PPA (Cat No.:I045255) is a small organic compound belonging to the phenylpropanoid family, characterized by a phenyl ring linked to a three-carbon chain ending in a carboxylic acid group. Naturally occurring in plants, PPA serves as a precursor or intermediate in the biosynthesis of various secondary metabolites, including flavonoids, lignins, and coumarins. It exhibits antioxidant, anti-inflammatory, and antimicrobial properties, making it relevant for pharmacological and nutraceutical research. PPA is also used in studying plant defense mechanisms, metabolic engineering, and synthetic biology for producing bioactive phenylpropanoids with therapeutic and industrial applications.
