Carboxylic acids can undergo reduction reactions. Reduction is the opposite of oxidation. For example, ethanoic acid (CH 3 COOH) can be formed by the oxidation of ethanol as shown below.

A carboxylic acid is one which contains -COOH as its functional group. In comparison to mineral acids, carboxylic acids show some similarities, but also, some important differences.

The most common is to begin numbering the carbons from the carboxylic acid functional group, with that carbon labeled as carbon 1. Following this system, linoleic acid has double bonds at the 9 ...

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.

A carbon atom is located at the center of an amino acid. The carbon atom forms a bond with a hydrogen atom, an amino group, a carboxylic acid group, and an R group. An R group is a unique side ...
