Today’s graphic looks at the 20 common amino acids that are combined to make up the proteins in our bodies. It also gives the three-letter and one-letter codes for each, as well as denoting whether they are ‘essential’ or ‘non-essential’.

With autumn on the horizon, this graphic looks at the chemicals behind the myriad colours of autumn leaves; bigger version & download here:

Today’s graphic takes a look at some of the different classes of antibiotics, and how they act to combat bacterial infections.

You can see a bigger version of the graphic, and read more information on each of the classes, in the accompanying post:

We’re heading into the tail end of summer - which, in the UK at least, means blackberry picking! Here’s a brief look at the chemicals that give blackberries their colour, including one that’s thought to be completely unique to blackberries.

Don’t forget you can reach plenty of other food-related posts via the food chemistry section of the site:

Today’s graphic looks at xylitol, a compound frequently found in sugar-free chewing gums, and the scientific evidence behind its use to help prevent tooth decay:

This graphic was made for Sweet Bites, a team of US students hoping to help combat tooth decay in India’s slums through the distribution of xylitol gum. They’re amongst the finalists for the upcoming Hult Prize; you can read more about their campaign on their website:

Studying organic chemistry this year? You can now download PDF files of all the organic chemistry graphics posted to the site so far, including all the reference sheets, reaction maps, isomerism and formulae guides, right here:

If you’re currently taking a course that includes some organic chemistry, today’s graphic might be a handy reference! It summarises a selection of benzene derivatives, including their common names and systematic names.

This year’s Longitude Prize is focused on the growing problem of antibiotic resistant bacteria. They’ve put together a nice image, shown here, which showcases what they term ‘the ten most dangerous antibiotic resistant bacteria’. You can read more detail on each of them here:

The prize offers a £10 million prize fund for the development of a cheap, accurate, and easy to use bacterial infection test kit, which will allow doctors to prescribe the correct antibiotics at the correct time for patients, to try to help minimise the development of antibiotic resistance.



A final word on insect venoms, with a look at the Schmidt Pain Index, developed by Dr. Justin Schmidt to rank the pain of the various insect stings he experienced in his line of work. Whilst obviously pain is subjective, and you’d expect some variation from person to person, it still makes for an interesting graphic!

I thought velvet ants were considered wasps. >:

It seems they are indeed! I got caught out by that one, assuming from the name that they were ants. I’ll blame being a chemist; I assumed biologists would name things based on what they are, so I didn’t double check :) I’ll change it on the post on the site!
