Tails of phospholipids that dont like water?
Phospholipids have a lipid tail. This is non-polar and therefore hydrophobic (water hating). The phosphate head is polar and hydrophilic (water-loving).
What characteristics of phospholipid is important to their function?
they have a polar head and non-polar tails
Which molecules have heads and tails in the plasma membrane?
phospholipid molecules....they have polar hydrophillic head(like water-as there is phosphate group attached on it..phosphate group has oxygen molecules with all their pairs of unshared electrons.) and hydrophobic tails(scare water)
Why are proteins amphipathic?
Because the heads of the phospholipids are hydrophilic (water loving) and the tails of the phospholipids are hydrophobic (water hating). The tails are pointing towards each other and the heads are facing the membranes.
The lipids within the fluid mosaic of the plasma membranes are held in place by?
the phospholipids in the membrane are not actually held together by anything. They stay together because the heads are hydrophilic (water loving) and the tails are hydrophobic (they do not like water) so they line up in a bilayer with the tails on the inside and the heads on the outside and stay like this because of what each end of the phospholipid is attracted to
What part of a cell membrane is hydrophobic?
Phospholipids
Do phospholipids of the plasma membrane have hydrophobic heads and tails?
Hydrophobic means water fearing tails and hydrophilic means water loving heads First of all, these terms are involved when you are looking at the cell membrane. The structure of the cell membrane is called a phospholipid bilayer. Which means that the cell membrane is actually made to two layers and not one. If you take a look at the image, you will see that the little white sphere shaped objects are the hydrophilic heads, and the two little string-like objects attached to the hydophilic heads are the hydrophobic tails. All of the other stuff in the image is all of the extracellular proteins and such. But yes, as the previous answerer said. The hydrophilic heads are on the outer part of the bilayer because they are "water loving". Whereas the hydrophobic tails are on the inner part of the bilayer for two reasons. First, they are hydrophobic or "water fearing" so they will repel water. An example of hydrophobic is oil in water. The oil will form blob-like shapes in the water. Second, the hydrophobic tails also have a somewhat attraction to each other.
How do the hydrophobic and hydrophilic properties of phospholipids help in maintaining the structure of the cell membrane?
Hydrophilic molecules are attracted to water. Hydrophobic molecules are not attracted to water, but they are attracted to each other. Phospholipid molecules are unusual because they are partly hydrophilic and partly hydrophobic. The phosphate head is hydrophilic and the two hydrocarbon tails are hydrophobic. In water, phospholipids form double layer with the hydrophilic heads in contact with water on both sides and the hydrophilic tails away from water in the centre. This arrangement is found in biological membranes. The attraction between the hydrophobic tails in the centre and between the hydrophilic heads and the surrounding water makes membranes veery stable.
Why do you not have a tail like your cat?
because we are human human dont have tails
What gives the plasma membrane the ability to self-reassemble?
Hydrophilic end
In what way is a membrane fluid?
it moves very water-like, almost like the phospholipids are floating ping pong balls on water always adjusting.
What are tails of phospolipids that don't like water?
they're hydrophobic or "water fearing"
