Glad it helped!

Thank you! 😁

Thanks!

You get given the structures in the data sheet. Questions of this nature are rarely more than two marks so they’ll likely give you a partially complete diagram.

A zwitterion has to have no OVERALL charge. So each would have one NH2 group protonate and one COOH group deprotonated. Any further such groups would remain as they were.

@@simonflynn4515 thank you so much!

There’s a very specific place where the sugar attaches to a base.

You’re quite right - apologies for that.

@@simonflynn4515 great video though, it helped so much
