Pentose PO4 Pathway, Fructose, Galactose Metabolism.Pptx
Pentose PO4 pathway, Fructose, galactose metabolism The Entner Doudoroff pathway begins with hexokinase producing Glucose 6 PO4 , but produce only one ATP. This pathway prevalent in anaerobes such as Pseudomonas, they doe not have a Phosphofructokinase. The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt) is a biochemical pathway parallel to glycolysis that generates NADPH and pentoses. While it does involve oxidation of glucose, its primary role is anabolic rather than catabolic. There are two distinct phases in the pathway. The first is the oxidative phase, in which NADPH is generated, and the second is the non-oxidative synthesis of 5-carbon sugars. For most organisms, the pentose phosphate pathway takes place in the cytosol. For each mole of glucose 6 PO4 metabolized to ribulose 5 PO4, 2 moles of NADPH are produced. 6-Phosphogluconate dh is not only an oxidation step but it’s also a decarboxylation reaction. The primary results of the pathway are: The generation of reducing equivalents, in the form of NADPH, used in reductive biosynthesis reactions within cells (e.g. fatty acid synthesis). Production of ribose-5-phosphate (R5P), used in the synthesis of nucleotides and nucleic acids. Production of erythrose-4-phosphate (E4P), used in the synthesis of aromatic amino acids. Transketolase and transaldolase reactions are similar in that they transfer between carbon chains, transketolases 2 carbon units or transaldolases 3 carbon units. Regulation; Glucose-6-phosphate dehydrogenase is the rate- controlling enzyme of this pathway. It is allosterically stimulated by NADP+. The ratio of NADPH:NADP+ is normally about 100:1 in liver cytosol. -

Sweeteners of one kind or another have been found in human diets since prehistoric times and are types of carbohy- drates. The role they play in the diet is constantly debated. Consumers satisfy their “sweet tooth” with a variety of sweeteners and use them in foods for several reasons other than sweetness. For example, sugar is used as a preservative in jams and jellies, it provides body and texture in ice cream and baked goods, and it aids in fermentation in breads and pickles. Sweeteners can be nutritive or non-nutritive. Nutritive sweeteners are those that provide calories or energy — about Sweeteners can be used not only in beverages like coffee, but in baking and as an ingredient in dry foods. four calories per gram or about 17 calories per tablespoon — even though they lack other nutrients essential for growth and health maintenance.

Color and Ash – Is There a Relationship Between Them? Marianne Mckee
Color and Ash – Is there a relationship between them? Marianne McKee, Ronnie Triche and Charley Richard Sugar Processing Research Institute, Inc New Orleans, La 70124 Many questions surround color and ash and a possible relationship between these two components of sugar. Color and ash content of beet and cane sugars including beet, juice, and extract campaign beet sugars as well as raw and refined cane sugars were studied. The appropriate ICUMSA method of determination for color and ash was used for each type of sugar. For beet sugars, ash ranged from 0.003% to 0.015% while color ranged from 20 IU to 57 IU. For the refined cane sugars tested, color ranged from 18 IU to 58 IU while ash ranged from 0.007% to 0.011%. Raw cane sugars ranged from 800 IU to 3335 IU with ash values of 0.173% to 0.317%. These sugars were washed using a high brix white sugar solution to remove the syrup surface layer similar to the affination step in the cane refinery. The samples were dried and then tested for ash and color again after washing. Color and ash removed by washing is believed to be contained in the syrup surface layer surrounding the crystal. These components in the syrup layer are believed to be involved in reactions that promote color increase during storage of sugar. This presentation will show the differences in ash and color in the whole sugar sample as well as in the syrup layer for the various types of sugars studied. INTRODUCTION One of the goals of sugar production is to produce sugar that is low in color and ash whether from sugar beets or sugarcane. -

Objective: To evaluate the additive action of potato starch on the antipseudomonal activity of natural honey. Methods: Physicochemical parameters of 6 samples of Algerian honeys were analysed; four parameters were measured, including Diastase, glucose, fructose and maltose. The antibacterial activity was tested using the well-agar diffusion assay. Results: Six honey samples with initial diastase activity between 22.1 and 7.3 Schade units were tested. Glucose, fructose and maltose values range between 21, 45-30, 95%, 25, 20-37, 81% and 4, 72-78, 45% respectively. The zone inhibition diameter (ZID) for the six honey samples without starch against P. aureogenosa ranged between 26 and 31 mm. When starch was mixed with honey and then added to well, a zone inhibition increase diameter (ZIID) 27 and 32 mm. The percentage increase (PI %) was noticed with each variety and it ranged between 3, 57 and 18, 75%. -
Analysis Fo Sugars in Maple Syrup
APPLICATION NOTE Liquid Chromatography Author: Jamie Foss PerkinElmer, Inc. Shelton, CT Analysis of Sugars in Maple Syrup by Hydrophilic Interaction Introduction Maple syrup is a popular natural Chromatography (HILIC) sweetener that the U.S. Food and Drug Administration defines as the with Refractive Index Detection liquid food derived by concentrating and heat-treating sap from the maple tree.1 Sucrose is the primary sugar found in maple syrup, along with lesser amounts of glucose, fructose and complex carbohydrates.2 Often, the total sugar content of maple syrup is based solely on the amount of sucrose, and does not consider the other sugar sources.2 Maple syrup also contains various other components including minerals, vitamins, amino acids, organic acids, and phytohormones.3 The sugar composition of maple syrup differs from honey, which is dominated by both glucose and fructose, and can contain other sugars such as sucrose and maltose, in much smaller concentrations.3 The analysis of simple sugars is commonly performed using high performance liquid chromatography (HPLC). Often, hydrophilic interaction chromatography (HILIC) is used with refractive index (RI) detection owing to the polarity of the sugars, and the lack of a suitable chromophore for UV detection. Therefore, this work describes a simple HILIC-RI method for the analysis of four common sugars found in maple syrup. The structures of these four sugars are shown in Figure 1.

