1. The major function of cellular membranes is compartmentalisation. As plasma membranes they separate the cells from their external environment. As organelle coverings, they allow the cell organelles to maintain their identity, specific internal environment and functional individuality. ADVERTISEMENTS:...
MembranesIf peptides consist of nonpolar residues only, they become inserted into the nonpolar phase. As demonstrated by the example of the leucine undecamer, such peptides fold into an a-helix as they partition into the nonpolar medium. The folding proceeds through an intermediate, called the ...
Lipid remodeling, defined herein as post-synthetic structural modifications of membrane lipids, play crucial roles in regulating the physicochemical properties of cellular membranes and hence their many functions. Processes affected by lipid remodeling include lipid metabolism, membrane repair, cellular homeost...

cell. Water and carbon dioxide are two molecules that can travel across the cell membrane easily. Glucose is an example of a molecule that is moved across the cell membrane through a protein transporter. Glucose cannot freely move across the cell membrane but is needed as fuel forcellular ...
Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized function

Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house, the plasma membrane is semi-perme...

Plant-specific aspects of membrane biology are reviewed by international experts in the field. The 31 chapters are grouped into 6 main subject areas: membranes and the cell surface (9 chapters discussing the specialized functions of the plant plasma membrane within its cellular context); membrane li...
