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:
Two decarboxylation reactions occur in the cycle to yield two carbon dioxide molecules and the oxaloacetate is regenerated to begin another cycle. The net result is that one turn of the citric acid cycle yields two carbon dioxides and energy stored in electron carriers (NADH and FADH 2).n the second part of the citric acid cycle, succinyl-CoA is converted back to oxaloacetate (see also Figure 14.3), thus making it possible to begin the process again. In each turn of the citric acid cycle, two carbons are added from acetyl-CoA and two carbons are oxidized as CO 2.
