What molecules are on the outer surface of the plasma membrane?
The outside surface of the plasma membrane is made of a layer of molecules called phospholipids, which have hydrophobic and a hydrophilic parts. The hydrophilic parts are on the outside surface, attracted by the water and other hydrophilic molecules outside the cell. There are also proteins of various kinds attached to and embedded in this outer layer.
What is an explanation of hydrophobic and hydrophilic substances?
The suffix "philic" means roughly" loving" or "attracted to". The suffix "phobic" roughly stands for "fear" or "fearful". The prefix "hydro" means water. Putting it together, a hydrophilic substance is a substance that is attracted to water, while a hydrophobic substance repels water. A good example of this is glass. Glass is naturally hydrophilic. The problem is, on windshields, water actually hinders our vision. Enter RainX. RainX coats the windshield and gives the glass its hydrophobic properties, therefore causing rain to bead up and drip down off the windshield allowing us a clear view of the road.
Compounds that hate or repel water are labled as?
All things that repel water are called "hydrophobic" which is a latin term. Hydro, meaning water, and phobic, meaning the fear of. So literally they are water fearing. Something that does not repel water is called hydrophilic.
When substance attracted to water is called?
A substance that attracts water molecules is hydrophillic, hydro meaning water and phillic meaning attracted to. The opposite would be hydrophobic, hydro meaning water and phobic meaning scared of.
What is a lipid with a water attracting and water repelling part of its molecule?
Any phospholipid has a hydrophilic head and hydrophobic tail. These are the lipids that are most common in cell membranes, which require this amphipathic property to function. Other lipids, including many sphingolipids, are also amphipathic.
How do you make the different textures of chocolate?
Materials that are hydrophobic (dislikes water) versus hydrophilic (likes water). The cocoa mass in chocolate is hydrophilic, whereas the hydrophobic cocoa butter fat molecules are composed mainly of carbon and hydrogen and do not readily interact with water. Hydrophobic and hydrophilic materials do not mix well. So an amphiphilic molecule (that likes both water and oil) is added. Such a mixture is called an emulsion. An "emulsifier" that is commonly added to chocolate is soy lecithin ,that promotes mixing of cocoa solids and cocoa butter: these amphiphilic molecules coat the hydrophilic cocoa solids with a hydrophobic layer, thereby helping to maintain a stable chocolate, and making the chocolate feel smooth in your mouth.
Is CH3 hydrophobic?
methyl is hydrophobic because it is non polar. the c-h bonds have little electronegativity difference I believe. water is polar, and nonpolar things don't tend to react or dissolve in polar substances.
Are polysaccharides hydrophobic?
Yes. Sugars contain many polar hydroxyl groups, so they tend to be quite hydrophilic.
What is a hydrophobic bond?
There is no such thing as a hydrophobic bond, It is a hydrophobic force. These forces come about when two areas of 2 different molecules containing hydrophobic sections come close together. like in protein's the hydrophilic sections come together to form bonds and the hydrophobic sections come together and so are seen as bonds but in reality they are not bonding but are just brought together to keep the hydrophobic parts away from aqueous environment (see lipid bi layers as an example)
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.
What are substance that are water loving called?
Hydrophilic (water loving)
Why does the tail of the phospholipid molecule of the cell membrane has a hydrophilic head and a hydrophobic tail?
tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.

Is triglyceride hydrophobic?
yes
What is hydrophobic compound?
Oil is one of the best examples of substance that is hydrophobic which canÕt mix or dissolve with water. It is highly hydrophobic because the interaction in oil is more compact than other compounds.

Why is plasma membrane called a lipid bilayer and a fluid mosaic model?
It is often called the cell membrane because it is made up of phospholipid bilayers. It is also often called the plasma membrane. Each phospholipid joins together at the hydrophilic head, leaving the hydrophobic tail on the inside, and forming a bilayer.
