Why can glucose and fructose have the same chemical formula but have two different names?
Although glucose, galactose, and fructose all have the same chemical formula (C6H12O6), they differ structurally and chemically (and are known as isomers) because of the different arrangement of functional groups around the asymmetric carbon; all of these monosaccharides have more than one asymmetric carbon (Figure3.2.
What is the difference between glucose and fructose chemical formula?
Glucose and fructose are simple sugars. Simple carbohydrates are classified into two types. They are monosaccharide and disaccharide. Monosaccharides are made of one sugar unit and are the most basic form of sugar….Fructose.

Why is the molecular formula of glucose and fructose same?
Glucose and fructose are functional isomers of each other because they have same molecular formula that is C6H12O6 But different functional group in their chemical formula. Glucose has aldehyde group while fructose has ketone as functional group.
How are fructose and glucose different from one another?
Glucose is sourced by breaking down disaccharides or polysaccharides, which are larger sugar molecules. Meanwhile, fructose is found in its simplest form in fruits and some vegetables like beets, corn and potatoes.” Like all sugars, both glucose and fructose are carbohydrates. But not all carbs are created equal!
How do glucose fructose and galactose similar what makes them different?
Glucose and galactose are stereoisomers (have atoms bonded together in the same order, but differently arranged in space). They differ in their stereochemistry at carbon 4. Fructose is a structural isomer of glucose and galactose (has the same atoms, but bonded together in a different order).
Does glucose and fructose have the same empirical formula?
So, glucose and fructose have the same empirical formula too: CH2O. The reason that glucose and fructose have the same molecular and empirical formulas despite being different compounds is that they are isomers.
Are glucose and fructose tautomers?
– Glucose, mannose, and fructose, all belong to the D series and they are easily interconvertible through their keto-enol tautomerism and these relation is represented below, – Thus D-glucose, D-mannose and D- fructose are enol forms of the given compound (fructose).
What are the structural similarities and differences between glucose and fructose?
Glucose is an aldehyde and whereas fructose is a ketone and has following structure according to Fischer projections. Another difference is the number of chiral carbons in glucose is 4 whereas in fructose is 3. Also the number of 2° alcohol is 4 for glucose and 3 for fructose.
How are fructose and glucose different from one another quizlet?
Glucose and fructose are structural isomers: have the same chemical formula but have different arrangement of atoms. While glucose has aldose sugar- carbonyl group at the end of the chain, fructose has ketose sugar- carbonyl group in an internal of the chain (specifically, at the second carbon.
Why do glucose galactose and fructose have the same properties?
Glucose, galactose, and fructose are monosaccharide isomers, which means they all have the same chemical formula but differ structurally and chemically. Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond.
How are glucose and fructose chemically related?
What are the similarities and differences between fructose and glucose?
1.Fructose and glucose are both monosaccharides with the same chemical composition but a different molecular structure. 2.These two sugars are found in some combination in nearly all sweetened foods available. 3.Glucose needs insulin for proper metabolizing while fructose needs no insulin to be processed.
What are the different types of sugar?
Sucrose, glucose and fructose are important carbohydrates, commonly referred to as simple sugars. Sugar is found naturally in whole foods and is often added to processed foods to sweeten them and increase flavor. Your tongue can’t quite distinguish between these sugars, but your body can tell the difference.
What is the chemical formula for fructose?
Fructose Properties Fructose Formula C 6 H 12 O 6 Fructose Molar mass 180.156 g/mol Fructose Chemical Formula C 6 H 12 O 6 Density 1.694 g/cm 3 Melting point 103°C
What is the difference between simple sugar and sucrose?
Simple sugars contain only one type of carbohydrate as opposed to two like the disaccharide sucrose. The chemical formula for glucose and fructose are also the same: C6(H2O)6. Once they have entered the body, both sugars eventually make their way to the liver to be metabolized.
