What is water loving and part of the phosolipid bilayer?
A molecule that is water-loving and part of the phospholipid bilayer is a phospholipid. Phospholipids have a hydrophilic (water-loving) head and hydrophobic (water-fearing) tail, making them ideal for forming the bilayer structure of cell membranes.
What is hydropholic?
There is no scientific term "hydropholic." It may be a misspelling of "hydrophilic," which means having an affinity for water. Hydrophilic substances tend to be soluble in water or have an ability to attract and interact with water molecules.
What part of the cell is a selective permeable membrane?
The phospholipid bilayer. plasma membrane
What part of the membrane can span over both layers of a membrane?
Phospholipid bilayer
Is there a part of a phospholipid bilayer that is polar?
The tails, the part that doesn't contain phosphorus, are non polar and they are hydrophobic (afraid of water).
What molecules are part of cellular membranes?
The main molecules are lipids (with different fatty acid chains depending upon the kind of membrane), proteins (that can be associated with the external part of the lipid bilayer, embedded in the lipid bilayer and those associated with the interior part of it ), and sugars (complex polysaccharides that can be part of the docking site of protein receptors, to have function of blood types, or to be recognized by antibodies).
What is another name for the phospholipid bilayer?
It depends on which lipid bilayer you're talking about. There is the phospholipid bilayer that surrounds eukaryotic cells, cholesterol phospholipid bilayers, protein lipid bilayers, phase transition lipid bilayer, lipid bilayer membrane...
Water freely moves through a phospholipid bilayer Why is this unexpected?
It moves through the bilayer via channels. These channels often are for transfer through the bilayer for other chemicals (sodium, potassium, etc) but also allow water to flow through readily. It is unexpected because water is hydrophilic (obviously- all charged molecules are). The phosphate part of the bilayer can bind with water, but the lipid on the inside of the bilayer acts like a layer of oil on the surface of the water- water cannot pass through the hydrophobic lipid.
What are the specialized parts of the phospholipid bilayer?
The Phospholipid Bilayer is made up of phospholipids. These phospholipids have a hydrophillic head, and a hydrophobic tail. They are structured so that the hydrophillic head interacts with water, and the hydrophobic tails stays away from water, but mixes with fat. This makes the phospholipids form the phospholipid bilayer. The Phospholipid Bilayer has intrinsic proteins and extrinsic proteins attached, which may have glycoproteins attached to them. Glycolipids may also be attached to the hydrophillic heads of the phospholipid. Cholestrol is also part of the phospholipid bilayer, which adds strengh to the structure.
What inner part of the bilayer is composed of fatty acid?
The inner part of a lipid bilayer is composed of fatty acid tails. These tails are hydrophobic, meaning they repel water and interact with each other to form a barrier that prevents water-soluble molecules from passing through the membrane.
What part of the cell membrane make up the bilayer?
Phospholipids make up the bilayer of the cell membrane. They have hydrophilic (water-attracting) heads that face outward towards the watery environment and hydrophobic (water-repelling) tails that align in the interior of the membrane.
How are the structures of the phospholipid bilayer and the plasma membrane related?
The phospholipid bilayer is the primary structural component of the plasma membrane. It consists of two layers of phospholipids arranged with their hydrophilic heads facing outward towards the aqueous environment and their hydrophobic tails facing inward, creating a barrier that separates the interior of the cell from the extracellular environment. Therefore, the phospholipid bilayer forms the basis of the plasma membrane's structure and function.
