ring structure of fructose

Pyranose

Pyranose is a collective term for saccharides that have a chemical structure that includes a six-membered ring consisting of five carbon atoms and one oxygen atom There may be other carbons external to the ring The name derives from its similarity to the oxygen heterocycle pyran but the pyranose ring does not have double bonds A pyranose in which the anomeric OH at C(l) has been

Structure Function of Sucrose

Unique Structure All sugars are made from three basic building blocks -- carbon hydrogen and oxygen -- connected to form different structures Sucrose consists of one molecule of glucose connected to one molecule of fructose The connection between the molecules called an acetal oxygen bridge makes sucrose a non-reducing sugar which means it's less reactive than most other sugars This

In contrast sugars dissolved in a solution such as the fluid of a cell's interior frequently convert into a "ring" structure The molecular formula of a sugar is not affected by conversions from a long chain to a ring structure The ring forms of sugars are the structures that

Carbohydrates: Types of Carbohydrates

Fructose is a structural isomer of glucose meaning it has the same chemical ormula but a completely different three-dimensional structure The main difference is that fructose is a ketone in its linear form while glucose is an aldehyde Through an intramolecular addition reaction with the C-5 OH group glucose forms a six-membered ring while fructose forms a five-membered ring as seen in

Ring Structure for Fructose: The chair form of fructose follows a similar pattern as that for glucose with a few exceptions Since fructose has a ketone functional group the ring closure occurs at carbon # 2 See the graphic on the left In the case of fructose a five membered ring is formed The -OH on carbon #5 is converted into the ether linkage to close the ring with carbon #2 This makes

The Fructose molecule in 3

Fructose (fruit sugar) is a monosaccharide - formula C 6 H 12 O 6 It shares the same empirical formula with other 6-carbon (hexose) sugars such as glucose and galactose 6 carbon atoms (grey) form the backbone of the molecule and in this version of the fructose molecule the middle 4 carbons form into a 5 sided ring with one oxygen atom (red) in the ring Label / unlabel Carbon numbers The

Properties Of Monosaccharides

Fructose has a cyclic structure Fructose is a simple ketonic monosaccharide Due to the presence of the keto group it results in the formation of intramolecular hemiacetal In this arrangement C5-OH combines with the ketonic group present in the second position This results in the formation of chiral carbon and two arrangements of CH2OH and OH group Hence D-fructose exhibits
