It is made on industrial scale by treating pentose with heat and a strong acid (like sulfuric acid). This leads to formation of furane-2-carbaldehyde. The aldehyde can be removed by reaction with zinc oxide @ 400 degrees C, giving unsubstituted furan.
Hi I m confused that in simple furan why it do not show nucleophilic subtitution reaction. while in subtituted furan show it.
furan though has a lone pair of electron which is not delocalised but due to high electronegetivity of oxygen it is not a available for donation hence has weak basic proerty
Pentose is a five carbon sugar. They make up the sugars that form DNA and RNA.
No. It is an aldehyde. Furfural is furan-2-carboxaldehyde.
pentose phosphate pathway (also called phosphogluconate pathway, or hexose monophosphate shunt [HMP shunt])

DNA contains the pentose sugar deoxyribose where as RNA contains the pentose sugar ribose.

No, oil does not contain pentose properties. Pentose is a monosaccharide that has 5 different carbon atoms and they are usually organized into 2 different groups.
The pentose phosphate pathway occurs in the cytosol of cells.
Deoxyribose, the "D" of DNA, is indeed a pentose.
Because it has 2 double bonds. An ether might not have any double or triple bonds!
