the uptake kinetics of sucrose and the sugar alcohol , mannitol , which are both phloem-translocated , indicated presence of a single saturable system , while uptake of non-phloem sugars ( glucose and 3-o-methylglucose ) exhibited biphasic kinetics with lower uptake rates than those for sucrose and mannitol .
