karboksüülimisel

Karboksüülimisel is a chemical process in which a carboxyl group (COOH) is added to a molecule. This reaction is a fundamental transformation in organic chemistry and plays a crucial role in various biological and industrial processes. Carboxylation can occur through several different mechanisms, often involving carbon dioxide as the source of the carboxyl group. One common method is the Kolbe-Schmitt reaction, which is used industrially to produce salicylic acid. In biological systems, carboxylation is essential for the synthesis of many important compounds, including fatty acids, amino acids, and neurotransmitters. Enzymes called carboxylases typically catalyze these biological carboxylation reactions, often requiring cofactors like biotin. The addition of a carboxyl group can significantly alter the chemical properties of a molecule, often increasing its polarity and acidity. This change can lead to new reactivities and functionalities, making carboxylation a valuable tool for chemists in the synthesis of complex organic molecules. Understanding the principles of carboxylation is key to comprehending a wide range of chemical and biochemical pathways.
