Affect of Methanol Concentration on leakage of beetroot pigment

Asked by Meeples | Mar 18, 2007 | AS Level > Biology > Coursework

Meeples asks:

I've seen lots of questions about how temperature denatures proteins in beetroot cell membranes, but what about using different methanol concentrations?
How does changing the pH rupture the membrane to get to the pigment in the vacuoles?

etutor answers:
Methanol dissolves the lipid bilayer. pH can denature the proteins in a similar way to high temperatures.
