    What is the difference between an alpha anomer and a beta .

    What is the difference between an alpha anomer and a beta anomer? an alpha anomer holds the alcohol group on off ring carbon 6 trans to carbon one's alcohol group, for the beta anomer the alcohol group on off ring carbon 6 is cis to carbon one's alcohol group. A beta glucose is a more stable molecule as more bulky substituents are equatorial, and it also has a higher melting point.

    Summary. The cyclic forms of carbohydrates can exist in two forms, α- and β- based on the position of the substituent at the anomeric center. The two forms are sometimes described as "anomers" since they are isomers at the anomeric center.To assign the cyclic form of a carbohydrate as the α- or β- form look at the relative positions of the -CH 2 OH group and -OH (or -OR) group at the .
