Pyranoses and Furanoses Bio chem question

[exacto]

---

Members don't see this ad.

Can aldehydes and ketones ( hexoses and pentoses) both become pyranoses and furanoses?

It looks like only aldehhexoses such as glucose can form pyransose rings and only ketohexoses such as fructose can form furanose rings?Am i correct?

Or what sugars can form into the 5 or 6 member rings???

Aldoses and ketoses, both pentose and hexose, can all form both pyranoses and furanoses. One form will be more favored at equilibrium depending on the sugar.
