additional information 4-nitrophenyl derivatives serve as substrates, in decreasing order: beta-fucoside, beta-glucoside, beta-galactoside, beta-xyloside. The corresponding 2-nitrophenyl glycosides are less well accepted. No hydrolysis is found with alpha-glycosides and beta-thioglucoside Avena sativa ?
