Analyze, describe, explore, look into the applications and usages of a biologically-active molecule that you use (or have heard of) and find it interesting to write an essay about. 

Here are just some ideas:

–          sugars – carbohydrates  

–          proteins

–          enzymes

–          fatty acids – trans, saturated or any specific one

–          metabolism of a certain food

–          nucleic acids – how they carry genetic info

–          drugs – the good ones and/or the “bad” ones Essay should be approximately two pages, and adequate to cover your topic.  Imagine writing a paper for a magazine, making sure to cover the topic so that your audience/readers can understand you.
