A) transmembrane protein B) integral membrane protein oriented to the intracellular side C) integral membrane protein oriented to the extracellular side D) region of high cholesterol and sphingolipid content E) none of the aboveHow can the answer be improved? major lipid component of cell membranes

Apr 28, 2012 The main lipid components in cellular membranes are? a) b)fatty acids c)steroids d)triacylglycerols The cell membrane is composed of phospholipids and can be referred to as the phospholipid bilayer. What are the four components of the plasma membrane? Question about main functions of proteins?

Jun 01, 2015 The major components of a cell membrane are phospholipids, glycolipids, proteins, and cholesterol. The cell membrane contains more protein by mass, but the molar mass of a protein is about 100 times that of a lipid. So, bacterial and mitochondrial membranes have about 30 lipid molecules for every protein, and most of these are phospholipids. Phospholipids are a major component of cell membranes. Phospholipids form a lipid bilayer in which their hydrophilic (attracted to water) head areas spontaneously arrange to face the aqueous cytosol and the extracellular fluid, while their hydrophobic (repelled by water) tail areas face away from the cytosol and extracellular fluid.major lipid component of cell membranes The repertoire of membrane lipids. The major structural lipids in eukaryotic membranes are the phosphatidylcholine (PtdCho), (PtdEtn), phosphatidylserine (PtdSer), phosphatidylinositol (PtdIns) and phosphatidic acid (PA).

Section 12. 3 There Are Three Common Types of Membrane Lipids. Phospholipids Are the Major Class of Membrane Lipids. . Archaeal Membranes Are Built from Ether Lipids with Branched Chains. . Membrane Lipids Can Also Include Carbohydrate Moieties. . Cholesterol Is a Lipid major lipid component of cell membranes proteins are major components of membranes cell fusion experiments demonstrate that proteins are able to diffuse laterally within the plasma membrane. fluoresccently tagged antibodies used to specifically monitor the position of mouse and human proteins on the surface of cells The main components of cell membranes are lipids and proteins. Cell membranes are composed primarily of phospholipids arranged in a bilayer, as well as integral and peripheral membrane proteins. Phospholipids are a class of lipids, which are major components of cell membranes. The three subunits of phospholipids are phosphate, glycerol and fatty acids. Within a cell membrane, the primary type of lipid used is the phospholipid. Phospholipids form the majority of our cell membranes and are made from two primary parts. These parts are the hydrophilic phosphate head and the hydrophobic fatty acid tail. Hydrophilic means water loving, while hydrophobic means water fearing.
