Keto acid

Keto acid

Keto acids are organic acids containing a ketone functional group and a carboxylic acid group.

Common types of keto acids include:
*Alpha-keto acids, or 2-oxo acids, such as pyruvic acid have the keto group adjacent to the carboxylic acid
*Beta-keto acids, or 3-oxo acids, such as acetoacetic acid have the ketone group at the second carbon from the carboxylic acid
*Gamma-keto acids, or 4-oxo acids, such as levulinic acid have the ketone group at the third carbon from the carboxylic acid
