Solved in 2 steps
- Phospholipids are the only molecule type which make up lipid bilayers in plasma membranes True or False. Cholesterol is an integral part of plasma membranes. Based on its structure, where is it found in the membrane? On the extracellular surface embedded with the phospholipid heads within the tail bilayer attached to the intracellular surfaceWhich is NOT a phospholipid? cerebroside phosphatidylinositol cardiolipin phosphatidylethanolamine phosphatidylglycerol
- What is the common structural feature of all phospholipids and glycero esters? both contains glycerol both contains unsaturated and saturated fatty acids both contains phosphates . both A and B all of theseWhich of these general statements is TRUE about the lipid called phosphatidylethanolamine (or PE)? PE is NOT an aminophospholipid. 3 of these 4 responses are correct PE resides mainly in the outer leaflet of the membrane bilayer. PE is zwitterionic at normal cell pH. PE is a type of cholesterol.Which of these general statements is TRUE about the lipid called phosphatidylethanolamine (or PE)? PE is zwitterionic at normal cell pH. PE is an aminophospholipid. 3 of these 4 responses are correct PE is a type of cholesterol. PE resides mainly in the inner leaflet of the membrane bilayer.
- Phospholipids are synthesized within the cytosolic half of the smooth ER membrane bilayer. true falseIs the statement true? The individual glycerophospholipid molecules that aggregate become covalently linked to each other to form a lipid bilayer.Which statement about membrane lipids is TRUE? Question 7 options: Glycerophospholipids are found only in the membranes of plant cells. Lecithin (phosphatidylcholine), which is used as an emulsifier in margarine and chocolate, is a sphingolipid. Glycerophospholipids contain fatty acids linked to glycerol through amide bonds. Triacylglycerols are the principal components of erythrocyte membranes. Some sphingolipids include oligosaccharides in their structure.
- Name two glycerophospholipids found in eukaryotic cell membranes and two sphingolipids. What fraction of the lipid in most plasma membranes is cholesterol, and how does cholesterol content affect membrane fluidity? Note: be precise and go straight to the point. Adress what the question is asking you. I don't expect more than 5 sentences for an answer. I have experience with numerous tutors in the past with repect to the lenght of one response.A structural element, common in all glycerophospholipids is: O Palmatic acid. O Phosphatidic acid. O The fatty acid (18:1(D6). Phosphatidylcholine. O Ceramide.Characteristics of lipids: A Steroids are molecules characterized by cy- cles; B Diacylglycerol molecules are lipids found in the plasma membrane as well as in en- domembranes; C Waxes are aromatic molecules found in es- sential oils; D Sphingosine is an alcohol, which can con- tain a phosphate group; E Phospholipids are molecules found within the vacuole of an adipocyte.
