carboxylaattiryhmien

Carboxylaattiryhmä is the Finnish term for a carboxylate group. A carboxylate group is the negatively charged conjugate base of a carboxylic acid. It has the general formula RCOO-, where R represents an organic substituent or hydrogen atom. The carboxylate group is characterized by a carbon atom double-bonded to one oxygen atom and single-bonded to another oxygen atom, which carries a negative charge. This arrangement results in resonance stabilization, where the negative charge is delocalized over both oxygen atoms.

Carboxylate groups are important functional groups in organic chemistry and biochemistry. They are found in many important molecules, including amino acids, fatty acids, and carboxylic acids themselves. The negative charge of the carboxylate group makes it hydrophilic, meaning it readily interacts with water. This property influences the solubility and behavior of molecules containing carboxylate groups. Salts of carboxylic acids are called carboxylates. For example, sodium acetate (CH3COONa) is the sodium salt of acetic acid, and it contains the acetate anion (CH3COO-). In biological systems, carboxylate groups are often involved in acid-base reactions and in forming ionic interactions with positively charged molecules.
