How are glucose and fructose similar?
Both fructose and glucose are monosaccharides , have the same caloric values (roughly 4Cal/g), and the same molecular formula of CC6H1206. Differences between glucose and fructose Fructose: is poorly absorbed and can cause fructose intolerance. It is moved to the colon, where it undergoes fermentation by bacteria producing gas, bloating and diarrhea. Glucose: is well absorbed. Brain interaction (4) Fructose: is slowly up taken through the brain barrier, causing the reduction of neural activity. Glucose: is up taken quickly to the brain barrier where it is metabolised using most of the oxygen available in the brain. Glucose raises the level of neural activity for about 20 minutes after its consumption. Fructose: is mainly (but not exclusively) metabolised by the liver. Other cells that accept fructose (although to a much lesser extent) are testicles, kidneys, skeletal muscles, fat tissue and brain. Fructose is up taken to the cells via a transporter called GLUT5 and also via GLUT2, to a smaller extent, which accepts fructose to the liver cells. Glucose: is up taken to most of the cells in the body for metabolism. It uses the following transporters to distribute glucose to corresponding cells: GLUT1 (to all cells), GLUT2 (to gut, liver and pancreas), GLUT3 (to central nervous system and brain), GLUT4 (to cells that need insulin to be up-taken such as skeletal muscles, fatty tissue and heart). Diabetics risk (7) Fructose: presents a long term risk for diabetics. Fructose only slightly increases blood glucose levels and insulin p Continue reading >>
What are carbohydrates made of?
Carbo, refers to carbon and hydra, comes from the word water. So, you can think of carbohydrates as carbon plus water. Carbohydrates are compounds made up of carbon, hydrogen, and oxygen atoms. In carbohydrates, the elements carbon, hydrogen, and oxygen are usually found in the ration of 1:2:1. Carbohydrates have the general chemical formula of CH2O. There are two main classes of carbohydrates: simple sugars and complex carbohydrates. The monomer of a carbohydrate is a monosaccharide . Monosaccharides include glucose, fructose, and galactose. Notice that each of these end in the Latin suffix ose. The suffix means full of and is used in chemistry when naming sugars. The structures of glucose, fructose, and galactose are shown below. Under each structure is the chemical formula of the compound. Source: Glucose, galactose and fructose, Food Science and Technology If you look closely at the molecular formulas, you will notice they are all the same. Glucose, fructose, and galactose are what chemists refer to as isomers. Isomers have the same chemical formula, but the atoms in the molecule are attached differently. You know that glucose is a product of photosynthesis. Glucose is often referred to as blood sugar because it is the immediate source of energy during cellular respiration. All carbohydrates are broken down into glucose for transport via the bloodstream and used by the cells of the body. Galactose is the sugar in milk and yogurt while fructose is a sugar commonly found in fruit. What about table sugar? What type of sugar is Continue reading >>
What are the two common carbohydrates?
However, the arrangement of atoms in carbohydrates has little to do with water molecules. Starch and cellulose are two common carbohydrates. Both are macromolecules with molecular weights in the hundreds of thousands. Both are polymers (hence "polysaccharides"); that is, each is built from repeating units, monomers, much as a chain is built from its links. The monomers of both starch and cellulose are the same: units of the sugar glucose. Sugars Monosaccharides Three common sugars share the same molecular formula: CHO. Because of their six carbon atoms, each is a hexose. They are: glucose, "blood sugar", the immediate source of energy for cellular respiration galactose, a sugar in milk (and yogurt), and fructose, a sugar found in honey. Although all three share the same molecular formula (C6H12O6), the arrangement of atoms differs in each case. Substances such as these three, which have identical molecular formulas but different structural formulas, are known as structural isomers. Glucose, galactose, and fructose are "single" sugars or monosaccharides. Two monosaccharides can be linked together to form a "double" sugar or disaccharide. Disaccharides Three common disaccharides: sucrose — common table sugar = glucose + fructose lactose — major sugar in milk = glucose + galactose maltose — product of starch digestion = glucose + glucose Although the process of linking the two monomers is rather complex, the end result in each case is the loss of a hydrogen atom (H) from one of the monosaccharides and a hydroxyl group (OH) from the other. The resulting linkage between the sugars is called a glycosidic bond. The molecular formula of each of these disacchar Continue reading >>
What are the three elements that make up carbohydrates?
Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose). Carbohydrates are: a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants building blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATP Monosaccharides Monosaccharides are the simplest carbohydrates and are often called single sugars. They are the building blocks from which all bigger carbohydrates are made. Monosaccharides have the general molecular formula (CH2O)n, where n can be 3, 5 or 6. They can be classified according to the number of carbon atoms in a molecule: n = 3 trioses, e.g. glyceraldehyde n = 5 pentoses, e.g. ribose and deoxyribose ('pent' indicates 5) n = 6 hexoses, e.g. fructose, glucose and galactose ('hex' indicates 6) There is more than one molecule with the molecular formula C5H10O5 and more than one with the molecular formula C6H12O6. Molecules that have the same molecular formula but different structural formulae are called structural isomers. Glyceraldehyde's molecular formula is C3H6O3. Its structural formula shows it contains an aldehyde group (-CHO) and two hydroxyl groups (-OH). The presence of an aldehyde group means that glyceraldehyde can also be classified as an aldose. It is a reducing sugar and gives a positive test with Benedict's reagent. CH2OHCH (OH)CHO is oxidised by Benedict's reagent to CH2OHCH (OH)COOH; the aldehyde group is oxidised to Continue reading >>
Is sucrose a simple sugar?
Glucose and fructose have the same molecular formula (C6H12O6) but glucose has a six member ring and fructose has a five member ring structure. Fructose is known as the fruit sugar as its make source in the diet is fruits and vegetables. Honey is also a good source. Glucose is known as grape sugar, blood sugar or corn sugar as these are its riches sources. Listed in food ingredients as dextrose. Sucrose is the sugar we know as sugar or table sugar. Typically extracted as cane or beet sugar. If sucrose is treated with acid or heat, it hydrolyzes to form glucose and fructose. This mixture of sucrose, glucose and fructose is also called invert sugar. Nutritionally, these sugars are the same as they all provide 4 Cal/g. This is true for starch and other digestible carbohydrates too. Of the three sugars, fructose is the sweetest and glucose the least sweet, so typically less fructose can be used than table sugar (sucrose) – if sucrose has a sweetness of one, fructose is 1.7 and glucose 0.74 Fructose is more soluble than other sugars and hard to crystallize because it is more hygroscopic and holds onto water stronger than the others. This means that fructose can be used to extend the shelf life of baked products more than other sugars. Wikipedia has lots information on sugars, including information on the three I am interested in fructose, glucose and sucrose. Continue reading >>
Is fructose the same as glucose?
While fructose and glucose have the same calorific value, the two sugars are metabolized differently in the body. Fructose has a lower glycemic index than glucose but has a much higher glycemic load.

What is the difference between fructose, lactose, maltose, and sucrose?
