Phospholipid bilayer cholesterol function

WebWhat is a phospholipid? Type of lipid made from 2 fatty acid chain “tails” attached to a phosphate group “head”. Describe the phospholipid’s polar nature and how it interacts with water. Phosphate head group is polar and hydrophilic. Fatty acid chains tail is non-polar and hydrophobic. Thus, heads face water and tails point inwards ... WebA) membranes are a phospholipid bilayer. B) membranes are a phospholipid bilayer between two layers of hydrophilic proteins. C) membranes are a single layer of phospholipids and proteins.

This amphiphilic nature yields the formation of … WebA) Cholesterol binds to the outside surface of a membrane, thus blocking the movement of solutes. B) Because cholesterol is amphipathic, it forms tiny vesicles that trap solutes. C) Because cholesterol is amphipathic, it fits in between the phospholipids and blocks diffusion through the membrane. example of holocrine secretion https://oib-nc.net
