Acceptor alcohols (ROH) include methanol, ethanol and propanol. No cofactors are required as 1-O-trans-cinnamoyl-beta-D-glucopyranose itself is an "energy-rich" (activated) acyl-donor, comparable to CoA-thioesters. 1-O-trans-Cinnamoyl-beta-D-gentobiose can also act as the acyl donor, but with much less affinity.