Difference between Fructose, Glucose, Lactose, Maltose and Sucrose Key Difference:Glucose and Fructose are monosaccharides, whereas Lactose, Maltose and Sucrose are disaccharides. Glucose is classified as an aldehyde, whereas fructose as a ketone. Two glucose units are combined to form Maltose. Sucrose is formed by combination of Fructose and Glucose. Lactose consists of Galactose and Glucose. Carbohydrates play a vital role as they provide energy to cells in the body. Dietary carbohydrates can be broadly classified into various categories based on the number of sugar units present in them. Monosaccharide consists of one sugar unit, whereas Disaccharide consists of two sugar units. Glucose and Fructose fall in the category of monosaccharide, whereas Sucrose, Lactose and Maltose are types of Disaccharide. Monosaccharides are known as building blocks from which all other big carbohydrates are made. Glucose and Fructose are common sugars and possess the same molecular formula : C6H12O6.They contain six atoms of carbon and therefore are also known to be a hexose. Glucose is the blood sugar. It is also known as glucose, dextrose or grape sugar. Glucose and Fructose possess the same molecular formula. However, they differ in the arrangements of atoms in their structure and therefore are also termed as structural isomers of each other. Fructose is found in fruit, honey, etc. Glucose is an aldehyde which means that it a compound which contains a carbonyl group with at least one hydrogen attached to it. On the other hand, fructose is a ketone, which means that it is a compound which contains a carbonyl group with two hydrocarbon groups attached to it. Lactose is made from the combination of galactose and glucose units. It is the major carbohydrate which is found in milk. D-gluc Continue reading >>
What is the difference between glucose and galactose?
Categorized under Nature , Science | Difference Between Glucose and Galactose Although the molecular formula of glucose and galactose are identical, they have distinct structural formulas. Glucose is a simple sugar (monosaccharide) and also termed as blood sugar, grape sugar or corn sugar. It is a vital carbohydrate in biology. It is a premium source of energy for the living cells and also acts as a metabolic intermediate. It is among the chief products extorted from the process of photosynthesis. On the other hand, galactose also comes under the family of monosaccharide and it is a type of sugar that is less sweet in comparison to glucose. It consists of food energy (expressed in calories or joules) and termed as nutritive sweetener. There are only two stereoisomers actually known as glucose in the category of aldohexose sugars. In these two stereoisomers, only dextrose monohydrate (commonly known as D-glucose) is organically active. In contrast, there is polymer of sugar galactose called galactan. It exists in the body to maintain the supply of galactose. It is stored inside the body in bulk form at a place called hemicellulose. Whenever there will be an additional requirement of galactose than the process of hydrolysis takes place and galactan is eventually converted into galactose. Coming back to glucose, besides D-glucose there is one more glucose, which is biologically inactive. The inactive form of glucose is termed as L-glucose. It is not possible to metabolize the molecules of L-glucose by the process called glycolysis. Glucose and galactose are also synthesized by the body. However, the external sources will vary from each other. Glucose can be divided into two types: simple carbohydrate and complex carbohydrate. Simple carbohydrates easily get to digest and Continue reading >>
What are the three types of monosaccharides?
the simplest, complete type of carbohydrate molecule 3. When mixed with water, monosaccharides typically form ring-structures Glucose, fructose, and galactose are 3 common types of monosaccharides that living cells use for energy; each has the molecular formula of C6H12O6 What makes one different from the other is the way the individual atoms bond into position in each molecule; giving each molecule its own shape of structural formula Molecules with the same molecular formula, yet different structural formulas, are known as structural isomers Monosaccharides can combine with other monosaccharides during synthesis reactions to produce another class of carbohydrates, the disaccharides 1. Disaccharides are sometimes preferred to as the processed sugars because they are added to many prepackaged foods 2. Since disaccharides are larger than monosaccharides, they are a type of intermediate or transition to polymer 3. Disaccharides contain more chemical energy than monosaccharides 4. Since so many foods contain disaccharides people often ingest too much energy per day. The calories they are not burning off are treated as empty calories by the body and stored for later use 5. If/when disaccharides are bonded to increasingly more monosaccharides, via dehydration synthesis, the third class of carbohydrates is called the polysaccharides 1. These are the largest polymers in the carbohydrate group of organic nutrients 2. They are composed of hundreds to thousands of monosaccharides bonded together by a chain reaction of dehydration synthesis 3. In the human body, glycogen, produced by the liver and skeletal muscles, and dietary fiber are examples if polysaccharides 4. They act as a reserve for monosaccharides to slightly extend how long Continue reading >>
