24hydroxyphenylethylamine

24-hydroxyphenylacetic acid (24-HPPA) is a phenolic acid that has been identified in various biological sources. It is a derivative of phenylacetic acid, a naturally occurring organic compound. The "24" in its name refers to the position of the hydroxyl group on the phenyl ring. 24-HPPA is also known by other names, including 4-hydroxyphenylacetic acid.

This compound has been detected in plants, particularly in fruits and vegetables, where it may contribute to their antioxidant properties. Additionally, 24-HPPA has been found in animal tissues and bodily fluids. Its presence in biological systems suggests a potential role in metabolic pathways or as a signaling molecule. Research has explored its metabolic fate and potential biological activities, including antioxidant and anti-inflammatory effects in some studies. The precise physiological significance and mechanisms of action of 24-HPPA are still areas of ongoing scientific investigation.
