Dry ready-to-eat sugar-added cereals combine refined sugar and starch. When those carbohydrates are consumed bacteria in the dental plaque on tooth surfaces produce acids says Christine Wu professor of pediatric dentistry
but the added sugar can be a risk to dental health Wu said. Our study results show that only milk was able to reduce acidity of dental plaque resulting from consuming sugary Froot Loops said Naval who is currently a fellow at the Centers for Disease Control and Prevention in Atlanta.
Eating cereal combined with milk lowered plaque ph to levels similar to that obtained after rinsing with a 10 percent sugar solution.
Eating sugar-added cereal with milk followed by drinking fruit juice is thus a highly cavity-causing combination Wu said.
Studies of food intake and cavities have focused mainly on the sugar or carbohydrate content. Fewer studies have looked at how combinations of food and the order in

Fructose and dextrose are simple sugars found naturally in plants. We studied fructose because it is the most commonly added sugar in the American diet
but based on our study findings we can't say conclusively that fructose caused the liver damage Kavanagh said.
What we can say is added that high sugars caused bacteria to exit the intestines go into the blood stream
To fuel production of these fruiting bodies the fungus needs sugar which comes in the form of long cellulose molecules packed inside the leaf clippings the ants deliver.
To get at the sugars the fungus produces enzymes that break the cellulose apart into glucose subunits.
Accessing and deconstructing cellulose is also the goal of GLBRC researchers who want to ferment the stored sugars to ethanol and other advanced biofuels.
The EBI is working on how to get the sugars out of plants and how to turn those to alcohols.

Catalyzing more sugars from biomasscatalysis may initiate almost all modern industrial manufacturing processes but catalytic activity on solid surfaces is understood poorly.
This is especially true for the cellulase enzymes used to release fermentable sugars from cellulosic biomass for the production of advanced biofuels.
technique called PALM--for Photo-Activated Localization Microscopy--the researchers have found a way to improve the collective catalytic activity of enzyme cocktails that can boost the yields of sugars for making fuels.
Increasing the sugar yields from cellulosic biomass to help bring down biofuel production costs is essential for the widespread commercial adoption of these fuels.
The enzymatic breakdown of cellulosic biomass into fermentable sugars has been the Achilles heel of biofuels a key economic bottleneck says chemical engineer Harvey Blanch one of the leaders of this research.
Synthesized from the sugars in the cellulosic biomass of grasses other non-food crops and agricultural waste advanced biofuels represent a sustainable nonpolluting source of transportation fuel that would also generate domestic jobs and revenue.
Unlike the simple starch-based glucose sugars in corn and other grains the sugars in cellulosic biomass are complex polysaccharides that must be extricated from a tough polymer called lignin
Instead of sunlight energy for the microalgae's growth comes from low-cost plant-based sugars. This gives the company a completely consistent repeatable industrial process to produce tailored oil at scale Sugar from traditional sources such as sugarcane

Ultimately cellulosic sources of sugars from non-food plants or plant waste materials like grasses or corn stover may take over as those technologies reach the right scale
This gene codes for an enzyme that digests sugar. It might be used to digest woody tissue
Bees were trained to know that sugar could be found on flowers where other foragers were present.
She found that it was mediated by droplets of sugar esters called acylsugars that are produced and exuded from hairs (trichomes) that cover the plants.
Whether it be altering sugar levels to suit different environments or tweaking virus resistance Mutschler-Chu wants to discover the best package for insect and virus control.
The key to this exciting development is that Zhang is using the second most prevalent sugar in plants to produce this hydrogen he said.
Other processes that convert sugar into biofuels such as ethanol and butanol always have energy efficiencies of less than 100 percent resulting in an energy penalty.
Its flowers are large producing a high volume of sugar-rich nectar each day--an ideal place for bumblebees to forage.
Again the experiments mimicked levels that could be seen in the wild this time by feeding a sugar solution mixed with appropriate levels of pesticides.
The results published in the journal Public health Nutrition confirm that parents with a lower level of education feed their children food rich in sugars

Sugars are produced in the leaves of the maple tree by photosynthesis with the help of absorbed water carbon dioxide
In the period between this dormant state and the active growing season (during cold nights with below-freezing temperatures followed by mild warm days with above-freezing conditions) the stored starch is converted into sugar
Osmotic pressure which exists due to differences in sugar concentration between different components of the vascular tissue helps maintain stable gas bubbles
or easy for enzymes to turn the biomass into sugars? Differences in cell walls are enormous
and insect resistance but it can stand in the way of enzymes that want to get at the sugars locked up in the carbohydrates.
It's the deconstruction of the raw sugars that produces the sugars the biofuels industry finds valuable.
The ratios of lignin to carbohydrate components together with the intensity of the lignin peaks can tell a scientist how easily a plant will give up its sugars.
or some other factor affecting recalcitrance (the plant's resistance to give up its structural sugars).

