There are some differences between heparin and crude heparin. Many people confuse the two. Crude heparin sodium is also called crude heparin sodium. When extracting, the relevant extraction method or purity information cannot be ignored. So how does crude heparin form?
Crude heparin sodium is usually made by extracting sulfuric acid from pig intestinal mucosa. The sodium salts of glucosamine can be made into molecules through several steps such as the separation and purification of labor or heparin. Heparin and other new anticoagulants have certain antithrombotic or anticoagulant effect, and the molecular weight of crude heparin sodium is different. Depending on our specific method or procedure, the molecular weight will be different. Usually a linear chain of repeating units in six or eight sugars. Most molecular weights are between 30,000 and 30,000, with an average molecular weight of around 15,000. From the outside, of course, they are solid particles or powders of yellow, brown, near-gray, or similar colors.
Now we have a better understanding of how crude heparin sodium is formed. This component in crude heparin sodium does not mix easily with organic solvents such as ethanol or acetone, so it can be stored with these solvents during storage, but it mixes easily with water. So be sure to store in a cool dry ventilated place, do not touch the water.
