Introduction
In 1779, Carl W. Scheele, a Swedish chemist, discovered a new transparent, syrupy liquid by heating olive oil and litharge . This new sweet-tasting compound was named Glycerol – from the Greek word glykys, which means sweet. Glycerol was found to possess a wide variety of uses in the manufacture of numerous domestic, industrial and pharmaceutical products. In recent times, …show more content…
Since glycerol has three –OH groups, three fatty acids must react with one glycerol molecule to make three ester functional groups and form triesters of glycerol or triglyceride. During this process three molecules of water are eliminated. The three fatty acids may or may not be identical.
Triglycerides are a type of lipid, or fat. They can be found in your blood. When we eat, our body converts calories it does not use right away into triglycerides, which our body later stores in our fat cells. Between meals, hormones release triglycerides to provide us with energy.
Glycerol is taken by mouth for weight loss, improving exercise performance, helping the body replace water lost during diarrhea and vomiting, as well as reducing pressure inside the eye in people with glaucoma . Athletes also use glycerol to keep from becoming dehydrated.
Healthcare providers sometimes give glycerol intravenously to reduce pressure inside the brain in various conditions including stroke, meningitis, central nervous system (CNS) trauma, CNS tumors etc; for reducing brain volume for neurosurgical procedures; and for treating fainting on standing due to poor blood flow to the
