Zinc chemical element, computer illustration.

Molecular model of acetic acid (ethanoic acid), C2H4O2 (structure CH3COOH), with carbon (black), oxygen (red), and hydrogen (blue). Acetic acid, one of the simplest carboxylic acids, is a colorless liquid that gives vinegar its sour taste and pungent smell.

Molecular model of formaldehyde, one of the congener compounds (along with ethanol) produced in alcohol fermentation. Congeners contribute to the flavor and color of alcoholic beverages and are believed to increase hangover symptoms.

Molecular model of isoamyl alcohol (also called isobutyl carbinol), one of the congener compounds (along with ethanol) produced in alcohol fermentation. Congeners contribute to the flavor and color of alcoholic beverages and are believed to increase hangover symptoms.

Molecular model of methanol (also called carbinol or methyl alcohol), one of the congener compounds (along with ethanol) produced in alcohol fermentation. Congeners contribute to the flavor and color of alcoholic beverages and are believed to increase hangover symptoms.

Molecular models of congener compounds (top to bottom): formaldehyde, methanol, acetaldehyde, isoamyl alcohol, and ethyl acetate. Congeners (along with ethanol) are produced in alcohol fermentation. They contribute to the flavor and color of alcoholic beverages and are believed to increase hangover symptoms.

Molecular models of congener compounds: formaldehyde, methanol, acetaldehyde, and ethyl acetate. Congeners (along with ethanol) are produced in alcohol fermentation. Congeners contribute to the flavor and color of alcoholic beverages and are believed to increase hangover symptoms. In the background is a liquor bottle and a glass.
