What is the function of guaiacol?

Guaiacol is a monomethoxybenzene that consists of phenol with a methoxy substituent at the ortho position. It has a role as an expectorant, a disinfectant, a plant metabolite and an EC 1.1. 1.25 (shikimate dehydrogenase) inhibitor. It derives from a catechol.

Does guaiacol dissolve in water?

One gram of guaiacol dissolves in 60-70 ml of water or 1 g of glycerol. It is miscible with alcohol, chloroform, ether, oils, glacial acetic acid, and slightly soluble in petrolium ether.

Where is guaiacol found?

Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. Guaiacol has been found in the urine of patients with neuroblastoma and pheochromocytoma.

What does guaiacol smell like?

Guaiacol and its derivatives are commonly found in nature and are known for their characteristic smoky, clove-like and vanilla-like smells.

How is guaiacol formed?

The HDO of guaiacol (GUA, 2-methoxyphenol), a typical model compound for bio-oils formed by pyrolysis of lignocellulosic biomass, was tested with novel hydroprocessing catalysts derived from supported transition metal phosphides: Ni2P/SiO2, Fe2P/SiO2, MoP/SiO2, Co2P/SiO2, and WP/SiO2 (177).

What is guaiacol solution?

Guaiacol (/ˈɡwaɪəkɒl/) is a naturally-occurring organic compound with the formula C6H4(OH)(OCH3). Although it is biosynthesized by a variety of organisms, this aromatic oil is usually derived from guaiacum or wood creosote.

Is guaiacol an alcohol?

Moreover, such an understanding can contribute to the development of stock solution drug formulations. Indeed, guaiacol is one of the active compounds in a pharmaceutically active anti-cough oral solution, Pulmo Bailley®, in a mixture with water and a short polyol alcohol (glycerol).

Is guaiacol a substrate or product?

Enzyme assay Guaiacol was used as the target phenolic compound because it is a widely known substrate used for assaying peroxidase activity in the extract from different sources.

Is guaiacol a substrate?

Guaiacol was used as the target phenolic compound because it is a widely known substrate used for assaying peroxidase activity in the extract from different sources.

What is guaiacol in whiskey?

“The taste of whisky is primarily linked to so-called amphipathic molecules, which are made up of hydrophobic and hydrophilic parts. One such molecule is guaiacol, a substance that develops when the grain is dried over peat smoke when making malt whisky, providing the smoky flavour to the whisky,” Karlsson explains.

What is the role of guaiacol in the reaction catalyzed by turnip peroxidase?

In the reaction, guaiacol will donate hydrogens and thereby become oxidized. It has a brown color in its oxidized form; you will be able to measure the amount of oxidized guaiacol produced by determining the intensity of the color in the spectrophotometer.
