Concept introduction:
Lipids are organic compounds, which are fatty acids or the derivatives of fatty acids. They are insoluble in water but are soluble in non-polar organic solvents. They include natural oils, waxes, and steroids.

fatty acid naming 1
A fatty acid contains 18 carbon atoms and has two double bonds. The first is between
carbons 3 and 4 and a double bond is between carbons 7 and 8, both measured from the end
of the hydrophobic chain (away from the carboxylic acid end). What do we call this type of
fatty acid?

- How do the unsaturated fatty acids in phospholipids affect the structure of cell membranes? Match the words in the left column to the appropriate blanks in the sentences on the right. Reset Help stronger In the cell membrane, the unsaturated fatty acids contain that cause the phospholipids flexible and fluid-like to This causes the cell membrane to be rigid and fixed double bonds fit closely together steroids proteins extend through the membrane triple bonds not fit closely togetherarrow_forwardThere are structural differences between saturated fatty acids, cis-unsaturated fatty acids, and trans-unsaturated fatty acids. • Why have some cities banned the use of trans-unsaturated fatty acids at restaurants? Trans-unsaturated fatty acids stack like unsaturated fatty acids and cost more energy to metabolize, making it substantially more dangerous to consume. Trans-unsaturated fatty acids stack like saturated fatty acids and cost more energy to metabolize, making it substantially more dangerous to consume. Trans-unsaturated fatty acids stack like saturated fatty acids and cost less energy to metabolize, making it substantially more dangerous to consume. None of the other answers are correct.
