How many c-atoms are there is a pyranose ring

WebYou are forming a carbon ring, and a 6-membered ring has the most stable bond angle, which is why you have C1-C2-C3-C4-C5-O as your ring structure. Btw, 5 membered rings also occur naturally (see: ribose) but they are simply not as stable. And if 6 is possible, why settle for 5? :-) 3 comments ( 7 votes) Show more...
