Acid on cell membranes

Post by caulfc » Mon Mar 06, 2006 9:05 am

What do acidic solutions do to cell membranes?
I think or teacher says they creates holes and allows the pigment to leak out but which part of the cell membrane does it affect? :?:

I read the post about beetroot and temperature and now we're doing that prac but I need help writing up this one, please help if u know...

The acid would probably affect the tertiary structure of the proteins (Intrinsic and extrinsic) held within the bi-layer of the phospholipid membrane.

This causes the proteins to denature and unfold, causing the "holes" that your teacher has mentioned.

mio is right

just to add on the excessive h+ ions affect the hydrogen bonding in secondary, tertiary and even quatenary structures
it isn't what you do that matters but it is how you do it
