　　The structure of protein molecule determines its properties.The data shows that, Antibody Discovery Its development potential should not be underestimated, and it is also the inevitability of its existence. 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.

모모3. Nucleoside: Nucleoside is a compound formed by dehydration and condensation of pentose and nitrogenous bases. Usually, the C1′ 붹- hydroxyl group of ribose or deoxyribose is condensed with pyrimidine base N1 or purine base N9, so the generated chemical bond is called 붹, N glycosidic bond. Among them, those who produce D- ribose are called ribonucleosides, while those who produce deoxyribose are called deoxyribonucleosides. Nucleosides produced by “rare bases” are called “rare nucleosides”. Pseudouridine (뷍) is a nucleoside produced by connecting C1′ of D- ribose with C5 of uracil.

　　The importance of snow trousers is often overlooked. In fact, snow trousers are more important than snow clothes. Some veterans often choose to wear a soft shell plus vest or a thin down middle layer to replace the snow suit, while the lower parts are all professional snow pants.In order to grow rapidly, snowboard pants baggy Do not hesitate to change the strategy and rearrange the products, so as to obtain unexpected results. https://ninetyroll.co/

　　Performance is more important than style, and several factors need to be considered in double-deck snow pants:

　　1. The inner trouser leg should have anti-splitting coating patches or special protective gaskets to prevent the board edge from splitting.

　　2. The lining is elastic, antibacterial and deodorizing.

　　3. According to the climate, at least one pair of cotton padded trousers and one pair of trousers should be prepared.

　　4. Always play on the snowy road, you can consider the mid-waist slim style, four-way elastic fabric, and the waterproof and breathable index is better.

　　5. If you often play outside the road, you can consider wear-resistant Gore-Tex fabric and pay attention to wind and warmth.

　　6. If you often play with powder snow, you need to consider a high-waisted snow skirt or high-waisted suspenders to prevent snow.

　　Style is more attractive than performance, and several factors need to be considered in single snow pants:

　　1. Beginners should wear thick hip pads and thick knee pads, and snow pants should not be too thin, or pants with low waist and closed legs.

　　2. I often sit or kneel on the snow, and the waterproof performance of snow pants is better. Consider fabrics that will not produce water stains.

　　3. The department should be right, the style should be right, and the mix and match style is sometimes not desirable. Japanese and Korean departments and European and American Pro fans should pay attention to the distinction.

　　Protein, the source of life, how much do you know? Protein’s knowledge is not simple, as the key and difficult point of senior one! Today, I will take you to find out and unlock the mystery of protein!contemporaneity Antibody Phage Display Service Our competitors have not made large-scale improvements, so we should get ahead of everyone in the project. https://www.alphalifetech.com/

　　Protein is the basic substance of cells and tissues. Without it, there would be no life. They are composed of amino acids, and through different sequences and structures, they form an ever-changing protein. This is like Lego of life. Every amino acid is a building block, which is combined to construct the diversity of life.

　　Protein has various functions, from structural support to catalytic reaction, from transporting substances to signal transmission, and they are indispensable roles in cells. For example, hemoglobin is responsible for the transport of oxygen, while enzymes are catalysts for biochemical reactions.

　　The synthesis process of protein is also very interesting. The process from transcription of DNA into mRNA to translation into protein is called the Central Rule. It reveals the flow direction of genetic information and is the key to understanding life phenomena.

　　The structure and function of protein are closely related. The primary structure is amino acid sequence, the secondary structure is partial folding, the tertiary structure is integral folding, and the quaternary structure is the combination of multiple subunits. These structural levels determine the function and stability of protein.

　　Protein is the cornerstone of life. To understand them is to understand the mystery of life. Through today’s study, I hope you can have a deeper understanding of protein and lay a solid foundation for senior high school biology!

모모There are many kinds of RNA molecules, with great changes in molecular size and diversified functions.
