Pyranose and furanose form of D-Fructose

[@Al0lyy]

Thank you, it was very helpful

[@nellymunyoto387]

Well explained..thank you very much

Thaanku for learning 🙂

Thank you

The beta-D-fructopyranose was misslabeled as fructofuranose, it‘s a 6-membered ring, not 5-membered

Youre right! I was Confused, thanks

Tq so much mam

But I think fructose has 5membered ring and please don't do videos on unknown content
Many students who are confused watch the videos please don't confuse then by making false content

Thanku for watching the full video and giving an opportunity to explain this content which will be helpful to others as well.
Fructose can have 2 isomeric forms pyranose and furanose depending on which OH group is involved. When fructose is dissolved all the 4 anomers of fructose i.e alpha, beta furanose n pyranose exists. Depending on temperature the percentage changes. So all four are possible.
Now it depends from where u are reading the content. The beta D fructopyranose infact forms 68% at 25 degree celcius. In few biochemistry books the furanose form is given as the last OH is phosphate metabolite which is not available for ring formation.
In reference books the all forms of furanose are mentioned.
Hence i am not teaching or preaching anything wrong, not i m putting any kind of false content.
The video is about how to draw the structures.
U can refer some reference books and do some literature work regarding the same and then we can discuss this. So what you think is not important what actually is there is more relevant.
Once again thanku for watching the video.
