karboxýlhópi

The karboxýlhópi, also known as the carboxyl group, is a functional group in organic chemistry. Its chemical formula is COOH. It consists of a carbonyl group (C=O) and a hydroxyl group (OH) attached to the same carbon atom. This arrangement gives the carboxyl group its characteristic properties.

The karboxýlhópi is a key component of carboxylic acids, which are organic compounds containing one or more carboxyl groups. These acids are known for their acidic nature due to the ability of the hydrogen atom in the hydroxyl group to dissociate as a proton (H+). This makes carboxylic acids capable of donating a proton to a base.

The karboxýlhópi is also a significant functional group in many biological molecules. It is found in amino acids, the building blocks of proteins, where it contributes to the overall structure and reactivity of these essential biomolecules. Fatty acids, which are important components of lipids and cell membranes, also contain a karboxýlhópi.

The presence of a karboxýlhópi in a molecule can influence its physical properties such as solubility and boiling point. The polar nature of the karboxýlhópi allows it to form hydrogen bonds, which can increase solubility in polar solvents like water and lead to higher boiling points compared to non-polar compounds of similar molecular weight.
