5. Consider the following two molecules. The left structure is enterobactin, a siderophore (iron-binding molecule), which is used by microbes to obtain iron from the environment. The right structure is Amphotericin B, is an antifungal compound produced by certain filamentous soil bacteria. OH OH "OH NH OH OM OH HO OH OH OH OH O .
