Ribose's structure is ОН HO ОН ОН a) Draw using the arrow formalism the reaction of linear ribose to make a 5-membered ring. b) What is the name of the resulting functional group? c) Given that reaction of alcohols (such as RCH2OH) with carbonyls (such as HCO-R') to create this functional group is typically not thermodynamically favored, why does most ribose in water exist as a 5-membered ring? A few word answer is fine. d) AG°for this reaction is about - 5 kJ/mol. Assuming that you start with a 1 mM solution of ribose in water, what is the approximate concentration at equilibrium of (i) the linear form? (ii) The cyclic form? (A good answer should be correct within 20%, e.g. it is fine to approximate 9 mM as 10 mM, but it is not okay to approximate 0.1 mM as 1 mM.) e) This reaction creates a new stereocenter.
