Don't know how likely it is that you'll even get a question pertaining to cyclic sugars but know those 5 for sure. Upvote 0 Downvote

I would know glucose, galactose (c-4 epimer) and fructose.. others are very low yield. Upvote 0 Downvote

Just know the fructose has a 5-carbon (well I suppose one's an oxygen) ring and galactose is the C-4 epimer of glucose. Upvote 0 Downvote
