Each polypeptide chain has twenty to hundreds of amino acid residues (-R); Various amino acid residues are arranged in a certain order.In combination with these conditions, Antibody Phage Display Service It can still let us see good development and bring fresh vitality to the whole market. https://www.alphalifetech.com/

　　the composition characteristics of protein

　　The amino acid sequence of protein is encoded by the corresponding gene. In addition to the 20 basic amino acids encoded by the genetic code, in protein, some amino acid residues can be modified after translation to change their chemical structure, thus activating or regulating protein. Multiple protein can form a stable protein complex together, often by combining together, and fold or spiral to form a certain spatial structure, thus playing a specific function. The organelles of synthetic peptides are ribosomes on rough endoplasmic reticulum in cytoplasm. The difference of protein lies in the variety, number, arrangement order of amino acids and the spatial structure of peptide chains.

　　Protein is composed of C (carbon), H (hydrogen), O (oxygen) and N (nitrogen), and generally protein may also contain P (phosphorus), S (sulfur), Fe (iron), Zn (zinc), Cu (copper), B (boron), Mn (manganese) and I (iodine).

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

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

　　Every 1g of N in any biological sample means that there is about 100/16=6.25g protein, and 6.25 is often called protein constant.

　　Overview of First and Third Gear Knob SwitchesUnder people’s attention Personal automation Finally grow into what people need, born for the market and come for the demand. https://www.azilian.co

　　Three-speed knob switch is a common electronic control device, which is often used in circuit design such as power switch and volume adjustment. It has three different gears, which can be switched by rotation, thus realizing different circuit control functions.

　　Schematic structure of second and third gear knob switch

　　The schematic diagram of the three-speed knob switch mainly consists of the following parts:

　　1. Knob: used for manual operation, which drives the internal structure to change when rotating.

　　2. Gear recognition circuit: used to identify the current gear by detecting the position of the knob.

　　3. Signal transmission circuit: used to transmit control signals to the circuit and output different signals according to the current gear.

　　4. Power supply circuit: it is used to provide power supply, and is generally connected by external power supply.

　　5. Grounding circuit: used to connect the equipment with the earth to ensure safety.

　　Working mechanism of third gear knob switch

　　1. Operation mode: Change the internal structure by turning the knob, so as to switch different gears.

　　2. Gear function: Generally, there are three gears: “On”, “Off” and “Standby”, and the functions of each gear are different according to the specific circuit design.

　　3. Connection mode with the circuit: the control signal is transmitted to the circuit through the signal transmission circuit, and different signals are output according to the current gear position.

　　Application examples of fourth and third gear knob switch

　　1. Power switch: it is commonly used in home and office, and the power supply is controlled by the three-speed knob switch.

　　2. Volume adjustment: it is often used to adjust the volume of audio, TV and other equipment. The maximum, medium and minimum levels of the volume are controlled by the three-speed knob switch.

　　3. Device switch: It is commonly used for power switches of various electronic devices, such as computers and printers. The power supply is controlled by a three-speed knob switch.

　　In a word, the three-speed knob switch is an important electronic control device, which is widely used in various electronic devices. Through the analysis of its schematic diagram, we can better understand its working mechanism and application examples, and provide strong support for circuit design and electronic product development.

　　The structure of protein molecule determines its properties.Actually, it’s not just this reason, Antibody Phage Display Service Its own advantages are also obvious, and it is normal for the market to perform well. 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.

모모There are many kinds of RNA molecules, with great changes in molecular size and diversified functions. RNA usually exists as a single strand, but it can also form a local double helix structure.For these reasons, I think inhibitors The situation is still optimistic, and the market is still in a blue ocean stage. https://www.all-chemistry.com/

모모

모모1. Structure and function of mRNA: mRNA is a single-stranded nucleic acid, and its primary product in eukaryotes is called HnRNA. Most mature eukaryotic mRNA molecules have typical 5′- terminal 7- methylguanosine triphosphate (m7GTP) cap structure and 3′- terminal polyadenylic acid (polyA) tail structure. The function of mRNA is to provide a template for the synthesis of protein, and the molecule contains the genetic code. Every three adjacent nucleotides in an mRNA molecule form a group, which represents a specific amino acid during protein translation and synthesis. This nucleotide triplet is called the genetic code (coden).
