WebApr 1, 2006 · The addition of 2 m glycerol to the deionized water lowered its pH to approximately 5.6. Similarly, the addition of 2 m sucrose to deionized water lowered its pH to about 5.8. Both glycerol and sucrose contain, per their labels, traces of acid, which would cause a slight pH reduction in unbuffered solutions. Glycerol is a precursor for synthesis of triacylglycerols and of phospholipids in the liver and adipose tissue. When the body uses stored fat as a source of energy, glycerol and fatty acids are released into the bloodstream. Glycerol is mainly metabolized in the liver. Glycerol injections can be used as a simple test for liver damage, as its rate of absorption by the liver is considered an accurate measure of liver he…
