Pelargonidin
Glycosides
In many plant systems, Pelargonidin can be added to a glucose molecule to form Pelargonidin 3-glucoside (callistephin). Acylated pelargonidin glycosides can be found in red-purple flowers of Ipomoea purpurea.

Flavonol 3-O-glucosyltransferase
One specific example would be this enzymes actions on pelargonidin. Flavonol 3-O-glucosyltransferase binds the glucoside to this protein, making pelargonidin 3-O-glucoside.
