Which functional group is present in fructose?
Answer: Fructose has a ketone functional group. Glucose has aldehyde and hydroxy functional group.
How many functional groups are in fructose?
This basic structure accounts for two of the four functional groups. Turning to another basic saccharide, fructose, we can identify a ketone functional group, as shown in the figure below. Here, because the C=O. bond is bridged by two carbons instead of one carbon and one hydrogen, it is a ketone functional group.
What is fructose function?
One of the major biological functions of fructose is it acts as an alternative metabolite in providing energy especially when glucose is not sufficient while the metabolic energy demand is high. It can enter glycolysis and produce intermediates for cellular respiration.
What are the functional groups of sugars?
Carbonyl and hydroxyl are the two main functional groups of sugars. The carbonyl and hydroxyl group present in all sugars. They are the basic components of sugars. Sugars are basically a carbohydrate and they are polyhydroxy aldehyde, ketone and their derivatives.
Is fructose a carbonyl group?
In fructose, the carbonyl group is on the C2 carbon, forming a ketone group. The former sugars are called aldoses based on the aldehyde group that is formed; the latter is designated as a ketose based on the ketone group.
What are the functional group present in glucose and fructose?
In glucose we have five alcohol groups (−OH) and one aldehyde group (R−H|C=O). In fructose also we have five alcohol groups but one ketone group (R−R|C=O), where R group is a chain of carbon atoms or one carbon atom. Therefore, the common functional group in Glucose and Fructose is alcohol group, −OH.
How many carbons are in fructose?
6 carbons
Fructose is another sugar that also has 6 carbons, 12 hydrogens, and 6 oxygen atoms. However, the arrangement of the atoms is different, and this makes it much sweeter than glucose and also affects its ability to combine with other molecules.
What is the structure and function of fructose?
Fructose, or fruit sugar, is a simple ketonic monosaccharide found in many plants, where glucose is often bonded to form the sucrose disaccharide. As well as glucose and galactose, it is one of the three dietary monosaccharides that are absorbed directly into the blood during digestion.
What are the functions of glucose and fructose?
Glucose is used for energy or stored as glycogen. Fructose is converted to glucose or stored as fat.
What functional groups are present in glucose fructose and galactose?
In glucose and galactose, the carbonyl group is on the C1 carbon, forming an aldehyde group. In fructose, the carbonyl group is on the C2 carbon, forming a ketone group. The former sugars are called aldoses based on the aldehyde group that is formed; the latter is designated as a ketose based on the ketone group.
Does fructose have an aldehyde group?
Characteristics of Reducing Sugars The reducing sugars such as glucose and fructose have a free aldehyde group and ketone in their structures, respectively.
What type of compound is fructose?
Fructose is a carbohydrate, an organic compound in which five of the six carbon atoms are arranged in a ring to which are attached the hydrogen atoms and hydroxy (−OH) groups that make up the molecule.
