Biological macromolecules genetic code

Macromolecules of biological origin perform various functions in the body. For example, proteins which perform the role of biological catalysts in the body are called enzymes, those which are crucial to communication system in the body are called receptors. Carrier proteins carry polar molecules across the cell membrane. Nucleic acids have coded genetic information for the cell. Lipids and carbohydrates are structural parts of the cell membrane. We shall explain the drug-target interaction with the examples of enzymes and receptors. [Pg.163]

Even though we stated at the beginning of this section that it is not our purpose to discuss the biological function of the macromolecules described, it is hard to resist saying a few words about some of their most important interactions. First, it is easy to visualize how the structure of DNA leads to its replication and hence the transfer of genetic information which is coded in the sequence of bases along the chain. Specifically, when the DNA double helix opens up it exposes the sequence of bases in each strand of the molecule. In a solution where bases, sugars and phosphates are available or can be synthesized, it is possible to form the complementary strand of each of the two strands of the parent molecule. This results in... [Pg.504]
