the saccharides produced in the presence of d-glucose , d-mannose , and d-xylose were all non-reducing disaccharides and were identified as beta-d-fructofuranosyl-alpha-d-glucopyranoside ( sucrose ) , beta-d-fructo-furanosyl-alpha-d-mannopyranoside ( mannosucrose ) , and beta-d-fructofuranosyl-alpha-d-xylopyranoside ( xylsucrose ) , respectively .
