The drink of the gods
curbs oxidative stress through
clever conversions
The energetic demands of flying causes muscular oxidative damage. Whilst some foods have antioxidants, nectar doesn’t – a potential issue for flying nectar-feeding animals. To get around this issue hawkmoths appear to be able to “generate antioxidant potential by shunting nectar glucose to the pentose phosphate pathway”. Levin et al, 2017.
