The new method enables what had been impossible except in narrow cases: creating a center of chiral asymmetry at a hard-to-reach position called the "gamma" position on a cyclic carboxylic acid.

an 18-carbon saturated fatty acid. The normal numbering system, starting with the carboxylic acid, is shown in blue. The carbons and oxygens of the carboxylic acid functional group are red.

Carboxylic acids are weak acids, and will react more slowly than other, stronger acids like hydrochloric acid. A carboxylic acid is an organic compound with a -COOH functional group. Carboxylic ...

Citing previous research into the attractiveness of carboxylic acid, a molecule that is part of the skin’s moisturizing layer, the Rockefeller scientists performed a chemical analysis looking ...

Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the α carbon. Each of the 20 amino acids has a specific ...

Esters are usually synthesized from an alcohol and an acid, most frequently, a carboxylic acid. In some cases, an epoxide is used instead of the alcohol; or an acid halide or anhydride replaces the ...

With the reported method, fluorine atoms can be introduced directly into complex carboxylic acid molecules without a tedious and time-consuming synthesis. "Due to the importance of both carboxylic ...
