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:
Cyclic nucleotides form when the phosphate group is bound to two of the sugar's hydroxyl groups. Ribonucleotides are nucleotides where the sugar is ribose, and deoxyribonucleotides contain the sugar deoxyribose. Nucleotides can contain either a purine or a pyrimidine base.Nucleic acids are polymeric macromolecules made from nucleotide monomers. In DNA, the purine bases are adenine and guanine, while the pyrimidines are thymine and cytosine. RNA uses uracil in place of thymine.racil pairs with adenine through hydrogen bonding. Uracil is the hydrogen bond acceptor and can form two hydrogen bonds. Uracil can also bind with a ribose sugar to form the ribonucleoside uridine. When a phosphate attaches to uridine, uridine 5'-monophosphate is produced.
