A fatty acid has a hydrophobic tail this means that it does not like to come into contact with water, like when oil wont mix with water and satys separate as a layer or blobs under the surface.

Why is the phosphate the polar part of the phosphilipid?
The phospholipid heads are hydrophillic and prefer the water while the tails are hydrophobic and are shielded from the water.
True or False.The cell membrane is formed by phospholipids with hydrophobic fatty acid tails facing outward to the cytoplasm and extracellular fluid and hydrophilic phosphate heads sandwiched between?
true
When mixed with water phospholipids spontaneously form membranes. what properties of phospholipids cause this to happen?
Hydrophilic phosphate groups that are attracted to water and hydrophobic fatty acid tails that avoid water.
Do Hydrophobic molecules pass through the fatty-acid region of the plasma membrane easily?
no
In a plasma membrane is a hydrophilic portion oriented to the outside of the cell?
Yes, the phosphate head which are hydrophillic is facing outside the cell and inside the cell. (Its a bilayer of phospholipids, and the fatty acid tails(hydrophobic) face each other)
Hydrophobic reactions of phospholipids may produce clusters of their fatty acid tails which form what?
lipid bilayer
What part of the fatty acid is hydrophilic?
A fatty acid consists of the polar acidic -COOH functional group and the non-polar alkyl CnH2n+1 chain, which in most cases, n=15-18. A triglyceride consists of distinct hydrophillic (glycerol) and hydrophobic (fatty acid) sections, but to answer your question, the fatty acid itself has a hydrophillic part which is the -COOH group.
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 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.
What is the Function of fatty acids?
Fatty acids are used to make lipids in a cell. They also attach to a phosphate group to form phospholipids, the phosphate head being hydrophilic and the two fatty acid tails being hydrophobic, that are used to form the lipid bilayer in the cell membrane.
Which part of phospholipd molecule is non polar and hydrophobic?
The fatty acid tails of the phospholipid is hydrophobic.
Are fatty acid tails of a phospholipid molecules polar?
This is called the hydrophobic 'side' of the phospholipid molecule
The nonpolar end of a fatty acid is said to be?
Hydrophobic
Why is the phosphate the polar part of the phosphilipid?
The phospholipid heads are hydrophillic and prefer the water while the tails are hydrophobic and are shielded from the water.
What is the function hydrophilic heads?
Hydrophobic is the tail of the the molecule that is atrracted to fatty acids and is a water fearing subtance. Also the tail is None-Polar. Hydrophilic is fatty acid fearing and is attracted to water it is the head of the hydrophobic tail. The head is polar.
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
True or False.The cell membrane is formed by phospholipids with hydrophobic fatty acid tails facing outward to the cytoplasm and extracellular fluid and hydrophilic phosphate heads sandwiched between?
true
