Polysaccharides - polymer of sugar residues. Stored energy source. There is a broad range of characteristic times for biological processes. Putting the whole system together and keeping it running requires energy. We will be interested in both the sources and flow of energy.
Proteins are the workhorses for the cell.
The nucleic acids are the storehouse of information. They contain the information for making proteins. The Biological Blueprint We will consider how genetic information flows from DNA to direct the synthesis of proteins. We will also consider how humans have recently attained the ability to intervene in this flow of information to produce proteins having altered sequences. We then move on to consider the properties of some specific proteins.
