Explanation:
The d-isomer, d-glucose, also known as dextrose, is commonly found in nature, but the l-isomer, l-glucose, is not. Hydrolysis of carbohydrates such as dairy sugar (lactose), plant sugar (sacrose), maltose, cellulose, glycoGlucose 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. They differ in the nature of the functional groupgen, etc. can be used to obtain glucose.Both Glucose and Fructose are hexose sugars with six carbon atoms but Glucose is an aldohexose and fructose is ketohexose which means the functional group present in glucose is an aldehyde and the functional group in fructose is a ketone.

9 thoughts on “4 Simple Steps – Chain Glucose Molecule”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.
Keto-D-fructose is the open-chain form of D-fructose. It is a keto-fructose and a D-fructose.
it is called STRUCTURE OF GLUCOSE AND FRUCTOSE
Glucose:
The most abundant monosaccharide found in nature is in fact glucose. It is the most abundant organic compound on earth. We can find glucose in varies fruits, honey and even in starch and cane sugar. We obtain a large part of the energy in our bodies from glucose through the foods we eat. It is an aldohexose, which means it has six carbon atoms in its molecule. Its chemical formula is C6H12O6
We obtain glucose mainly from two sources which are starch and sucrose. Let us look at how we can prepare glucose from these sources
Fructose:
Fructose is a simple ketonic monosaccharide. We mostly find fructose in plants and their fruits, flowers and root vegetables, hence earning it a moniker of fruit sugar. It is also abundantly present in honey and corn syrup. Generally, fructose bonds with glucose to form a disaccharide we know as sucrose. Fructose was first discovered by a French chemist Augustin – Pierre Debrunfaut.
The chemical formula of fructose is also C6H12O6 but the bonding of fructose is very different than that of glucose. Fructose has a cyclic structure. The structure is an intramolecular hemiacetal. It has its carbonyl group at its number two carbon (its a ketone function group). In its cyclic form, it (generally) forms a five-member ring which we call a Furanose ring.
