karboksyyl
Karboksyyl, commonly referred to in English as the carboxyl group, is a functional group in organic chemistry with the formula –COOH. It consists of a carbonyl carbon (C=O) bonded to a hydroxyl group (–OH) on the same carbon. This arrangement gives the group distinctive acidity and reactivity, and it is the defining feature of carboxylic acids.
Structure and properties: The carboxyl carbon is double-bonded to oxygen and single-bonded to hydroxyl; resonance between
Reactions: The carboxyl group participates in esterification with alcohols to form esters and water, and in
Nomenclature and examples: When the carboxyl group is the highest-priority functional group, the parent compound is
Biological and industrial relevance: Carboxyl groups are ubiquitous in biomolecules such as amino acids and fatty
