While cholesterol adds firmness and integrity to the plasma membrane and prevents it from becoming overly fluid, it also helps maintain its fluidity. Therefore, cholesterol helps prevent extremes– whether too fluid, or too firm– in the consistency of the cell membrane.
Also to know is,Does cholesterol increase the melting point?
Add a comment. |. 1. In High temperatures, cholesterol stabilises the plasma membrane through raising the melting point, meaning the degree of fluidity is kept the same. In Low temperatures, cholesterol intercalates between the phospholipid bi-layer and therefore prevents clustering.
Similarly one may ask,Why do unsaturated phospholipids increase cell membrane fluidity?
A greater proportion of unsaturated phospholipids would tend to increase membrane fluidity because unsaturated phospholipids create more space and kinks inside the mosaic model cell membrane. When there are more kinks and space, the unsaturated phospholipids prevent the cell membrane from packing too closely together.
How does temperature affect the fluidity of the cell membrane?
In higher temperatures, phospholipids and other cell membrane molecules are already moving wildly (See Section 5: Higher Temperatures). Cholesterol itself is a chunky lad, so its bulky size will restrict the molecule movement within the membrane more. Thus, in high temperatures, more cholesterol decreases fluidity.
