WebRing 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 … WebD-glucose, blood sugar, exists in two forms; ring open and ring closed. Don't worry about the chemistry of ring closure (but FYI, arrows are pointing at the atoms involved in this cyclization). This is an example of a problem that has all kinds of irrelevant information that you have to ignore as you search for the actual question.

WebSep 12, 2024 · Ring Structure for Fructose Since fructose has a ketone functional group, the ring closure occurs at carbon # 2. 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 a 5 member ring – four carbons and one oxygen. http://chemistry.elmhurst.edu/vchembook/543glucose.html WebThe glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form.