for both forms. Pellets because of their higher energy density would be preferred the form. Our work is the first demonstration that ionic liquid pretreatments can effectively handle mixed
We're continuing the collaboration to next identify the most economical pelletized feedstock mixtures based on targeted regions of the United states. We''then determine how efficiently our process can convert these mixtures into fermentable sugars.
The effect creates an excess of strengthening sugar molecules in the willows'stems which attempt to straighten the plant upwards.
These high-energy sugars are fermented into biofuels when the trees are harvested in a process that currently needs to be more efficient before it can rival the production of fossil fuels.
and that it can be easier to release sugars from this wood. This is an important breakthrough our study now shows that natural genetic variations are responsible for these differences
Their measurements confirmed that the willows here could release five times more sugar than identical trees grown in more sheltered conditions at Rothamsted Research in the south of the UK.
Other rocks nearby are siltstone with grains finer than powdered sugar. These differ significantly from pebbly conglomerate rocks in the landing area.

So our job is not to say'Hey we can't have any sugar-containing beverages
which accelerate plant biomass conversion into sugars and further into products such as bioethanol. The project's results include lignin-tolerant enzymes and enzyme cocktails for processing spruce straw corn cob and wheat bran.
The EU's DISCO project developed powerful enzymes and enzyme cocktails suitable for various raw materials with the purpose of converting agricultural side streams into fermentable sugars and further into products such as bioethanol.
which can be converted industrially into fermentable sugars with the help of enzymes. Microbes can then be used to produce various chemicals such as bioethanol from the sugars.
Lignocellulosic biomass contains substantial amounts of lignin which interferes with enzyme activity. The DISCO project produced new knowledge on the inactivating property of lignin

#Sugars in the cornfield: Plants use defenses against pests, but they dont always worksugars are usually known as energy storage units in plants
But sugars may also be part of a deadly game of tag between plant and insect according to scientists at the Max Planck Institute for Chemical Ecology.
Grasses and crops such as maize attach sugars to chemical defenses called benzoxazinoids to protect themselves from being poisoned by their own protective agents.
Then when an insect starts feeding a plant enzyme removes the sugar to deploy the active toxin.
When the researchers examined the frass of these pests â pests that cause enormous crop damage â they found the toxin with sugar still attached.
After the plant removes the sugar the insect reattaches it but in the opposite stereochemical configuration.
Attaching the sugar in the opposite configuration turns out to be a very simple but effective detoxification strategy
which cleaves DIMBOA-glucoside to release the sugar. The free DIMBOA formed as a result causes many insects to die
Caterpillars of the fall armyworm and two other Spodoptera species deploy a gut enzyme that catalyzes the attachment of a sugar to the toxic free DIMBOA.
The sugar group is reattached in a mirror-image orientation (forming a (2s)- DIMBOA-glucoside) so that the plant enzyme cannot remove it a second time.
Their study reported in the Proceedings of the National Academy of Sciences is the first to use biochemical approaches to confirm the hypothesis that microbes in the human gut can digest fiber breaking it down into simple sugars
but also for biofuels production since the same sugars can be fed to yeast to generate ethanol and other liquid fuels.
so that other enzymes can work on it to break it down into its unit sugars. Working with U. of I. biochemistry professor Satish Nair the researchers also noticed that the CBM put a kink in the fiber
so it can get to work breaking the bonds between the sugars. Further research is needed to confirm this hypothesis Cann said.

Their discovery required an international team of scientists fieldwork in the California mountains and at Harvard university's Concord Field Station plus collaborations from Harvard labs on both sides of the Charles river.
If they are missing the single sweet receptor how are they detecting sugar? More bird genomes were sequenced and still no sweet receptor.
Amino acids and sugars look very different structurally so in order to recognize them and sense them in the environment you need acompletely different lock and key.
New results pave the way for closed loop biofuel refinerieswhile the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose
The cellulosic sugars stored in the biomass of grasses and other non-food crops and in agricultural waste can be used to make advanced biofuels that could substantially reduce the use of the fossil fuels responsible for the release of nearly 9 billion metric tons of excess carbon into the atmosphere each year.
This means economic technologies must be developed for extracting fermentable sugars from cellulosic biomass and synthesizing them into fuels and other valuable chemical products.
A major challenge has been that unlike the simple sugars in corn grain the complex polysaccharides in biomass are embedded deeply within a tough woody material called lignin.
Researchers at JBEI have been cost-effectively deconstructing biomass into fuel sugars by pre-treating the biomass with ionic liquids--salts that are composed entirely of paired ions
After 73 hours of incubation with these new bionic liquids sugar yields were between 90-and 95-percent for glucose and between 70-and 75-percent for xylose.
