What Is the Difference Between Sucrose, Glucose & Fructose? | Healthy Eating | SF Gate
FINAL EXAM - Answer Key March 19, Identify the relationship between each pair of compounds: (either constitutional isomers, diastereomers, enantiomers, D-glucose and D-fructose are -- constitutional isomers. D- galactose and. Not all sugars are created equal, which matters when it comes to your health. Here's the difference between sucrose, glucose and fructose. The Sucrose/D-Fructose/D-Glucose test kit is suitable for the measurement and analysis of sucrose, D-glucose and D-fructose in plant and food products. D-Glucose Assay Kit (GOPOD Format) UV-method for the determination of Sucrose, D-Fructose and.
Image modified from OpenStax Biology. As shown in the figure above, every other glucose monomer in the chain is flipped over in relation to its neighbors, and this results in long, straight, non-helical chains of cellulose. This gives cellulose its rigidity and high tensile strength, which are important to plant cells.
However, some herbivores, such as cows, koalas, buffalos, and horses, have specialized microbes that help them process cellulose. These microbes live in the digestive tract and break cellulose down into glucose monomers that can be used by the animal.
Wood-chewing termites also break down cellulose with the help of microorganisms that live in their guts. Image of a bee.

The bee's exoskeleton hard outer shell contains chitin, which is made out of modified glucose units that have a nitrogenous functional group attached to them. Cellulose is specific to plants, but polysaccharides also play an important structural role in non-plant species. For instance, arthropods such as insects and crustaceans have a hard external skeleton, called the exoskeleton, which protects their softer internal body parts.
This exoskeleton is made of the macromolecule chitin, which resembles cellulose but is made out of modified glucose units that bear a nitrogen-containing functional group.
Chitin is also a major component of the cell walls of fungi, which are neither animals nor plants but form a kingdom of their own. Download the original article for free at http: Sucrose is the scientific name for table sugar.
Sugars are categorized as monosaccharides or disaccharides. Disaccharides are made up of two, linked monosaccharides and broken back down into the latter during digestion 1. Table sugar and the sucrose found in processed foods are commonly extracted from sugar cane or sugar beets.
Sucrose tastes less sweet than fructose but sweeter than glucose 2. Glucose Glucose is a simple sugar or monosaccharide. Monosaccharides are made up of one single unit of sugar and thus cannot be broken down into simpler compounds. In foods, glucose is most commonly bound to another simple sugar to form either polysaccharide starches or disaccharides, such as sucrose and lactose 1.
Glucose is less sweet than fructose and sucrose 2. Fructose is sourced from sugar cane, sugar beets and corn.
High-fructose corn syrup is made from cornstarch and contains more fructose than glucose, compared to regular corn syrup 3. Of the three sugars, fructose has the sweetest taste but least impact on your blood sugar 2.
Summary Sucrose is made up of the simple sugars glucose and fructose. Sucrose, glucose and fructose are found naturally in many foods but also added to processed products. On the other hand, disaccharides like sucrose must be broken down into simple sugars before they can be absorbed.
Glucose Absorption and Use Glucose is absorbed directly across the lining of the small intestine into your bloodstream, which delivers it to your cells 45. It raises blood sugar more quickly than other sugars, which stimulates the release of insulin 6.
Insulin is needed for glucose to enter your cells 7. Once inside your cells, glucose is either used immediately to create energy or turned into glycogen to be stored in your muscles or liver for future use 89. Your body tightly controls your blood sugar levels. When they get too low, glycogen is broken down into glucose and released into your blood to be used for energy 9. If glucose is unavailable, your liver can make this type of sugar from other fuel sources 9.
Fructose Absorption and Use Like glucose, fructose is absorbed directly into your bloodstream from the small intestine 45. It raises blood sugar levels more gradually than glucose and does not appear to immediately impact insulin levels 6 Your liver has to convert fructose into glucose before your body can use it for energy. If you eat more fructose than your liver can handle, the excess is turned into cholesterol and triglycerides This may have negative health effects such as obesity, fatty liver disease and high cholesterol.
D and L Sugars
Sucrose Absorption and Use Since sucrose is a disaccharide, it must be broken down before your body can use it. Enzymes in your mouth partially break down sucrose into glucose and fructose, and acid in your stomach breaks it down further.
However, the majority of sugar digestion happens in the small intestine 4. The enzyme sucrase, which is made by the lining of your small intestine, splits sucrose into glucose and fructose.
