Karboksi

Karboksi is a term that can refer to several different concepts, primarily in chemistry and biology. In its most general chemical sense, it relates to the carboxyl group, a functional group with the formula -COOH. This group consists of a carbonyl group (C=O) bonded to a hydroxyl group (-OH). Carboxyl groups are acidic and are found in carboxylic acids, a major class of organic compounds. These acids play crucial roles in various chemical reactions and are fundamental building blocks in organic chemistry.

In a biological context, "karboksi" might refer to molecules containing carboxyl groups, such as amino acids. Amino acids are the monomers that make up proteins, and they possess both an amino group (-NH2) and a carboxyl group (-COOH). The presence of the carboxyl group is essential for the zwitterionic nature of amino acids and their ability to form peptide bonds. Furthermore, carboxyl groups are involved in metabolic pathways like the citric acid cycle, where they are decarboxylated, releasing carbon dioxide.

The term can also appear in specific scientific names or as part of compound names, indicating the presence of one or more carboxyl groups. Understanding the function and properties of the carboxyl group is therefore key to comprehending many areas of chemistry and biochemistry.
