Glycerol and fatty acids corresponds with what?
Lipids.With two fatty acid tails, and a glycerol head, it is a phospholipid. If there is three tails, it is fat.
What is a phospholipid composed of by negative or positive heads or tails?
A non polar head and a polar tail
What is the major component of most cell membrane?
A cell membrane consists of a phospholipid bilayer. A lipid is a fatty organic compound in our body. The cell membrane is a double layer of these lipids. Each phospholipid is made up of a head (containing phosphate) and two tails(containing fatty acids). The head is polar and hydrophilic, or interacts with water molecules. The tails are nonpolar and hydrophobic, which means that they do not interact with water molecules. The polar heads of the lipids cluster together on the outer part of the layers while the nonpolar tails cluster in the center of the two layers. Polar means that it has a charge. (Biology Today and Tomorrow, Starr Evers Starr p. 48).
What is a phospholipid bilayer and where would you find it?
Phospholipids are polymers made up of two fatty acids, glycerol, a phosphate group and a polar molecule. A cell's membrane consists phospholipids where they form two layers (with the polar molecules facing opposite ends) to separate the interior of the cell from the outside environment. This is called a phospholipid bilayer.
The phospholipid molecules of most membranes have?
A hydrophilic head and two hydrophobic 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)
Which part of phospholipd molecule is non polar and hydrophobic?
The fatty acid tails of the phospholipid is hydrophobic.
What part of a phospholipid is non polar?
The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.
What part of the phospholipid is nonpolar?
the two fatty acid tails
Which parts of the phospholipid molecules that make up the plasma membrane face away from the watery environments?
The polar tails face away from the watery environment while the polar heads face the watery environment.
Glycerol and fatty acids corresponds with what?
Lipids.With two fatty acid tails, and a glycerol head, it is a phospholipid. If there is three tails, it is fat.
What makes the head of a phospholipid?
Phosphate molecules.
A molecule with a polar head and two non polar tails?
Lipids, man!Could be the phospholipid bilayer of a cell membrane to be more specific.phospholipidSoap and detergent molecules have a polar head and nonpolar tail to help dissolve an dwash off dirt and oil.
Why are fat soluble molecules the only molecules that permeate across a cell membrane?
Because small non polar molecules are the ones able to cross due to the fact that the membrane consists of a phospholipid bilayer where the middle is composed on non polar tails
How does polar phospholipid form a bilayer?
A lipid bilayer forms spontaneously whenever a collection of phospholipids is placed in water. This is because the amphipathic lipids (lipids having both polar and nonpolar regions) double up and put hydrophilic ends toward the outside and inside of the cell, whereas the hydrophobic tails are held in between the heads. A phospholipid is comprised of 1 polar head and two non-polar (fatty-acid) tails o<>o The polar region is comprised of a phosophate group (water-soluble) The non-polar region is comprised of fatty acids (water-insoluble)
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 a phospholipid composes of?
a head (phosphate group) and two tails (fatty acids)
