Web1751.5. As seen in Tables 22.5, 22.6, and 22.7, the polyglycerol is highly esterified (at least 4 acids per glycerol, and probably naming 5). The excess in the iodine value suggests a mixture of triglycerol and tetraglycerol oligomers, which is very common in the oligomerization process of glycerol. WebGlycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel′s sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component.
