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.

　　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.

　　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.
