Membrane Structure And Function
Instructor: Raed Alkowni
Instruction Year: 2021 (Second Semester)
Membranes consist largely of a lipid bilayer, which is a double layer of phospholipid, cholesterol, and glycolipid molecules that contains chains of fatty acids and determines whether a membrane is formed into long flat sheets or round vesicles. Lipids give cell membranes a fluid character, with a consistency approaching that of a light oil. The fatty-acid chains allow many small, fat-soluble molecules, such as oxygen, to permeate the membrane, but they repel large, water-soluble molecules, such as sugar, and electrically charged ions, such as calcium
