Classification of amino acids, several special amino acids, molecular structure and physical and chemical properties of protein, composition of nucleic acid, double helix structure of DNA, basic concept of enzyme, Michaelis equation, coenzyme composition.Therefore, this is the choice inhibitors The reason, there is no denying its positive impact. https://www.all-chemistry.com/

　　Memorize 20 kinds of amino acids and try to remember English abbreviations and codes as much as possible, because exams often appear directly with codes. Protein’s molecular structure often examines the manifestations of various levels of structure and their bonds. The physical and chemical properties of protein and the purification of protein usually use the physical and chemical properties of protein to purify protein without destroying the structure of protein. Pay attention to the identification of amino acids and physical and chemical properties of protein. The basic unit of nucleic acid is nucleotide, which is composed of multiple nucleotides, and the connecting bond between nucleotides is 3′, 5′- phosphodiester bond. DNA double helix structure, in which two bases exist in strict accordance with A = T (two hydrogen bonds) and G triple C (three hydrogen bonds), and the characteristics of various RNA.

　　In addition, we should pay attention to some commonly used concepts in nucleic acid problem solving. The first thing that enzymes should pay attention to is some basic concepts, such as ribozyme, deoxyribozyme, enzyme activity center, isozyme, isomerase and so on. The key point of the Metric Equation test is V=Vmax[S” target=_blank>/Km+[S” target=_blank>, which explains the equation of the relationship between the concentration of enzymatic reaction and the reaction speed. In the exam, candidates are sometimes asked to do simple calculations according to this equation before they can answer. The difference of several inhibitors.

　　According to the characteristics of allosteric enzymes, it should be noted that allosteric regulation can cause conformational changes of enzymes. It is important to pay special attention here that configuration refers to the basic structural composition of substances, and conformation refers to the spatial change of substances. Allosteric regulation can cause the conformational change of enzymes, but not the conformational change of enzymes.

　　Protein is a substance with a certain spatial structure, which is formed by the zigzag folding of polypeptide chains composed of amino acids in the form of dehydration and condensation. However, natural protein molecules are not random loose polypeptide chains. Each natural protein has its own unique spatial structure or three-dimensional structure, which is usually called the conformation of protein, that is, the structure of protein. The sequence of amino acids in protein molecule and the three-dimensional structure formed from it constitute the diversity of protein structure.As we all know, recombinant proteins The emergence of the market is worthy of many people’s attention, which has aroused the waves of the whole market. https://www.alphalifetech.com/

　　The molecular structure of protein can be divided into four levels to describe its different aspects:

　　Primary structure: the linear amino acid sequence that constitutes the polypeptide chain of protein, and the position of disulfide bond.

　　Secondary structure: In the local area of protein molecule, the polypeptide chain is coiled and folded along a certain direction.

　　Tertiary structure: The three-dimensional structure of a protein molecule formed by the arrangement of multiple secondary structural elements in three-dimensional space.

　　Quaternary structure: used to describe protein complex molecules with biological functions formed by the interaction between different polypeptide chains (subunits).

　　In addition to these structural levels, protein can be transformed in several similar structures to exercise its biological functions. For functional structural changes, these tertiary or quaternary structures are usually described by chemical conformations, and the corresponding structural transformations are called conformational changes.

　　Design layout

　　The conference room is a quiet place, and it is the area where senior executives in the enterprise meet. This place cannot be excessively luxurious, but the layout must be reasonable. For example, the location of the display equipment products in the conference room is just right, so as to look comfortable and not tired. There is also the location where Zhu camera is installed, the location of Bluetooth speaker and so on.

　　Tone collocation

　　The tone of the meeting room is very important. Generally, the decorative tone of most meeting rooms is warm, which will make the mood more peaceful and create a harmonious atmosphere. The meeting room is taboo to use white, and the common colors are black, because these two reflective colors are strong, giving people an uncomfortable feeling.

　　Table and chair layout

　　Of course, the layout of tables and chairs in the meeting room is also a kind of knowledge. If we use a reasonable layout, the meeting room will look more atmospheric, solemn and classy. However, if the planning is unreasonable, the meeting room will become very crowded and chaotic, which will make the overall design effect poor.

Therefore, it is better to behave in a proper way in office decoration. After all, as a formal conversation occasion, the conference room is still solemn and can reflect the respect for consumers. In fact, as long as we grasp the details, we need to make our own reasonable arrangements according to the purpose of the office.

　　2. Sound control

　　As a formal conversation occasion, the two partners must have a quiet interactive dialogue environment, so when decorating the conference room, we must consider the sound insulation effect to prevent the sound outside the conference room from disturbing the ongoing discussion. This situation is not so pleasant for them, and of course, we must also consider the sound absorption, which can prevent the words from echoing indoors and not affect people’s mood.

　　3. Lighting design

　　When you are in office decoration, it will be better to choose a cold light source. In this case, a long meeting will not cause the indoor temperature to drop, and it will always protect your body in the future. Because there will be projection needs in the design of conference rooms, we should pay attention to coordinating the placement of projectors and lamps, so that the whole will be more coordinated.
