Lets compare the angles between a 4 and 6-sided ring. 4-sided rings have a bond angle of 90 degrees (Higher strain), and a 6-sided ring has a bond angle of 120 degrees (Lower Strain). Thus a six-sided ring is more favored. combination coffee espresso makers

"WebSummary. 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 … " - Cyclic form of sugars
