulting nucleotides are also divided into ribonucleotides and deoxyribonucleic acids.

모모

모모3. Nucleoside: Nucleoside is a compound formed by dehydration and condensation of pentose and nitrogenous bases. Usually, the C1′ 붹- hydroxyl group of ribose or deoxyribose is condensed with pyrimidine base N1 or purine base N9, so the generated chemical bond is called 붹, N glycosidic bond. Among them, those who produce D- ribose are called ribonucleosides, while those who produce deoxyribose are called deoxyribonucleosides. Nucleosides produced by “rare bases” are called “rare nucleosides”. Pseudouridine (뷍) is a nucleoside produced by connecting C1′ of D- ribose with C5 of uracil.
