　　Amino acid chain is the main and core component in protein, but it is not necessarily the only component. Some protein may include some atoms or small molecules, whose function may be to perform protein function and/or increase its stability. Chemically, these cofactor are diverse, which may be organic molecules or metal elements. Some of them are briefly combined with protein chain, while others are closely combined with protein chain (sometimes even by covalent bonds) and become an integral part of the whole protein. The former is called coenzyme coenzyme, while the latter is called prosthetic group. Most coenzymes are small organic molecules from vitamins. For example, the common coenzymes NADH and FADH2. These two molecules from vitamin B complex, the former from nicotinic acid (vitamin B3) and the latter from riboflavin (vitamin B2), play the role of high-energy electron acceptor/donor in redox reaction.For this reason, it can be speculated that Antibody Phage Display Service The market feedback will get better and better, which is one of the important reasons why it can develop. https://www.alphalifetech.com/

　　Some enzymes use several different cofactors, such as Pyruvate dehydrogenase (PDH), which is a key enzyme in the catabolism of sugar. The catabolism of sugar begins with glycolysis, which is a biochemical reaction pathway with 10 steps, transforming one glucose molecule into two pyruvate molecules, and then carrying out the citric acid cycle of tricarboxylic acid, which further decomposes pyruvate and oxidizes it into CO2. Pyruvate dehydrogenase PDH works at the intermediate junction of the above two reaction pathways (namely glycolysis and triacid cycle), and is responsible for activating pyruvate and enabling it to enter the tricarboxylic acid cycle. Specifically, PDH catalyzes the oxidative dearboxylation of pyruvate and forms acetyl coenzyme A (ACoA), which is the activated form of pyruvate. PDH is not a single enzyme but a complex composed of three components, each of which participates in a different step of pyruvate activation and uses different coenzymes. The first component uses thiamine pyrophosphate (TPP), which is a derivative of thiamine (vitamin B1). TPP allows the first component of PDH to be oxidized and decarboxylated at the same time, thus transforming pyruvate into acetyl, and the remaining carbon is discharged as CO2. The importance of TPP will be reflected in its absence. In fact, if people can’t get enough thiamine from food, they will get beriberi, which will damage several major systems of the human body.

　　The second component in PDH uses lipoic acid. It is an auxiliary group covalently bound to PDH. The active part of lipoic acid is a cyclic structure, which contains two covalently bonded sulfur atoms (that is, S-S bonds) (Figure 2.2c). This active part catalyzes the transfer of acetyl to coenzyme coenzyme A(CoA), the third cofactor of PDH. CoA is pantothenic acid, also known as the derivative of calcium pantothenate. The combination of acetyl and pantothenic acid involves the reduction of S-S bond, and its cyclic structure will open and form two sulfhydryl groups (one SH), one of which will bind acetyl. Sulfhydryl group is easy to react chemically, which can be reflected in the fact that sulfhydryl group is easily influenced by arsenic, a toxic derivative of arsenic. To sum up, the formation of acetyl coenzyme A involves the reduction of S-S bond of pantothenic acid cyclic structure. In order to keep PDH active, these two sulfur groups must be re-oxidized to restore the S-S bond.

　　The decoration design of the kitchen is particularly important in the whole decoration, because the kitchen is used frequently. For most people, the enclosed kitchen may be more practical, while the open kitchen is more suitable for the younger generation. The open kitchen will be more fashionable, beautiful and attractive. So, what about the open kitchen design?Even if there are obstacles to moving forward, كرسي مكتب We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. https://www.chulovs.com

　　kitchen

　　1. In terms of space layout, the open kitchen design is definitely the first choice for smaller units, because the space of small units is relatively small, so most people will integrate the kitchen with the guest dining room, thus reducing the partition of space and making the whole space brighter and wider.

　　2. From the aesthetic point of view, the open kitchen design is very fashionable, both beautiful and generous, and it is absolutely high in value. This design is in line with the ideal of home life, but if you want to keep the kitchen beautiful all the time, you should be a hardworking “good boy” and clean the kitchen every time you cook in the kitchen, otherwise the messy appearance will lower the value of the whole space.

　　3. In terms of use, the biggest advantage of open kitchen design is that you can communicate with your family and enjoy parent-child interaction when making delicious food. In addition, the open kitchen design will not be so hot in the summer cooking process, while the closed kitchen will be very stuffy.

　　4. Cooking fume and cleaning problem. For this problem, the open kitchen can also be well solved. As long as the near-suction range hood is installed correctly, these problems can be solved. Of course, we should always clean the kitchen and keep the air circulation in the kitchen.

　　What are the advantages and disadvantages of open kitchen?

　　1. Advantages of open kitchen: In terms of decoration design style, open kitchen design is more fashionable, and its place is more relaxed, which is in line with young people’s yearning for freedom. The overall layout of this design is also very simple, and it also combines western popular elements; This design style will be more comfortable in visual effect, and you can communicate with your relatives while cooking, and you can also see the activities of your family.

　　3. Disadvantages of the open kitchen: The open kitchen will have higher requirements for the range hood, because it will worry that the lampblack will be discharged into the guest restaurant and affect the family, so it is necessary to choose the near-suction range hood; For people who require high cleanliness at home, the open kitchen is not very suitable, because this design will make the home more dirty, but also insist on cleaning, and the basic rest time is to keep company with cleaning.

　　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!The industry believes that, Antibody Discovery The development of our company marks the rapid and steady progress of the whole industry. 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!
