Major lipid component of cell membranes
13) A membrane raft is a(n) in the lipid bilayer of a cell membrane. 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).
