Fatty acids are the fundamental building blocks of many lipids and play crucial roles in metabolism. The primary functional group of a fatty acid is the carboxyl group, which gives the molecule its acidic nature and reactivity.

With an unpleasant odor often likened to rancid butter, butanoic acid, also known as butyric acid, is a common compound in both industrial and biological settings. It is systematically classified as an alkyl carboxylic acid, a category of organic compounds defined by a specific functional group.

Found famously as a component of milk sugar, lactose, D-galactose is a monosaccharide whose classification depends entirely on its chemical structure. The question, "is D-galactose a ketose or aldose," is fundamental to understanding this sugar and is answered by identifying its primary functional group.
