They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino acids are characterized by their central carbon atom, known as the α-carbon, which is bonded ...

When it comes to supramolecular chemistry, the carboxylic acid group -- and its conjugate carboxylate ... been no exhaustive classification of these carboxyl(ate) motifs present in crystal ...

Proteins are made of amino acid chains, or polypeptides. Amino acids have a basic backbone made of an amino group and a carboxyl group, and differ in their side-chains. These polypeptide chains of ...

To make an ester, a hydrogen atom must be removed from the hydroxyl group (–OH) of the alcohol. The –OH portion of the acid's carboxyl group must also be removed. The hydrogren atom and the ...
