For the Rice Chex pellets, a 3% (0.0475 gram sucrose/1.5837 gram Rice Chex) and 5%(0.0777 gram sucrose/1.4813 gram Rice Chex) by calorie sucrose and Rice Chex mixture was used.
The Rice and Corn Chex cereals were samples that were to be tested and the sucrose was used to serve as an adhesive for the Rice and Corn Chex pellets.
Even when sucrose was added to the “dry” Chex, no matter how much sucrose was added, a stable pellet was unable to be formed.

 Welcome to the webpage of my final year BSc dissertation project!
Sucrose along with agar are the major components in the media to affect the uptake of water by plant cells (Seetohul, 1995).
Moreover, on autoclaving sucrose is partly hydrolysed to glucose and fructose (Ball, 1953).
Sucrose synthase usually catalyses sucrose synthesis but in storage tissues, where the concentration of sucrose is high, the reverse occurs (Avigad and Dey, 1997).

 Sucrose Gradients
If the sucrose does not begin flowing through the tubing (this often occurs if the tubing is still moist from prior gradient-making runs), suction it along by attaching the suction bulb tubing to the end of the capillary tubes.
Add a 1 ml 60% sucrose cushion to the bottom of the gradients by drawing 60% sucrose up in a syringe fitted with a long blunt-end needle.
Great: pick lines that are flowing well, stick them in the ultracentrifuge tubes, and open the mixer between the two sucrose solutions (make sure you see high-concentration sucrose being whipped into the outlet side of the gradient maker).

 Is Fructose Dangerous?
Many widely used products, like sucrose, were grandfathered in as a safe product when food and drug regulations were created early in 1938, and the safety of fructose was assumed based on the perceived safety of sucrose.
Sucrose is affirmed as GRAS (generally regarded as safe)," explained Judy Folke, a spokesperson at the FDA's Food Safety and Applied Nutrition Press Office in Washington,D.C. "Fructose is not GRAS, but it was treated under prior sanction because it had been used for so many years."
Sucrose also raised blood pressure and increased the fragility of blood platelet cells, making them more prone to clotting.

 ific.org : Sugars & Low-Calorie Sweeteners
Sucrose is derived from sugar cane or sugar beets.
Fructose is a constituent of sucrose and is often referred to as fruit sugar because of its presence in fruits.
While many people associate sweetness with sucrose or table sugar, sucrose is just one type of sugar that provides this taste.

 Sucrose for analgesia in newborn infants undergoing painful procedures
Sucrose in a wide variety of dosages was generally found to decrease physiologic (heart rate) and behavioural (the mean percent time crying, total cry duration, duration of first cry, and facial action) pain indicators and composite pain scores in neonates undergoing heel stick or venepuncture.
Sucrose has been examined for its calming effects in crying newborns (Barr 1993, Barr 1994, Haynes 1995, Smith 1992) and its pain-relieving effects for invasive procedures in term and preterm neonates (Stevens 1997a).
In a systematic review/meta-analysis of the efficacy of sucrose for procedural pain management, Stevens (Stevens 1997a) found that proportion of time crying was decreased with 0.24 - 0.48 g (2ml of a 12-24% sucrose solution) administered orally 2 minutes prior to a painful procedure (heel lance or venepuncture).

 Relationship among sucrose, mutans streptococci and caries
Considering that sucrose is also a fermentable carbohydrate, the maintenance of a low pH may induce an ecological change in dental plaque, with an increase in mutans streptococci levels (4).
Eight times exposure to sucrose is equivalent to consuming meals or snacks containing this sugar at the same frequency, e.g., 3 meals and 5 snacks or coffee consumption with sucrose.
When sucrose was used 2 or 4 times/day, the percentage was 5% and 11%, respectively, which were not statistically different from the control.

 Psychological Record, The: Positive induction produced by food-pellet reinforcement: Component variations have little effect
In their experiment, rats responded for sucrose reinforcement in the first half of the session on one lever and for food-pellet reinforcement in the second half of the session on a separate lever.
However, response rates on the lever delivering sucrose reinforcers were still higher than observed in the control condition in which sucrose reinforcement was available during both halves of the session (i.e., induction was still observed).
Across conditions, the period of sucrose reinforcement was followed by 0, 10, 20, 30, or 40 min of food-pellet reinforcement.

 Food consumption and individual lifespan of adults of the blowfly, Calliphora stygia: a test of the 'rate of living' theory of aging.
Blowflies provided with 0.125M sucrose (N=59) consumed daily a significantly greater amount of the sucrose solution than those provided with 0.2M sucrose (n=55) such that the average rates of sucrose consumption were, respectively, 1.72 and 1.96mg sucrose day(-1).
Following eclosion, adult Calliphora stygia were individually housed (at 22 degrees C and 73% RH) in 125ml plastic vials and provided with ad libitum access to either 0.125 or 0.2M sucrose as a food source and daily food consumption measured throughout their adult life.
All blowflies were weighed daily and food consumed is determined by weighing individual food dishes.

 Prepared Foods: Sweeteners Combine for Tasteful Calorie Reduction - Brief Article
Sunett can reach 9 or 10% sweetness (sucrose equivalent) in a beverage.
Sunett in combination with one of these delivers a flavor impact that has a similar slope to sucrose.
When Sunett and other high-intensity sweeteners replace sucrose in baked goods, formulators include sugar alcohols like sorbitol or isomalt, and bulking agents like polydextrose or maltodextrin to restore those functions.

 Genetic evidence for the in planta role of phloem-specific plasma membrane sucrose transporters -- Gottwald et al. 97 (25): 13979 -- Proceedings of the National Academy of Sciences
The loading of sucrose into the sieve elements of source leaves is an important and basic physiological process in plants.
With no sucrose, the 10-day-old homozygous mutant seedling (arrow) is much smaller and slower in development than its heterozygous and wild-type siblings, having only cotyledons and very short roots.
A major question in plant physiology is how the large amount of sucrose made in leaves is transported to the rest of the plant.

 Carbohydrates - Sucrose
Sucrose or table sugar is obtained from sugar cane or sugar beets.
When sucrose is hydrolyzed it forms a 1:1 mixture of glucose and fructose.
There are no hemiacetals remaining in the sucrose and therefore sucrose is a non-reducing sugar.

 Dna encoding sucrose pts enzyme II - Patent 6893852
As a result, it was revealed that the DNA fragment containing the aforementioned sucrase gene consisted of two independent cloned fragments ligated to each other, and it was found that a novel gene encoding sucrose PTS enzyme II existed downstream from the sucrase gene.
In coryneform bacteria, non-PTS specific for sucrose is not known, but, for example, if sucrase is allowed to act extracellularly, glucose and fructose can be taken up by non-PTS.
Therefore, if sucrose PTS is disrupted and sucrose can be taken up by an uptake system which does not require PEP, it is considered advantageous in view of sucrose uptake rate or productivity of an amino acid or the like.

 Relationship among sucrose, mutans streptococci and caries
The purpose of this study was to investigate the relationship among frequency of sucrose exposure, mutans streptococci levels and dental caries.
An increase of mutans streptococci would be expected according to sucrose exposure considering that a frequent low pH in dental plaque would be an ecological factor for its growth (4).
The data show that there was a tendency for higher counts of mutans streptococci in dental plaque and higher enamel mineral loss according to frequency of sucrose exposure.
