If you have ever seen a person who has had too much to drink, you know that alcohol is a drug that has widespread effects on the body, and the effects vary from person to person. People who drink might be the "life of the party" or they might become sad and droopy. Their speech may slur and they may have trouble walking. It all depends on the amount of alcohol consumed, a person's history with alcohol and a person's personality.
Even though you have seen the physical and behavioral changes, you might wonder exactly how alcohol works on the body to produce those effects. What is alcohol? How does the body process it? How does the chemistry of alcohol work on the chemistry of the brain? In this article, we will examine all of the ways in which alcohol affects the human body.
What is Alcohol?
In order to understand alcohol's effects on the body, it is helpful to understand the nature of alcohol as a chemical, so let's take a look...
Here are several facts:
Alcohol is a clear liquid at room temperature.
Alcohol is less dense and evaporates at a lower temperature than water (this property allows it to be distilled -- by heating a water and alcohol mixture, the alcohol evaporates first).
Alcohol dissolves easily in water.
Alcohol is flammable (so flammable that it can be used as a fuel).
Alcohol can be made by four different methods:
Fermentation of fruit or grain mixtures
Distillation of fermented fruit or grain mixtures (Spirits such as whiskey, rum, vodka and gin are distilled.)
Chemical modification of fossil fuels such as oil, natural gas or coal (industrial alcohol)
Chemical combination of hydrogen with carbon monoxide (methanol or wood alcohol)
Ethyl AlcoholThe alcohol found in alcoholic beverages is ethyl alcohol (ethanol). The molecular structure of ethanol looks like this:
H
H3 C - C - O - H
H
In this structure, C is carbon, H is hydrogen, O is oxygen and the hyphens are the chemical bonds between the atoms. For purposes of clarity, the bonds between.
