4-Hydroxybenzoic acid 4-O-glucoside is a glucoside of p-hydroxybenzoic acid. It can be found in mycorrhizal (Picea abies-Lactarius deterrimus and Picea abies-Laccaria amethystina) and non-mycorrhizal roots of Norway spruces (Picea abies).
Biosynthesis The enzyme 4-hydroxybenzoate 4-O-beta-D-glucosyltransferase, which is found in the pollen of Pinus densiflora, adds a glucose unit from UDP-glucose to 4-hydroxybenzoic acid and gives the 4-O-glucoside.
