When all three reactive groups are esterified with long chain organic fatty acids, a triglyceride is formed. Glycerol is technically a sugar alcohol. Glycerol can influence immune reactions in the body through histamines, increased antibody production and by enhancing immune cell activity and is therefore classified as an allergen. Glycerol’s ability to retain moisture and its emollient properties make it an attractive ingredient in many moisturizing formulations.

Adjuvant glycerol and/or dexamethasone to improve the outcomes of childhood bacterial meningitis: a prospective, randomized, double-blind, placebo-controlled trial. Glycerol is seen in biological systems as an intermediate in carbohydrate and lipid metabolism because surplus carbohydrate can be converted into long chain fatty acids and esterified with the three hydroxyl groups. We currently have no information for GLYCEROL Interactions. 2013 Nov-Dec;5(11-12):896-9. Its boiling point is 290°C but it also decomposes at that temperature.

Alfred Nobel, who later instituted the Nobel Prizes, discovered a method for the reliable stabilization, transport and handling of trinitroglycerin, which is the central explosive compound in dynamite. Arnall DA, Goforth HW. He obtained glycerol when the glycerol was washed out of a heated mixture of lead oxide and olive oil. View abstract. The presence of multiple hydroxyl groups and carbon atoms makes it an organic polyol compound with the IUPAC name of 1, 2, 3 – Propanetriol.

Suppositories of glycerol can act as laxatives since they can irritate anal mucosa. This also makes it useful as a humectant in cosmetics and food, retaining water and preventing the substance from drying out.

Glycerol is a common food and drink additive because it is nontoxic and has a sweet tasting flavor. This copyrighted material is provided by Natural Medicines Comprehensive Database Consumer Version. In addition, the molecule can be shown with a more accurate depiction of bond angles, without the explicit representation of the hydrogen atoms. Glycerol is easily soluble in water, due to the ability of the polyol groups to form hydrogen bonds with water molecules. The presence of multiple hydroxyl groups and carbon atoms makes it an organic polyol compound with the IUPAC name of 1, 2, 3 – Propanetriol. “Glycerol.”, Biologydictionary.net Editors. In food, the utility of glycerol arises from its ability to form inter-molecular hydrogen bonds, especially with water molecules.
