What’s not to love about plants? They provide us with oxygen, food, medicine, fuel, fibers, and countless other things. They help filter groundwater and sequester carbon. They beautify our landscapes and communities. They provide habitat for wildlife and help reduce soil erosion. And the list goes on.

But there is more to plants than meets the eye. There is something deeper within – at their cellular and molecular levels – that is just as worthy of our fascination and appreciation as the blooms that beautify our yards and the fruits that fill our tables, and that is the abundant and diverse world of chemical compounds present in the botanical kingdom.

But how does one gain an understanding and appreciation for such a subject. Luckily, there is a blog for that. It’s called Compound Interest. Authored by UK chemistry teacher, Andy Brunning, Compound Interest explores the “chemistry and chemical reactions we come across on a day-to-day basis.” Much of what Andy writes about doesn’t have anything to do with plants – fireworks, bacon, gunpowder, snowflakes, etc. – but a sizeable portion of his posts do (evidenced particularly by the Food Chemistry category). For example: Did you know nutmeg is hallucinogenic? Have you ever wondered why avocados turn brown so quickly? Why is it that some people have such a strong aversion to cilantro (aka coriander)? What makes coffee bitter, chili peppers spicy, and catnip so attractive to cats?

These and so many other questions are answered by Andy in a fun and approachable way. One thing that makes Compound Interest so approachable is the use of infographics to tell the stories and explain the science. Each post is accompanied by an infographic featuring photos of the subject, structural formulas of the chemicals, and short descriptions.  For example, this infographic explains why beets are red and why our urine turns red after eating them:

The infographics can also be downloaded as pdf files, like this one that explains the chemistry behind the smell of fresh-cut grass.

In this manner, the images and files can be easily shared with others. In fact, Andy encourages this practice, provided that the originals are not altered and that Compound Interest is given proper credit. He is particularly interested in seeing his infographics used in a classroom setting. Read more about the content usage guidelines here. Produced by someone who is obviously passionate about chemistry, these posts and graphics are meant to educate and excite people about everyday chemistry both in the botanical world and beyond.