Sugar Regimes in Major Producing and Consuming Countries in Asia and the Pacific
SUGAR REGIMES IN MAJOR PRODUCING AND CONSUMING COUNTRIES IN ASIA AND THE PACIFIC Mr Kaison Chang, Senior Commodity Specialist, Sugar and Beverages Group, Commodities and Trade Division, FAO. INTRODUCTION Sugar is one of the world's most important crops and one, which is of prominence to countries represented here. It has widespread implications for the earnings and well being of farm communities, as well as for consumers of this important food item. Today it is my task to briefly introduce existing sugar regimes in selected countries in Asia. Before touching on some of the salient features of individual sugar regimes, it is useful to place the Asia and Pacific region in its global context in as far as production, trade and consumption of sugar are concerned. OVERVIEW Of the nearly 128 million tonnes of sugar produced globally more than 36 percent was produced in the Asia and Pacific region with major producing countries being Australia, China, India and Thailand. In terms of trade, the region accounted for 43 percent of global exports and 29 percent of imports in 1998. The major net exporting countries were Australia, Thailand, India and Fiji and net-importing countries included China, Indonesia, Japan, Malaysia and the Republic of Korea. I would like to turn now to some of the features of individual policy in selected countries. My presentation is restricted to only a few countries due to time limitation. However, several more countries are included in the document that has been circulated. AUSTRALIA Introduction Australia's sugar industry is widely acknowledged as one of the lowest cost in the world. -
Fructose, Glucose, and Sucrose in Nature
3/13/2017 Fructose, Glucose, and Sucrose In Nature Fructose, Glucose, and Sucrose In Nature By Rex Mahnensmith | Submitted On July 04, 2016 Fructose, glucose and sucrose are often referred to as fruit sugars, and indeed they are. These sugars exist in virtually all tree fruits, in virtually all vine fruits, and in virtually all berries. Fructose, glucose, and sucrose exist in most root vegetables, as well. Fructose and glucose are circular molecules, very similar to each other. Each has 6 carbon atoms, 6 oxygen atoms, and 12 hydrogen atoms. However, the compounds differ slightly in the arrangements of these atoms. Both exist as straight chain molecules and as circular molecules. Both are highly reactive and will react with each other easily, forming sucrose. Glucose and fructose are two products of photosynthesis, whereby plants inspire carbon dioxide from the atmosphere and react this carbon dioxide molecule with water, forming simple single sugars or "monosaccharides." The photosynthetic steps are complex yet precise, yielding glucose principally, then fructose, and ultimately sucrose, which is the result of fructose combining with glucose to form a double sugar or "disaccharide." In the experimental setting, under direct observation, glucose, fructose, and sucrose appear almost simultaneously through the photosynthetic process. The sugar compositions of glucose, fructose, and sucrose differ from plant to plant. http://ezinearticles.com/?Fructose,Glucose,andSucroseInNature&id=9460795 1/3 3/13/2017 Fructose, Glucose, and Sucrose In Nature For example, apples, figs, bananas, grapes, and pears are relatively rich with free fructose sugars when fructosetoglucose ratios within these fruits are analyzed. -

Low Fructose Diet
Low Fructose Diet What is Fructose? Fructose is a natural sugar found in fruit, fruit juices, honey, and agave syrup. It is also found in some vegetables and wheat products in another form called fructans (fructose sugars in a long chain). High fructose corn syrup (HFCS) is another form of fructose commonly used in processed foods. What is Fructose Intolerance? Fructose intolerance, also called dietary fructose intolerance or fructose malabsorption, happens when a person cannot properly absorb normal amounts of fructose (>25 grams per meal). What are common symptoms? Unabsorbed fructose that reaches the large intestine can be fermented (converted into gas) by bacteria causing symptoms like abdominal pain, gas, belching, and bloating. Unabsorbed fructose can also pull water back into the colon, increasing gut motility and causing diarrhea. Less common symptoms of fructose intolerance can include reflux, depression, fatigue, brain fog, headache, weight loss, and sugar cravings. How is Fructose Intolerance diagnosed? Anyone can develop fructose intolerance, but it is more common among individuals with irritable bowel syndrome (IBS) or other gastrointestinal disorders. A Hydrogen Breath Test is used to diagnosis fructose intolerance. An abnormal (positive) test indicates the need for a low fructose diet. What is a Low Fructose Diet? A low fructose diet reduces the amount of fructose consumed by limiting or avoiding foods with excess fructose (foods that contain more than half of their natural sugar as fructose), foods with high fructose (more than 3 grams), and foods that are a significant source of fructans (chains of fructose). How long does this diet need to be followed? A low fructose diet should be followed until symptoms improve, typically 2-6 weeks.
