| − | <h2>ANTHOCYANINS</h2>
| + | /* Creates the container for the content */ |
| − | A class of pigmented (blue, red and purple) compounds which are members of the flavonoid group of phytochemicals, possessing aromatics structures with bioactive properties. They are produced through a complex biochemical pathway involving the actions of multiple enzymes, as seen in Figure 1. The initial substrate of this pathway is phenylalanine, which is a common amino acid utilized by all living organisms. Some natural sources of anthocyanins include honey, fruits and vegetables, nuts, cocoa and olive oil.<br>

| − | Anthocyanin compounds are free radical scavengers which sequester harmful reactive oxygen species, thereby acting as antioxidants. Anthocyanins provide a variety of physiological benefits to humans. Some such benefits include:<br>

| + | border-top: 14px solid #565656; |
| − | The mass production of anthocyanin compounds may have significant implications in the treatment and prevention of a large number of diseases and disorders. Therefore the goal of this project is to produce a recombinant strain of Escherichia coli which is capable of expressing the anthocyanin biosynthetic pathway. This will lead to the visualization of a blue phenotype when the strain is cultured. This project is modelled on a previous application of synthetic biology involving the expression of the lycopene pathway in E.coli by Klein-Marcuschamer et al (2007).
