With autumn looming on the horizon, the leaves on some trees have already begun the transition towards the vibrant hues of autumn. Whilst this change may outwardly seem like a simple one, the many vivid colours are a result of a range of chemical compounds, a selection of which are detailed here.
Insect venoms are complicated. Really complicated. You could be forgiven for thinking that it must be a relatively simple company of chemicals that makes up the painful sensation of a bee or wasp sting, but in fact a hugely complex mixture of all sorts of compounds – proteins, peptides, enzymes, and other smaller molecules – go […]
With summer approaching, so too approaches the time to stock up on repellents for the seasonal onslaught of insects hungry for human blood. There are a number of different chemicals that are responsible for the repellent effects of the various sprays or creams available – and chemistry can also offer possible explanations for why some […]
Today’s graphic looks at the chemical compounds behind a variety of body odours – all of which we all experience at one point or another. Each is a cocktail of many different chemicals, but there are a select few that are major contributors to the distinctive aroma of each – here’s a look at some […]
A bit of a chemistry/biology tie in today with a series of posters looking at the chemical structures of some of the main neurotransmitters in the brain. I’ve also included a little information on the main effects and roles of each underneath the structures – however, I’d hasten to add that, since this is definitely […]
