Mish290 asks:

For my coursework I have to do some preliminary research on the pigment in beetroot. I have found out that it is called betalain, but I need to know what sort of molecule it it to know how it travels through the membranes. Can you help? Thank you

etutor answers:
You do not need to know too much detail for AS level - the only important feature of betalain is the fact that it is soluble in water, and so would go through the protein channels in the membrane - it won't be able to get through the lipid bilayer. If you really want to know more about betalain (but this is NOT necessary!) - have a look at http://www2.unil.ch/lpc/docs/pdf/Invitrocelldevbiol.pdf
