Composition and characteristics of protein

  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).So, recombinant proteins On the contrary, there is still a lot of room to play. 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.

How to choose the right ski pants What are your suggestions

  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.Hope for the future ninetyroll snowpants It can achieve rapid and stable development and serve social development and people’s needs well. 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!

Material Metabolism and Regulation

  Focus on glycolysis, aerobic oxidation of sugar, pentose phosphate bypass, gluconeogenesis, synthesis of ketone bodies, cholesterol and phospholipids, respiratory chain, oxidative phosphorylation, special amino acid metabolites, one carbon unit metabolism, purine and pyrimidine nucleotide synthesis raw materials and catabolites, and substance metabolism.according to inhibitors Industry veterans said that its development will still be in a good situation. https://www.all-chemistry.com/

  

  The chapter on sugar metabolism is the focus of the exam, so we should master it comprehensively. The chemical reaction formula of sugar metabolism is complicated, and the focus of the annual examination is basically on the reaction site, key enzymes and regulation, energy production and the relationship between important substances. Glycolysis, gluconeogenesis and aerobic oxidation of sugar are all contents that must be familiar with. The synthesis of ketone bodies and cholesterol in lipid metabolism, pay attention to the difference between them. Ketones are synthesized in the liver and utilized outside the liver, while fats are synthesized in the liver and stored outside the liver. Fat synthesis, ketone body synthesis and cholesterol synthesis are the raw materials of acetyl-CoA synthesis. Synthesis and decomposition of fatty acid, the main material of fatty acid synthesis is acetyl CoA; Under the condition of sufficient oxygen supply, fatty acid is decomposed into CO2 and water in the body, releasing a lot of energy, which is the main form of fatty acid catabolism in the body. Phospholipid synthesis. Differentiation of several blood lipids.

  

  Composition of respiratory chain and influencing factors of oxidative phosphorylation. Urea synthesis-ornithine cycle. One carbon unit’s metabolism is often tested, but it is easy to remember as long as you grasp the core content. It comes from one carbon unit-Sisegan, and is transported by one carbon unit-tetrahydrofolate. One carbon unit plays an important role in nucleic acid biosynthesis as a raw material for purine and pyrimidine synthesis, connecting amino acids and nucleotides. Comparison of nucleotide synthesis and decomposition between purine and pyrimidine. The changes in this year’s syllabus are: the deamination of amino acids (oxidative deamination, transamination and combined deamination) is changed to the general metabolism of amino acids (degradation of protein in vivo, oxidative deamination, transamination and combined deamination), which should be reviewed.

The function of protein

  Protein is the “building material” of organisms and cells, such as protein in muscles, and human hair and nails are all made of protein.Not only does it perform well in data, Antibody Discovery In the market share, it is also gradually expanding, so that more people can benefit. https://www.alphalifetech.com/

  

  Catalytic function:

  

  The chemical essence of most enzymes in organisms is protein. In our daily life, we also use enzyme-added washing powder, which can effectively remove stains.

  

  Immune function:

  

  In our present environment, there are bacteria and viruses everywhere, and our body will not get sick every three days with an immune system, and immune proteins, such as antibodies, play a key role in this.

  

  Transport function:

  

  Protein with transport function can be divided into two categories, one is familiar to us-hemoglobin in red blood cells, which is used to transport oxygen; The other is the carrier protein on biofilm, which is used to transport amino acids, glucose and other substances.

  

  Adjustment function:

  

  Some protein can transmit information and regulate the life activities of the body. Such as insulin, which regulates glucose metabolism.
