What Is Fructose? What Is Fructose? Fructose Is a Natural Sugar Found in Many Fruits, Vegetables, and Honey WHAT IS FRUCTOSE? What is fructose? Fructose is a natural sugar found in many fruits, vegetables, and honey. It is the sweetest of the naturally occurring nutritive (caloric) sweeteners and has many unique functional and nutritional properties that make it a valuable food ingredient. What are the most significant dietary sources of fructose? Fructose is also found in sucrose (table sugar), honey, agave nectar, fruit juices, fruit juice concentrates, pure crystalline fructose and high fructose corn syrup (HFCS). Functionality & Use What are the primary foods and beverages in which fructose is used? Why has the production of fructose Primary applications for crystalline risen in the past 30 years? fructose include dry mix beverages, For one simple reason: fructose low calorie products, enhanced or is a high quality ingredient with flavored water, still and carbonated many useful physical and functional beverages, sports and energy drinks, properties.

Limiting fructose or HFCS in the diet would not have an impact on global obesity.

Further, obesity is a global phenomenon while HFCS is primarily used in the United States. Obesity rates in Europe and South America are high whereas these areas do not use HFCS as a sweetening agent for food and beverages..

    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.

How do glucose levels Research in different drinks change after adding Question an invertase enzyme? Given that the invertase enzyme breaks down sucrose, glucose levels will rise after adding the enzyme because the sucrose will convert to Hypothesis glucose and fructose. Coca Cola will have the most glucose because it has the most calories of each drink. Glucose - Chemical compound in the body - C6H12O6 - Comes from food and drink - Generally rich in sugars/carbohydrates - Used for many purposes: - Used to make energy (ATP) in cellular respiration - Stores energy - Used to build carbohydrates Chemical Reaction - A chemical reaction transfers a set of compounds into another - Reactants: Enter into a chemical reaction - Products: Compounds produced by the reaction - Catalyst: Speeds up the rate of a chemical reaction - Enzyme: Biological catalysts; usually proteins The formula for this experiment is: Invertase Sucrose + Water Glucose + Fructose Invertase C12H22O11 + H20 C6H12O6 + C6H12O6 In the Body - The most common sugar is eaten as sucrose. - Also known as table sugar - It is broken down in the body into glucose and fructose through a chemical reaction during digestion. - Fructose: Contains the same elements as glucose, but has a different chemical construction - Often used to make more glucose - The reaction is catalyzed by an enzyme named sucrase. - Modeled by invertase in experiment - The pancreas monitors blood sugar, or amount of glucose in the body.

  • GRAINS of TRUTH for DIABETES by Jeanne Brown, RD,CDE, LD
    GRAINS OF TRUTH FOR DIABETES By Jeanne Brown, RD,CDE, LD Avoiding pasta to lower your blood sugar? Wondering how to identify whole grains? Does the glycemic index (GI) of grains matter? Here are some grains of truth for diabetes. Whole grains provide fiber, vitamins, minerals, antioxidants and in general have a lower GI which reduces the risk of diabetes. Researchers have found a 30 % lower risk of diabetes with high fiber diets from grains. People who eat at least 2 servings per week of brown rice have a 11% lower risk of Type 2 Diabetes than those that eat less. The risk of getting Type 2 Diabetes was 2 ½ times greater for people who had the highest glycemic load and lowest fiber intake in the study. The GI measures how a carbohydrate- containing food raises blood sugar. The GI ranges from 0 to 100. The higher the number, the more likely it will raise blood sugars. The GI is also affected by how the food is processed, how it is cooked and the ripeness of fruit. Pasta cooked just until it is firm and chewy has a lower GI than overcooked pasta. A ripe banana will spike blood sugar more than an unripe banana. Tips: Look for the word “WHOLE” grain. “Whole” ensures they used the entire grain which includes the fiberous bran, and nutrient dense germ. “Wheat bread” or “wheat flour” is not necessarily whole grain unless it states “whole wheat" in the beginning of the ingredient list. Products such as: 100% whole wheat bread, shredded wheat cereal and Triscuit crackers are 100 % whole grains.

  • Effect of Glycemic Index and Glycemic Load on Type 2 Diabetes Mellitus
    International Journal of Health Sciences and Research www.ijhsr.org ISSN: 2249-9571 Review Article Effect of Glycemic Index and Glycemic Load on Type 2 Diabetes Mellitus Towhid Hasan1, Marjia Sultana1, Lincon Chandra Shill1, Nafisa Habib Purba1, Sara Sultana2 1Department of Food Technology and Nutrition Science, Noakhali Science and Technology University, Noakhali-3814, Bangladesh 2Department of Pharmacy, University of Dhaka, Dhaka-1000, Bangladesh Corresponding Author: Marjia Sultana ABSTRACT Worldwide diabetes mellitus especially type 2 diabetes mellitus (T2DM) has become a common and rapidly growing chronic non-communicable disease with potentially devastating complications, posing major public health and socioeconomic challenges. The role of glycemic index (GI) and glycemic load (GL) in the control of the T2DM remain controversial. However, a number of mechanisms have been proposed through which dietary GI and/or GL can reduce the risk of T2DM, but all are suggestive. So, the present review is aimed to investigate the current understanding of the effect of GI and/or GL on the risk of T2DM.PubMed, Google Scholar, Cochrane library and several other databases were searched up to December 2018 to identify and select relevant studies. Research conducted using human are only considered eligible. Among the eighteen prospective cohort studies, eight have found no significant association of dietary GI and/or GL with T2DM risk, six studies revealed an association and four studies identified positive association only with GI but not with the GL. Among the ten interventional studies, only two indicated that the risk of T2DM increased with the increment of GI and GL. In conclusion, research on the glycemic response of foods needs to be expanded in order to get a broad and clear knowledge which will provide assurance that how dietary GI and/or GL have play role on the risk of T2DM.

