Which of the following lipid types is NOT found in biological membranes? Glycerophospholipids. Cholesterol. Triacylglycerols. Sphingolipids. Gangliosides.
Which of the following statements are true about lipids? There may be more than one correct answer so make sure to check all answers that are true. Fats tend to be liquid at room temperature while oils tend to be solid. A saturated fat contains fatty acids that only have single bonds between each carbon in the carbon chain. The presence of multiple double bonds in a fatty acid make it more likely that the overall lipid will be a liquid at room temperature. Phospholipids are able to form a phospholipid bilayer due to the fact that they contain a polar component at the "head" of the molecule, and a long and relatively straight non-polar component at the "tail" of the molecule Fats, lipids, and steroids all have the same general structure involving a glycerol molecule and fatty acids.
Which of the following statements is true of fatty acids? Group of answer choices The more carbon atoms and nitrogen atoms present in a fatty acid, the shorter the fatty acid is. The more hydrogen atoms attached to carbon atoms, the more saturated a fatty acid is. All fatty acids are solid at room temperature. All fatty acids have only double bonds. All fatty acids have the same chain length.
Which of the following statements regarding trans fatty acids is FALSE? Trans fatty acids increase the shelf-life of processed foods. Trans fatty acids were saturated fatty acids prior to hydrogenation. A diet that is rich in trans fatty acids increases the risk of heart disease, and therefore trans fatty acids in foods must be labeled. Trans fatty acids are a byproduct of hydrogenating fats.
