Phenolic Aldehyde
Phenolic aldehydes are derivatives of phenol. Phenolic aldehydes can be found in wines and cognacs. Examples : * Hydroxybenzaldehydes * Protocatechuic aldehyde * Vanillin and isovanillin Isovanillin is a phenolic aldehyde, an organic compound and isomer of vanillin. It is a selective inhibitor of aldehyde oxidase. It is not a substrate of that enzyme, and is metabolized by aldehyde dehydrogenase into isovanillic acid, which cou ... * 2,3,4-trihydroxybenzaldehyde can be isolated from '' Antigonon leptopus''.Health-Beneficial Phenolic Aldehyde in Antigonon leptopus Tea.

Phenol
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water ...

Wine
Wine is an alcoholic drink typically made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide, releasing heat in the process. Different varieties of grapes and strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the wine production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes involve fermentation of other crops including rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry. Wine has been produced for thousands of years. The earliest evidence of wine is from the Caucasus reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognac
Cognac ( , also , ) is a variety of brandy named after the commune of Cognac, France. It is produced in the surrounding wine-growing region in the departments of Charente and Charente-Maritime. Cognac production falls under French appellation d'origine contrôlée (AOC) designation, with production methods and naming required to meet certain legal requirements. Among the specified grapes, Ugni blanc, known locally as Saint-Émilion, is most widely used. The brandy must be twice distilled in copper pot stills and aged at least two years in French oak barrels from Limousin or Tronçais. Cognac matures in the same way as whiskies and wines barrel-age, and most cognacs spend considerably longer "on the wood" than the minimum legal requirement. Production process Cognac is a type of brandy, and after the distillation and during the aging process, is also called '' eau de vie''. It is produced by twice distilling grapes produced in any of the designated growing regions. Grap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroxybenzaldehyde
Hydroxybenzaldehydes are phenolic aldehydes. The term may refer to: * Salicylaldehyde Salicylic aldehyde (2-hydroxybenzaldehyde) is the organic compound with the formula (C7 H6 O2) C6H4CHO-2-OH. Along with 3-hydroxybenzaldehyde and 4-hydroxybenzaldehyde, it is one of the three isomers of hydroxybenzaldehyde. This colorless oily ...

Protocatechuic Aldehyde
Protocatechuic aldehyde is a phenolic aldehyde, a compound released from cork stoppers into wine. This molecule can be used as a precursor in the vanillin synthesis by biotransformation by cell cultures of ''Capsicum frutescens'', a type of Chili pepper. It is also found in the mushroom '' Phellinus linteus''. Pharmacological effects Protocatechuic aldehyde regulates G protein-coupled estrogen receptor-1 (GPER-1) and exhibits protective effects in endothelial dysfunction and atherosclerosis.

Vanillin
Vanillin is an organic compound with the molecular formula . It is a phenolic aldehyde. Its functional groups include aldehyde, hydroxyl, and ether. It is the primary component of the extract of the vanilla bean. Synthetic vanillin is now used more often than natural vanilla extract as a flavoring in foods, beverages, and pharmaceuticals. Vanillin and ethylvanillin are used by the food industry; ethylvanillin is more expensive, but has a stronger note. It differs from vanillin by having an ethoxy group (−O−CH2CH3) instead of a methoxy group (−O−CH3). Natural vanilla extract is a mixture of several hundred different compounds in addition to vanillin. Artificial vanilla flavoring is often a solution of pure vanillin, usually of synthetic origin. Because of the scarcity and expense of natural vanilla extract, synthetic preparation of its predominant component has long been of interest. The first commercial synthesis of vanillin began with the more readily availa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isovanillin
Isovanillin is a phenolic aldehyde, an organic compound and isomer of vanillin. It is a selective inhibitor of aldehyde oxidase. It is not a substrate of that enzyme, and is metabolized by aldehyde dehydrogenase into isovanillic acid, which could make it a candidate drug for use in alcohol aversion therapy. Isovanillin can be used as a precursor in the chemical total synthesis of morphine. The proposed metabolism of isovanillin (and vanillin) in rat has been described in literature, and is part of the WikiPathways machine readable pathway collection. See also * Vanillin * 2-Hydroxy-5-methoxybenzaldehyde * ortho-Vanillin * 2-Hydroxy-4-methoxybenzaldehyde 2-Hydroxy-4-methoxybenzaldehyde is a chemical compound and an isomer of vanillin. Urolithin M7, one of the urolithins, has also been synthesized from 2-hydroxy-4-methoxybenzaldehyde using the inverse electron-demand Diels–Alder reaction. See ...

Antigonon Leptopus
''Antigonon leptopus'' is a species of perennial vine in the buckwheat family commonly known as coral vine or queen's wreath. This clambering vine is characterized by showy, usually pink flowers that can bloom throughout the year and large, heart-shaped leaves. ''A. leptopus'' is native to the Pacific and Atlantic coastal plains of Mexico, but also occurs as a roadside weed from Mexico south to Central America. It is widely introduced and invasive throughout tropical regions of the world, including in the south and eastern United States, the West Indies, South America, and the Old World tropics of Asia and Africa. This species is utilized for its edible tubers and seeds, but also for its horticultural properties as an ornamental vine in warmer parts of the world. Description ''Antigonon leptopus'' is a fast-growing climbing vine that holds on via tendrils, and is able to reach over 7 metres in length. It has cordate (heart-shaped), sometimes triangular leaves 25 to 75 mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
