Uridine diphosphate glucuronic acid ammonium (UDP-α-D-glucuronic acid ammonium) is a precursor of many plant cell wall polysaccharides and is required for the production of seed mucilage.

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.

Palmitoylcarnitine (Palmitoyl DL-carnitine) is a mitochondrial fatty acid oxidation intermediate that acts as a surfactant.
