p-Coumaric acid (CAS 501-98-4)

p-Coumaric acid, a hydroxycinnamic acid derivative characterized by the presence of a phenolic ring and an unsaturated carboxylic acid group, plays a pivotal role in the plant kingdom and in various research fields due to its significant biological activities. Its mechanism of action is primarily attributed to its antioxidant properties, where it acts as a free radical scavenger, mitigating oxidative stress within cells. This compound is also involved in the biosynthesis of lignin, a critical structural polymer in plant cell walls, enhancing plant rigidity and resistance against pathogens. In research applications, p-Coumaric acid is utilized as a model compound to study phenolic biosynthesis pathways and to understand the ecological interactions between plants and their environment, including stress response mechanisms. Its ability to absorb UV light makes it an interesting candidate for studying natural photoprotection mechanisms in plants. Furthermore, its role as a precursor in the synthesis of other biologically significant compounds, such as flavonoids and stilbenes, underscores its importance in metabolic engineering efforts aimed at producing bioactive compounds with potential applications in agriculture and materials science.
