Application
1.Biological reagents, apis, and intramolecular sulfhydryl groups (-SH) can break the disulfide chain (-S-S) that binds the mucin peptide chains in mucus. Mucin becomes a peptide chain of small Chemicalbook molecules, reducing the viscosity of sputum; It can also break the DNA fiber in purulent sputum, so it can dissolve not only white phlegm but purulent sputum as well.
2.It is used in medicine to dissolve phlegm. Used in biochemical research, medicine as phlegm dissolving drugs and acetaminophen poisoning antidote.
3.Used in biochemical research, medicine as phlegm dissolving drugs and acetaminophen poisoning antidote.
4.Biochemical reagents, medicine, used as an expectorant, said sputum easy clean, easy to cough static. It breaks down thick sputum. The mechanism is that the sulfhydryl group in the molecular structure of the product can break the disulfide bond in the mucin polypeptide chain in the sputum, break the mucin, reduce the viscosity of the sputum, and make it easy to liquide and cough out. It is suitable for acute and chronic respiratory diseases in which the phlegm is thick and difficult to cough out, and a large amount of phlegm obstruction caused by suction due to difficult critical symptoms.
