L-Galactose (Galactose, L-) is a natural product that is widely found in plants and animals. L-Galactose has been shown to be a key intermediate in the molecular pathway for the conversion of D-glucose to oxalic acid in Pistia stratiotes.

Itaconic acid also known as itaconate belongs to the class of organic compounds known as branched fatty acids. These are fatty acids containing a branched chain. Itaconic acid exists as a solid soluble (in water) and a weakly acidic compound (based on its pKa). Itaconic acid has been detected in multiple biofluids such as sweat and urine.

Palmitoleic acid is found to be associated with isovaleric acidemia which is an inborn error of metabolism.
