in this study, the effect of edible coating and osmotic dehydration, as pre-treatments before drying of cucurbit, were investigated. cucurbit samples were cut spirally and coated by carboxy methyl cellulose (cmc) 1% and ascorbic acid 0.1% solutions and then processed by osmotic dehydration. proportion of sample to solution was 1:10 and the solution containing sucrose %45, salt%25 and citric aci...

For induction of ruminal acidosis, 10 clinically healthy three years old non pregnant female sheep were selected. Prior to the infusion of sucrose (0 hour), rumen and blood samples were obtained in order to determine baseline rumen and blood pH, respectively. Electrocardiogram (ECG) was also recorded. Acute ruminal acidosis was induced experimentally with sucrose at a dose of 18g kg-1 body weig...

Different parts of the rice (Oryza sativa L.) plant at different growth stages were analyzed for sucrose synthase (SS) by enzyme activity assay and enzyme-linked immunosorbent assay directly on the extracts or on the eluates from a gel filtration column. On a dry matter basis, the amount of soluble protein and SS activity decreased significantly, but the amount of enzyme protein changed little ...

Several lines of evidence indicate that the partitioning of photosynthate between starch and sucrose is influenced by the relative concentrations of inorganic phosphate (Pi) in the cytosol and chloroplast. Two greenhouse experiments were conducted to determine the influence of long-term differences in soil P levels, ranging from deficient to supraoptimum, on leaf starch and sucrose concentratio...

BACKGROUND/AIMS In our previous studies, rats on insulin treatment (5 U/day) and oral glucose to avoid hypoglycemia had reduced neointimal growth after arterial injury. However, plasma glucose in the insulin-treated rats was lower than normal and the effect of oral glucose remained undetermined. In this study, the effects of normoglycemic hyperinsulinemia and oral glucose or sucrose were invest...

The rapid hemolysis by fresh guinea pig serum known to occur with neuraminidase-treated sheep red cells has been investigated with respect to the immunological and physiological properties of the lytic process. The following observations were made: (a) The susceptibility to hemolysis is directly proportional to the amounts of neuraminic acid enzymatically released from the cell surface. Complem...

Sucrose consumption data of the sucrose group (n = 33) of a 2-yr longitudinal study was plotted against salivary sucrase activity values obtained during this 2-yr period. The correlation coefficients varied between 0.194 and 0.551. The subjects were divided into high (greater than or equal to 10 mumol x min-1 x (10(-3)) and low (less than 10) sucrase activity subgroups. There were significant d...

The maize (Zea mays) leaf is a valuable system to study the sucrose import to sucrose export transition at the cellular level. Rapidly growing and fully heterotrophic cells in the basal part of the young leaf showed a high sucrose synthase (SS) activity. Leaf SS has been purified to homogeneity. By comparison with purified kernel SS isozymes, the leaf SS has been identified as SS(2). SS(1) prot...

Samples (2ml) of a 605g,,. supernatant were applied to continuous linear gradients of 0.74-2.45 M-sucrose in 16 ml, on a cushion of 2ml of 2.45 M-sucrose. Centrifugation was at 4°C in a 3 x25ml swing-out rotor, and the integrated field-time was 562000g-min at ray. 9.39cm. Fractions (1 ml) were collected by displacement with 2.45~-sucrose. The letters A-D indicate the positions of the four fract...

1. A formula breakfast containing protein, carbohydrate and fat was given on two occasions to nine middle-aged male convalescent patients and to ten young men. The meals differed only in the type of carbohydrate given; sucrose or an isocalorific amount of glucose. 2. After the formula meal containing sucrose; (a) the alimentary lipaemia was cleared more slowly; (b) insulin response was smaller,...
