pkoumaroyl

p-Coumaroyl is a term that can refer to two related chemical entities: p-coumaric acid and the p-coumaroyl group. p-Coumaric acid, also known as 4-hydroxycinnamic acid, is a phenolic acid found in many plants. It is a common component of plant cell walls and plays a role in lignin biosynthesis. It is also a precursor to other important plant compounds.

The p-coumaroyl group is the acyl radical derived from p-coumaric acid. This group is often found esterified to other molecules, particularly carbohydrates and proteins, within plant tissues. For example, it is attached to arabinoxylans in cereal grains, contributing to their structural integrity and affecting their processing properties. The presence of p-coumaroyl groups can influence the solubility and digestibility of these polysaccharides.

In biological contexts, p-coumaroyl compounds are studied for their potential antioxidant and anti-inflammatory properties. Research has investigated their roles in plant defense mechanisms and their impact on human health when consumed as part of a diet. The biosynthesis of p-coumaric acid occurs through the phenylpropanoid pathway in plants.
