Descrição

Descrição geral

Glycerol is a simple polyol compound, which is obtained as a byproduct of soap and biodiesel industries.

Glycerol is odourless, colorless, viscous in nature, and exists as a sweet tasting liquid. It can be derived naturally as well as from petrochemical feedstock. Glycerol has a wide variety of applications, and is one of the most valuable and versatile chemical substances in nature. It can be used as an emollient, solvent, sweetening agent, in pharmaceutical formulations, cosmetics, foodstuffs and toiletries. It is very stable and can be easily stored under normal temperature; also it is non-irritating and has no adverse impact to the environment.

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food.

Aplicação

Glycerol has been used as

• a supplement during cell culture of Mycobacterium tuberculosis and Mycobacterium avium.
• a fuel during designing enzymatic biofuel cell.
• a liquid composite matrix with 4-HCCA and 3-amino­quinoline for analysis of neutral and acidic glycans.
• a matrix for fast atom bombardment MS.
• may be employed as liquid matrix for the quantification studies by MALDI (Matrix-assisted laser desorption/ionization mass spectrometry) analysis.

Glycerol may be used as a reference standard in the determination of glycerol in samples of beer using gas liquid chromatography (GLC).

O glicerol é usado no preparo da amostra e na formação de gel para eletroforese em gel de poliacrilamida. O glicerol (5%-10%) aumenta a densidade de uma amostra, de modo que a amostra forme uma camada no fundo do poço de amostra de um gel. O glicerol também é usado para preparar géis gradientes e como estabilizante proteico e componente do tampão de armazenamento.

Ações bioquímicas/fisiológicas

Glycerol is hygroscopic in nature and is soluble in water owing to its three hydrophilic alcoholic hydroxyl groups. It can form both inter- and intramolecular hydrogen bonds, making it a very flexible molecule. The physiologic effect of glycerine is due to cell-mediated immunity, increased IgG production and increased histamine release.
