It is mainly used in polyvinyl chloride (PVC) as suspension polymerization dispersant and stabilizer. It can improve the average particle size, particle size distribution, particle morphology and internal structure of suspended polymer. In addition, HPMC can also be used as thickener, stabilizer, emulsifier, excipient, water retaining agent and film-forming agent in the production of petrochemical, coatings, building materials, paint remover, agricultural chemicals, ink, textile printing and dyeing, ceramics, papermaking, cosmetics and other products.
Glycine is one of the 20 members of amino acid series with the simplest structure, also known as aminoacetic acid. It is a non essential amino acid for human body. It has both acidic and basic functional groups in the molecule. It is a strong electrolyte in aqueous solution, has high solubility in strong polar solvent, and is insoluble in non-polar solvent. This product is mainly used in pharmaceutical industry, biochemical test and organic synthesis. For example, it is used as buffer, preparation of tissue culture medium, test of copper, gold and silver, and medically for the treatment of myasthenia gravis and progressive muscle atrophy, gastric acidosis, chronic enteritis, hyperprolinemia in children and other diseases.
Leucine is one of the twenty basic amino acids. It and isoleucine are isomers. In nutrition, leucine is an essential amino acid for human body. Leucine is the most common amino acid in proteins, and it is important for normal development of infants and children and nitrogen balance in adults. It is speculated that leucine may play an important role in maintaining muscle by balancing protein biochemistry and decomposition. The main food sources of leucine are: whole grains, milk, dairy products, eggs, pork, beef, chicken, beans and leafy vegetables.
Starch is white and light yellow powder. The grain is soaked in 0.3% sulphurous acid and then crushed, sieved, precipitated, dried and ground. Ordinary products contain a small amount of fat and protein, strong moisture absorption, up to 30%. Starch sugar industry uses starch to produce high maltose syrup, fructose syrup, maltodextrin, etc. Starch is used in modified starch industry, and its modified starch is widely used in papermaking, chemical industry and other industries. Starch is used in fermentation industry to produce monosodium glutamate, citric acid and many other products. Starch is also widely used in metallurgy, casting and other industries.
Valine is one of twenty protein amino acids. From a nutritional point of view, valine is also an essential amino acid. Its English name valine is named after valerian, and its Chinese name is also called valine. Its codons are guu, Gua, GUC and GUG. It is a nonpolar amino acid. In sickle cell disease, valine in hemoglobin replaces the hydrophilic amino acid glutamate: because valine is hydrophobic, hemoglobin cannot fold correctly. Valine is completely electrically neutral. When its side chain is also neutral, and the charge generated by its amino and carboxyl groups is just balanced, this molecule is called zwitterion. Food sources rich in valine include white cheese, fish, poultry, cattle, peanuts, sesame seeds and shore beans.It is used in medicine as one of the components of amino acid infusion, and can also be used as a nutritional supplement