  • Sugar Checklist
    ! All sugars are not created equally. Natural sweeteners like honey, agave, or cane sugar are not any better for you than "other" sugars. There is a widespread belief that "natural" is better - and that natural things can't be bad for you. Sugar is one of those very wrong assumptions. Many, many times I've heard people in the supermarket remark that agave or honey is better for you because they're "natural" sugars. But is it true?. Your Body On Sugar: Natural Sweeteners 101 Glucose is the main energy source of your body. Your brain requires glucose to function, and in fact, a huge percentage of your daily calories go to powering your brain. Pretty cool huh? So there's glucose - the "sugar" in your blood that gives you energy. Your body generally gets it from eating carbohydrates (although the body can make it from other sources if it has to). Then there's dextrose - glucose produced from plant sources (like corn). Then you've got fructose - fructose is the form of sugar generally found in fruits and honey. (Think F = Fruits) Then there's sucrose, which is half glucose, half fructose - following me? Sucrose is table sugar, the white grainy stuff you usually associate with being sugar. So here are the general rules: Glucose = from carbs. Fructose = from fruits, honey, agave, and high fructose corn syrup. Dextrose = usually produced commercially then added to food to sweeten it. Sucrose = white table sugar, produced from the sugar cane plant (& other sources). Natural Is Better Is Not Better - The Truth Behind Brown Sugar, White Sugar, Raw Sugar, Agave, Honey, High Fructose Corn Syrup ! Sugar in its varying processing phases: White refined, unrefined, brown, unprocessed People mistakenly have the idea that natural sweeteners and natural sugars are somehow different from "other" sugars, so they go ahead and load up on raw cane sugar, honey, or agave and aren't worried about dumping it in everything they drink or eat.

  • 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.

  • Matthew Przybysz
    Matthew Przybysz Bio Lab Report 11/18/12 OBJECTIVE: The objective of this lab was to determine if LACTAID really works to digest milk sugar, lactose. If lactaid is added to milk, glucose will be detected because lactaid contains lactase, which breaks down the lactose in milk. The dependent variable in this lab was the type of reaction (positive or negative) and the independent variable was the type of liquid, which included lactaid, glucose, milk, water, and lactaid and milk combined. INTRODUCTION: Lactaid is a product that you can purchase in a regular store and it contains lactase. Therefore people who are lactose intolerant can have milk products. Regular dairy products contain lactose. In order for lactose to be broken down, our bodies contain an enzyme called lactase. Enzymes are biomolecules that catalyze chemical reactions. An enzyme doesn’t supply activation energy to the reacting molecules, but instead lowers the energy requirement barrier so that the reaction can proceed at normal cell temperatures. (1) Almost all enzymes are proteins. Like all catalysts, enzymes work by lowering the activation energy for a reaction, thus dramatically increasing the rate of the reaction. (1, 2) A substrate is a specific reactant acted upon by an enzyme. The enzyme breaks the bond of the molecule substrate. In this lab experiment the substrate was lactose. Lactase broke apart the substrate lactose into two different sugar molecules called glucose and galactose. An enzyme substrate complex is a non-covalent complex composed of a substrate bound to the active site of the enzyme. The enzyme takes in substrates to the active zone of the enzyme.(2) The substrates then interact with each other and form new products, and they are released.

  • Get Off the Blood Glucose Roller Coaster Avoid the Glucose Highs and Lows That Affect Your Thinking and Mood
    Get Off the Blood Glucose Roller Coaster Avoid the glucose highs and lows that affect your thinking and mood. Extreme blood sugar highs and lows can lead to major problems. There are physical symptoms; you are more likely to get long term problems from diabetes as well. Often, there are signs that your blood sugar is off target. Among the first signs are changes in your thinking and mood. Learn to spot and act on the warning signs. This will help you get off the blood sugar roller coaster. The goal is to keep your blood sugar and your mood as stable as you can. Symptoms of low blood sugar (hypoglycemia) When blood sugar drops below the normal range (70-120 mg/dL), you can start to feel signs. You may sweat, get a fast heart beat, and feel jittery. Blood sugar will go lower if you don't take action. Eat or drink something that has sugar. If blood sugar goes lower, things can get worse very fast; you can have confusion, loss of consciousness, or coma. Alice is a patient of mine. She had a recent bout of low blood sugar in the middle of the night. She made it to the kitchen. She knew she needed a snack. She went to the refrigerator and she opened the door; Alice then stood there for 15 minutes. She was trying to decide which juice she should drink to raise her blood sugar. This is how low blood sugar, in its early stage, can affect thinking. Her trouble with being able to make a simple choice like this is common.
