Tyrosine is an important nutritionally essential amino acid that plays an important role in the metabolism, growth and development of humans and animals, and is widely used in food, feed, medicine and chemical industries. It is often used as a nutritional supplement for patients with phenylketonuria, and as a raw material for the preparation of pharmaceutical and chemical products such as polypeptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, and p-hydroxystyrene. As more high-value-added L-tyrosine derivatives such as danshensu, resveratrol, and hydroxytyrosol are found in organisms, L-tyrosine is increasingly developing in the direction of platform compounds. Tyrosine is one of the 22 kinds of amino acids used by cells to synthesize proteins. It can be used to synthesize proteins in cells. Its codons are UAC and UAU. It is a non-essential amino acid that contains polar side groups and can be synthesized by the human body. The word "tyrosine" comes from the Greek tyros, meaning cheese. It was first discovered in the casein of cheese by the German chemist Justus von Liebig in the early 19th century. When it is used as a functional group or a side group, it is called tyrosyl. Function In addition to being a proteinogenic amino acid, tyrosine has a special role in signal transduction in proteins by means of a phenolic function, which functions as a receptor for phosphate groups transferred by protein kinases (so-called tyrosine kinase receptors). organ, while phosphorylation of hydroxyl groups alters the activity of the target protein. Tyrosine also plays an important role in photosynthesis. In chloroplasts (photosystem II), it is used as an electron donor in the reduction reaction of oxidized chlorophyll, allowing it to deprotonate the phenolic OH-group, and finally in Photosystem II is reduced by four core manganese clusters. Dietary Sources Tyrosine can be synthesized from phenylalanine in the body and can be found in many high-protein foods such as chicken, turkey, fish, milk, yogurt, cheese, cottage cheese, peanuts, almonds, pumpkin seeds, sesame, soybeans, lima beans , found in avocados and bananas.
White powder, apparent density:0.35-0.90g/ml, melting point: 622�°C, easily dissolving in water; water solution is alkaline (PH value of 1% solution is 9.7); can hydrolyze into phosphate in water, has good ability in complexing metal ions; can be used to soften water; has some surfactant properties. 1.In detergents The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg2+ and Ca2+), detergents are deactivated. Being a highly charged chelating agent, TPP5- binds to dictations tightly and prevents them from interfering with the sulfonate detergent. 2.Food Applications STPP is a preservative for seafood, meats, poultry, and animal feeds. It is common in food production as E number E451. In foods, STPP is used as an emulsifier and to retain moisture. Many governments regulate the quantities allowed in foods, as it can substantially increase the sale weight of seafood in particular. The United States Food and Drug Administration lists STPP as "generally recognized as safe.". 3.Other Uses Other uses (hundreds of thousands of tons/years) include "ceramics, leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze.
Fatty alcohol polyoxyethylene ether (AEO), also known as polyoxyethylene fatty alcohol ether. It is the fastest developing and largest dosage of nonionic surfactants. This type of surfactant is an ether formed by the condensation of polyethylene glycol (PEG) and fatty alcohol, which is represented by the following general formula: RO (CH2 H2O) NH, where n is the degree of polymerization, and there are different varieties due to different degrees of polymerization of polyethylene glycol and types of fatty alcohol.

Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.
Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
Product name: 2D measuring instrument Detailed product parameter description: Product model: SRN1515 Instrument features The Z axis adopts a new design of cross rails and counterweights. The lens is lifted and lowered with balanced force to ensure accuracy. The continuous zoom lens can be continuously zoomed from 20X to 120X. The LED cold light source (upper and lower light sources) avoids secondary deformation of the workpiece. Easy-to-use image measurement software. Gapless friction transmission, small-range fine-tuning and fast movement are possible. The optical image measuring instrument not only uses high-definition CCD imaging, combined with multi-pole zoom objective lenses, but also comes with easy-to-use image measurement software. It has point, line, circle, two-point distance, angle measurement functions and coordinate translation functions. The measurement data can be exported to EXCEL, WORD or the geometric figures of the measured elements can be exported to DXF. The automatic edge-finding function of the software further enhances the measurement accuracy and reduces human errors.
