متن کاملThe biosynthesis of sucrose phosphate.
The enzymic formation of sucrose from UDPGl and fructose has been described in the preceding paper (1). While some preparations of the enzyme were found to be almost devoid of action of fructose-6-phosphate, other extracts catalyzed the formation of free sucrose either from fructose or from its phosphate. Since these extracts contain phosphatase, it seemed likely that the action on fructose pho...
متن کاملThe synthesis of sucrose by extracts of the root of the sugar beet.
There is no doubt that synthesis of sucrose does occur in the leaf of the sugar beet but the root has not previously been shown to possess a sucrosesynthesizing system. Buchanan et al. (1952) and Buchanan (1953), in photosynthetic experiments with 14CO2, demonstrated the formation of sucrose phosphate in the leaves of the sugar beet as well as of other plants. They postulated that the sucrose p...
متن کاملSucrose translocation and storage in the sugar beet.
Several physiological processes were studied during sugar beet root development to determine the cellular events that are temporally correlated with sucrose storage. The prestorage stage was characterized by a marked increase in root fresh weight and a low sucrose to glucose ratio. Carbon derived from (14)C-sucrose accumulation was partitioned into protein and structural carbohydrate fractions ...
متن کاملSucrose uptake and compartmentation in sugar beet taproot tissue.
Active sucrose uptake by discs of mature sugar beet (Beta vulgaris L. cv GW-D2 and USH-20) root tissue shows a biphasic dependence on external sucrose. At concentrations up to 20 millimolar sucrose, the active uptake mechanism appears to approach saturation, with an apparent K(m) of 3.6 millimolar. At higher external sucrose concentrations, a linear dependence becomes obvious indicating the pro...
