Definition: a Carboxylic acid is an organic compound
containing a Carboxyl group ( C=O ). with an hydrogen and a R group bonded to the carconyl carbon.
R represent groups such as an aliphatic group .
The molecule on the left (acetic acid) highlight the functional group (the 3 remaining hydrogen atoms are drawn in green for
The Carboxyl group is generaly written -COOH

Carboxylic acids are the most important acids of organic chemistry. They are present or in derived
form in many natural substances:
Amino acids (building blocks of proteins). Note that the amino acids also contain an
Below is given the structure of alanine
Fatty acids (building blocks of lipids) are long aliphatic chains terminated by the carboxyl
The structure of stearine is given below.
