Comprehensive Overview

The Chemistry of EtOH

To fully appreciate the role of EtOH in medicine, it is essential to understand its basic chemistry. Ethyl alcohol has the chemical formula C2H5OH. It consists of two carbon atoms, six hydrogen atoms, and one oxygen atom. The presence of the hydroxyl group (-OH) is what classifies it as an alcohol. This simple structure gives EtOH its unique properties, including its ability to dissolve both polar and nonpolar substances, making it an excellent solvent.

The production of EtOH typically involves the fermentation of sugars by yeast or through chemical synthesis. Fermentation is a natural process where microorganisms convert sugars into alcohol and carbon dioxide. This method is used to produce alcoholic beverages. In contrast, synthetic EtOH is produced from ethylene, a byproduct of petroleum refining. Both forms of EtOH have their applications in medicine, depending on the specific requirements.

Historical Significance
