Create a Concept Map on the classification of lipids. There are two ways to classify lipid molecules, (1) biochemical functions (ex: storage lipids, structural lipids, membrane lipids, messenger lipids, etc), and (2) saponification characteristics (saponifiable vs non-saponifiable). I want you to be very detailed in your work and put some examples in each class. If there are subclasses then put them as well.

It's what makes food taste so good. Lipids or fats are relatively large molecules that pack a high-calorie wallop (over 9 kilocalories per gram, compared with about 4 kilocalories per gram for either carbohydrates or proteins). While that's great if your body's storing fat to make it through food shortage (imagine how much more you'd weigh if your body had to store an equivalent amount of energy in the form of carbohydrates!) it's not so great if you're consuming a half gallon of ice cream and trying to watch your weight at the same time. 12.1.

- The figure below illustrates the molecular structures of two fatty acids. A B H₂C The structural formula of erucic acid and behenic acid с H₂C D erucic acid behenic acid Which of the following best explains why erucic acid is liquid at room temperature but behenic acid is solid at room temperature? O OH The presence of a double carbon to carbon bond in erucic acid prevents the molecule from packing closely together. The lack of any double carbon-carbon bonds in behenic acid causes the molecule to be come polar and therefore packed more tightly. The larger number of carbon atoms in erucic acid prevents the molecule from packing tightly together. OH The smaller number of carbon atoms in behenic acid creates stronger covalent bonds between the carbon atoms allowing for them to pack more tightly together.arrow_forwardYou are studying the properties of an Antarctic fish and a tropical fish. What differences might you observe in the composition and/or structure of their lipids? Explain. **Hint: membranes should be flexible a balance between providing structure but also remaining fluid. For these applications, consider what type of lipids (length, number of double bonds) are needed to maintain that balance. You will not have to name the lipids, but describe their shape and structure. Also keep in mind that the hydrophobic interactions between the fatty acids themselves are the most crucial factors to fluidity and that backbones (glycerol vs. sphingosine) and head groups (e.g. phosphates, sugars, cholines, etc.) will not significantly alter fluidity.arrow_forwardHlons in Seawate...
