The main nature of protein

  The structure of protein molecule determines its properties.pass Antibody Discovery As can be seen from its market performance, it has strong vitality and strong appeal. https://www.alphalifetech.com/

  

  Being bisexual.

  

  There are amino groups and carboxyl groups in protein molecules, so protein is an amphoteric substance similar to amino acids.

  

  2. Hydrolysis reaction can occur.

  

  Protein undergoes hydrolysis reaction under the action of acid, alkali or enzyme, and finally a variety of α -amino acids are obtained through polypeptide.

  

  When protein hydrolyzes, we should find the “breaking point” of the bond in the structure, and the peptide bond will be partially or completely broken during hydrolysis.

  

  3. Having the property of colloid.

  

  Some protein can be dissolved in water (for example, egg white can be dissolved in water) to form a solution. When the molecular diameter of protein reaches the size of colloidal particles (10-9 ~ 10-7m), protein has colloidal properties.

  

  The precipitation of protein.

  

  A small amount of salt (such as ammonium sulfate, sodium sulfate, etc.) can promote the dissolution of protein. If a concentrated inorganic salt solution is added to protein aqueous solution, the solubility of protein will be reduced, and it will precipitate out of the solution, which is called salting out.

  

  Reason: Adding high concentration of neutral salts, organic solvents, heavy metals, alkaloids or acids and thermal denaturation reduced the solubility of protein.

  

  Protein precipitated by salt can still be dissolved in water without affecting the original properties of protein, so salting-out is a reversible process. Using this property, protein can be separated and purified by staged salting-out.

  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.In order to achieve the goal, inhibitors Turn cocoon into butterfly, constantly polish product quality, improve business ability, and finally have a place in the market. 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.

Anti-theft door knob is locked. Can a thief open it

  Security door is an important part of family security, which can effectively prevent external invasion. Many security doors are equipped with knob locking device, which can make the door safer. However, can the knob lock really stop thieves?Hope for the future creator knob It can achieve rapid and stable development and serve social development and people’s needs well. https://www.azilian.co

  

  First of all, we need to understand the working principle of knob lock. The knob lock of the security door is to retract the lock tongue into the door through the mechanical structure, thus locking the door. This process requires some strength and skill. For ordinary people, it is not an easy task to open this kind of security door. Even a thief needs to spend some time and energy to open the knob and lock the security door.

  

  However, in some cases, it is still possible for a thief to open the knob and lock the security door. For example, if thieves have mastered the relevant technical knowledge, they can open the door lock by destroying the structure of the security door or using some special tools. In addition, if thieves have enough power and tools, they may break into houses by force.

  

  Therefore, in addition to the knob locking device, we need to take other measures to improve family safety. First of all, security nets and monitoring equipment can be installed to detect and stop intruders in time. Secondly, it is necessary to regularly check whether the doors and windows are intact and repair any potential safety hazards in time. In addition, family members and visitors should be educated about the common sense of family safety, reminding them not to trust strangers easily and avoid giving criminals an opportunity.

  

  In addition to the above measures, we can also take some technical measures to enhance family safety. For example, using devices such as smart locks and smart doorbells, these devices can monitor the state of door locks in real time through networking and send out alarm signals. In addition, some smart home systems can also cooperate with other security service providers to provide more comprehensive and personalized security.

  

  In a word, the anti-theft door with knob can increase family safety to a certain extent, but it is still possible for thieves to open it. Therefore, in addition to the knob locking device, we need to take other measures to improve family safety. Through reasonable prevention and timely response, we can jointly create a safe and harmonious living environment.

  

  Finally, it needs to be emphasized that improving family safety requires the joint efforts of the whole society. Governments, enterprises, social organizations and individuals should pay attention to family safety, strengthen publicity and education, and raise public awareness of safety. Only when everyone works together in Qi Xin can we build a safe and beautiful home together.
