1. Which of the followingstatements best describe lipids?Lipids are oily or greasy nonpolarO molecules, stored in the adipose tissueof the body.Lipids are a heterogeneous group ofO compounds, mainly composed ofhydrocarbon chains.Lipids are energy-rich organicO molecules, which provide energy fordifferent life processes.Lipids are a class of compoundscharacterized by their solubility innonpolar solvents and insolubility inwater.Lipids are significant in biologicalsystems as they form a mechanicalO barrier dividing a cell from the externalenvironment known as the cellmembrane.O All of the above

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.

Lipid molecules do not dissolve in water because all lipids are _______. Instead, lipid molecules attract other lipid molecules, forming tight clumps. When lipid molecules are stuck to a surface (such as hands or clothing), the lipid molecules stick to each other and the surface, and water will not wash them away. Fill in the blank: A. hydrophobic B. polypeptides C. acidic
