The enzyme alcohol dehydrogenase converts alcohol to acetaldehyde, a sympathomimetic toxin often blamed for the ‘hangover’ effect. Acetaldehyde is further metabolized by aldehyde dehydrogenase to acetic acid, and eventually to carbon dioxide and water. Excretion of small amounts of alcohol also ...
作为动词，"alcohol"的意思是使……含酒精或用酒精处理。例如，在一篇关于酿酒工艺的文章中，作者可能会写到："Wine is made by fermenting grapes with yeast, which converts the sugar in the grapes into alcohol."（葡萄酒是通过用酵母发酵葡萄制成的，酵母将葡萄中的糖转化为酒精。）作为形容词，"alcohol"...
acids (acetic acid, lactic acid, gluconic acid, etc) and dissolved sugar. Most of us know that alcohol does not freeze. (at least in our freezers). CO2, Sugar ,acids all combine with water and lower water's freezing point to around 28F But in our home freezer ...
they tend to develop toasty notes. Even in cooler climates, Chardonnay has little difficulty developing sugar. This promotes the potential for high alcohol levels. Low acidity levels can be a problem, however. These wines tend to be flabby or dull. In cases like this, the winemaker can add ...
This is easy to believe when you consider that fermentation happens naturally when the skin of a fruit is split open. The sugar in the fruit attracts natural yeast in the environment around it, which eats the sugar and converts it into alcohol. The earliest evidence of alcohol doesn’t begi...
1 Sugar essentially converts directly into alcohol, so an 11 per cent increase in the average sugar content of wine grapes implies a corresponding 11 per cent increase in the average alcohol content in wine. Questions arose as to whether the rising sugar content of grapes was indeed reflected ...
b. Undistilled alcohol:Undistilled alcohols are also called fermented drinks. Fermentation is the process by which bacteria or yeast chemically converts sugar into ethanol. Wine and beer are both fermented, undistilled alcoholic beverages. Wineries ferment grapes to make wine, and breweries ferment ...
Yeast ferments sugars and converts them into alcohol. It does so by converting the amino acids in sugars into ethanol. Congeners are a by-product of this reaction. The amount of congeners in a drink depends on the carbohydrate used, the original sugar, and the yeast strain that ferments ...
Ethanol (pure alcohol) mixes readily with water and various water solutions like sugar syrup, but it will not mix directly with sugar.
Are sugar alcohols good for you? Tooth Decay Unlike sugars, sugar alcohols do not promote tooth decay, since the bacteria in mouth do not readily convert them to acids[8]. Xylitol and, to a lesser extent, sorbitol may even have a protective effect on teeth[8,9,10]. ...
