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 into a small amount of venom. The range of compounds is far too vast to detail every single one – but we can examine some of the major constituents in bee, wasp, hornet and ant venom.

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 people are just that much more attractive to the humble mosquito than others.

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 more an area of interest than an area of expertise for me, I’ve kept it pretty general.
