Web28 mei 2010 · Most simple carbohydrates exist predominantly as cyclic hemiacetals. For example, in water at 25° C, a solution of glucose contains less than 1% of the open-chain form at any given time! Likewise, fructose and ribose (and many other sugars, besides) are usually drawn as cyclic hemiacetals. WebAcetal and Hemiacetal are the main classes of carbohydrates i.e. organic compounds that differ in their functionality based on differences in the number of ether linkages present. Acetals are compounds with two ether (-OR) linkages whereas hemiacetals contain one such linkage. Acetals are the final...
