Toxicologist explains how poison ivy and bee stings are nature’s chemical weapons Poison ivy and bees stings are among the most common outdoor menaces for people enjoying the outdoors.

Plants and animals deploy toxins most often in order to defend themselves. Learning how they do that and what happens when the human body is exposed to these substances can offer insights on how to prevent or manage these encounters with nature. (via @us.theconversation.com)

🍋 ¹H NMR of Lemon Juice
Freshly squeezed science!
This proton NMR spectrum of lemon juice reveals a rich mixture of natural metabolites. The intense multiplets around 2.6–2.8 ppm are from citric acid, the dominant organic acid in lemon.

Infographic on the chemistry of poppies. The red colour of the common poppy is due to anthocyanin pigments. Other red poppies also contain anthocyanins but the yellow Iceland poppy and alpine poppy contain nudicaulin pigments. The opium poppy has been used in medicine for thousands of years, with the milky opium fluid which contains alkaloids such as morphine used as a painkiller. The common poppy contains different alkaloids, which only have very milld pain-killing properties.

On #RemembranceSunday, many countries use poppies as a symbol of remembrance.

This graphic looks at the chemical compounds behind poppy colours, as well as some of the useful medical compounds that can be obtained from different types of poppies: www.compoundchem.com/2020/11/11/p...
