p-Coumaric acid glucoside is a hydroxycinnamic acid, an organic compound found in commercial breads containing flaxseed.[1]
Biosynthesis
The glucoside is produced by enzymes which add a glucose unit from UDP-glucose to the parent p-coumaric acid. The cis and trans isomers have enzymes specific to each. Thus hydroxycinnamate 4-beta-glucosyltransferase characterised from tomato gives the trans form:[2]

However, cis-p-coumarate glucosyltransferase in Sphagnum fallax gives the cis equivalent:[3]
