structure-function relationship of cholesterol Flashcards
1
Q
what is the function of cholesterol?
A
- to regulate membrane fluidity of the phospholipid bilayer
2
Q
how does cholesterol regulate membrane fluidity during low temperatures?
A
- in low temperatures, phospholipids have lower kinetic energy & move lesser, causing the membrane to be less fluid
- cholesterol increases membrane fluidity by preventing close packing of phospholipids, preventing membranes from freezing
