Do Hydrophobic molecules pass through the fatty-acid region of the plasma membrane easily?
no
Which subclass of lipids is important in membrane structure?
i think it may be fatty acids
How does the structure of fatty acids compare to the basic units found in macromolecules?
why are fatty acids important to the cell membrane
What structure in the membrane causes plasma membranes to resist freezing?
Unsaturated fatty acids tails.
What macromolecules make up the cell membrane?
The cell membrane is composed of a bilayer of phospholipids, which are composed of a glycerol molecule chemically combined with a polar hydrophilic phosphate head and two hydrophobic fatty acid tails.
Small nonpolar hydrophobic molecules such as fatty acids?
Small, nonpolarn hydrophobic molecules such as fatty acids easily pass through a membrane's lipid bilayer.
How would a non polar molecule such as a fat or oil travel through the plasma membrane?
The inside of a membrane is "hydrophobic" because of the hydrophobic fatty acid tails of the phospholipids.
Do Hydrophobic molecules pass through the fatty-acid region of the plasma membrane easily?
no
What chemical structure make up the cell the membrane?
The main component of the cell membrane is phospholipids. These are molecules with a polar (hydrophilic, water-loving) head composed of a phosphate (and usually a choline) and a non-polar (hydrophobic, water-hating) tail composed of fatty acids. In the cell membrane, these phospholipids are arranged in a bilayer - with heads facing the outside and the tails facing each other in the center of the membrane.
Hydrophobic interactions of the tails of phospholipids can produce a. a cytoskeleton. b. a protein membrane. c. a nonpolar membrane. d. a lipid bilayer. e. hydrolysis of the fatty acid?
a lipid bilayer

How would the membrane shown in transparency behave if it's fatty acid tails consisted mostly of unsaturated fatty acids?
The lipids would flip and the heads become hydrophobic and the tails hydrophilic
How do hydrophobic and hydrophilic relate to the structure of a cell membrane?
The cell plasma membrane is made of bipolar fatty acids with the fatty (uncharged) hydrophopic part pointed towards the inside of the plasma membrane and the hydrophillic (charged) part facing the inside of the cell or the outside of the cell.

Is triglycerides hydrophilic or hydrophobic?
These molecules are highly hydrophobic because the long chains of fatty acids esterified to a glycerol molecule. They are the most important lipids in plasma membrane that form the so-called lipid bilayer. When the fatty acids present in triacylglycerols are saturated, they become a strong water repelent to the cell. When these fatty acids have one or more unsaturated bonds, they turn to be more akin or water tolerant. While the unsaturated bonds are more present in fatty acids, the more water tolerant they will be.
