　　What to wear under ski pants?With the upsurge of industry development, cargo snow pants The expressive force in the market has also been very good, bringing many brand-new high-quality experiences to users. https://ninetyroll.co/

　　1. Ski socks

　　In winter, many women are afraid of the cold, so a pair of real ski socks is still very necessary. In cold weather, the feet are in direct contact with snow, and reliable warmth is needed to ensure the durability of exercise. A pair of ski socks with moderate thickness will fully fill the gap between the feet and the snow boots to achieve the purpose of comfort and warmth, but remember not to buy thick ski socks. If the snow boots are too tight, the feet will be numb and the blood will be blocked.

　　2, warm and sweat-wicking clothes

　　A truly warm and sweat-wicking ski suit is necessary. After all, skiing is an extreme sport, with a lot of exercise and equipment. All needs are based on lightness, thinness and warmth. Forget the ordinary jersey and long pants. If the budget is limited, you can also have ultra-thin thermal underwear. Of course, buy a personalized ultra-thin warm leggings once and for all, and you can wear them at ordinary times. There is no need to go to the ski shop to spend more money. Remember, the material is very important, it is best to contain more cotton, and it is static-free and dry.

　　3. Grab cashmere pants

　　Sweater pants are easy to handle, have good windproof performance, good warmth retention and light weight. Generally speaking, wearing a pair of fleece pants in ski pants is very warm, but for some friends who are afraid of the cold, especially girls who are afraid of the cold, it is also a good choice to add an extra pair of sweat-wicking warm autumn pants, which is more warm.

　　Points to pay attention to when choosing snow pants:In the long run, grey baggy snow pants The value will be higher and higher, and there will be a great leap in essence. https://ninetyroll.co/

　　1. Don’t just look at the fabric, but also cooperate with the lining, cutting technology and ergonomic design to play the role of the fabric.

　　2. there are many grades of core-tex, but the fabric of the highest grade is not necessarily suitable for all scenes.

　　3. Details will determine the comfort, such as the adjustment mode of the belt, the position of the breathable zipper and the position of the pocket. Different designs should be selected according to different scenes.

　　Conventional tailoring and slim tailoring have different application scenarios and different fabrics, so you should choose the tailoring method according to your own needs.

　　Separation and purification of protein;Even if there are obstacles to moving forward, Chemical Custom synthesis 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.all-chemistry.com/

　　1. Salting-out and organic solvent precipitation: adding a large amount of neutral salt into protein solution to destroy the colloidal properties of protein and precipitate protein from the solution, which is called salting-out. Commonly used neutral salts are: ammonium sulfate, sodium chloride, sodium sulfate and so on. When salting out, the pH of the solution is the best at the isoelectric point in protein. Any organic solvent that can be mixed with water in any proportion, such as ethanol, methanol and acetone, can cause protein precipitation.

　　2. Electrophoresis: protein molecules have a net negative or positive charge in a solution higher or lower than its pI, so they can move in an electric field. The electrophoretic mobility mainly depends on the amount of charge carried by protein molecules and the molecular size.

　　3. Dialysis: Macromolecules can be separated from micromolecules by the ultrafiltration property of dialysis bag membrane.

　　4. Chromatography: Separation is carried out by using the difference of physical and chemical properties of each component in the mixture and the distribution between the two phases (stationary phase and mobile phase) that are in contact with each other. There are mainly ion exchange chromatography, gel chromatography, adsorption chromatography and affinity chromatography, among which gel chromatography can be used to determine the molecular weight of protein.

　　5. Ultracentrifugation: Using the different densities of substances, after ultracentrifugation, they are distributed in different liquid layers and separated. Ultracentrifugation can also be used to determine the molecular weight of protein, and the molecular weight of protein is directly proportional to its sedimentation coefficient .

　　Protein is composed of C (carbon), H (hydrogen), O (oxygen) and N (nitrogen). Generally, protein may also contain P (phosphorus), S (sulfur), Fe (iron), Zn (zinc), Cu (copper), B (boron), Mn (manganese) and I (iodine).Not only does it perform well in data, Antibody Discovery In the market share, it is also gradually expanding, so that more people can benefit. https://www.alphalifetech.com/

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

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

　　(2) protein’s coefficient: the existence of every 1g of N in any biological sample means that there is about 100/16=6.25g of protein, and 6.25 is often called protein’s constant.

　　(3) protein is a biopolymer based on amino acids. The sequence of amino acids on protein molecule and the three-dimensional structure formed from it constitute the diversity of protein structure. Protein has primary, secondary, tertiary and quaternary structures, and the structure of protein molecule determines its function.

　　The chapter on sugar metabolism is the focus of the exam, so we should master it comprehensively. The chemical reaction formula of sugar metabolism is complicated, and the focus of the annual examination is basically on the reaction site, key enzymes and regulation, energy production and the relationship between important substances. Glycolysis, gluconeogenesis and aerobic oxidation of sugar are all contents that must be familiar with. The synthesis of ketone bodies and cholesterol in lipid metabolism, pay attention to the difference between them. Ketones are synthesized in the liver and utilized outside the liver, while fats are synthesized in the liver and stored outside the liver. Fat synthesis, ketone body synthesis and cholesterol synthesis are the raw materials of acetyl-CoA synthesis. Synthesis and decomposition of fatty acid, the main material of fatty acid synthesis is acetyl CoA; Under the condition of sufficient oxygen supply, fatty acid is decomposed into CO2 and water in the body, releasing a lot of energy, which is the main form of fatty acid catabolism in the body. Phospholipid synthesis. Differentiation of several blood lipids.
