A community's members are a rich source of knowledge about their community and of energy and commitment to that community. When public health professionals envision a program to address health issues in a particular community, tapping into the community's expertise and enthusiasm is frequently an essential issue.
1 The two forms are sometimes described as  anomers  since they are isomers at the anomeric center. 2  To assign the cyclic form of a carbohydrate as the Î±- or Î²- form look at the relative positions of the-CH 2 OH group and-OH (or-OR) group at the anomeric center. In the Î²- form, the exocyclic O group at the anomeric center is on the same face as the-CH 2 OH group. 2  If a mixture of the Î±- and Î²- anomers are present, then this is often represented by using a wavy line to represent the bond:
Amylose and cellulose are both linear polymers of glucose units, but the glycosidic linkages between the glucose units differ. The linkages in amylose are Î±-1,4-glycosidic linkages, while the linkages in cellulose they are Î²-1,4-glycosidic linkages.b) Because of hydrogen bonding, amylose acquires a spiral structure that contains six glucose units per turn. Amylopectin is a branched-chain polysaccharide composed of glucose units linked primarily by Î±-1,4-glycosidic bonds but with occasional Î±-1,6-glycosidic bonds, which are responsible for the branching.
