Are phospholipids and cholesterol the only membrane forming lipids?
Are there other types of steroids (besides cholesterol) that are found in membranes? I know that phospholipids and cholesterol are found in them for sure.
Answer: Yes. Other organisms besides animals have other steroid-like lipids in their cell membrane, ex. hopanoids in bacteria.
There are also other kinds of chain lipids such as sphingolipids.

What importance are phospholipids in the body?
I have a science project and I was wondering about phosphates, phosphorus, and phospholipids in the body. What do they do? How is it important to the cell membrane?
Answer: The phosphate group on the phospholipids is polar. This is important as this polar property enable it to be "dissolved" in water - the substances that surrounds most cells; the lipid group however, is unlike water - it is non-polar.
This means one end of the phospholipid will face towards the water, and the lipid end would face another phospholipid molecule. This means eventually a layer is formed (more accurately a bilayer) and this forms the cell membranes. The membrane is essential to any cell as it controls what substances can enter and leave the cell.

Why do Phospholipids form a double layer in the Plasma Membrane?
Im confused ?
WHY DO PHOSPHOLIPIDS FORM A DOUBLE LAYER IN THE PLASMA MEMBRANE?
Answer: well non-polar and non-polar mix together (oil and oil), and polar and polar mix together (like water).
now a phospho lipid, if we look at the name, is a lipid (non-polar chain), attached to a phosphate head (that is polar).
they basically look like tiny sperms, with a long non-polar tail and one polar end. So when you make a ball of them, the non-polars would go to the center, and the polar heads would go to the outside to be in contact with the surrounding water. when you make a bubble out of them, putting some polar water in the middle, the polar heads go out to the outside and the inside where the polar water is, and the non-polar lipids mix together in the membrane.

How would Phospholipids be distributed in a flask of water?
I know that the hydrophilic head would point out and the hydrophobic tail would point in to form chains, rings etc. But here is the question-
TO completely fill a sealerd 500 ml glass container that contains 490 ml distilled water you inject 10 ml of phospholipids. You shake this mixture vigourously and hten let it settle for an hour. Draw a diagram to show how the phospholipids would be distributed in the container.
Answer: In order to make sure that the hydrophobic tails are away from water and hydrophilic heads are in it they form a phospholipid bilayer. Which is literally a circle inside a circle each made of phospholipid heads. The tails would be in between the two circles, and are able to move from side to side.
This is what happens in cell membranes. This is how they would be distributed in the container.
For a visual example search phospholipid bilayer on google, will make much more sense.

What would happen to the phospholipids when they are added to a SEALED container of water?
To completely fill a sealed 500 ml container that contains 490 ml distilled water, you inject 10 ml of phospholipids into it. you shake the mixture and let it settle for an hour. what would the phospholipids look like?
Answer: The phospholipids would still form a phospholipid bilayer, regardless of whether the container is sealed or not. This is because phospholipids are made of two components: a phosphate head that is polar and hydrophilic (water loving), and two fatty acid chains which are non-polar and hydrophobic (water fearing).
When you put phospholipids in water, the phosphate heads immediately assemble so that they face the outside whilst the fatty acid tails face the inside.
This allows the water loving phosphate heads to interact with the water and the water fearing fatty acid tails to stay away from the water, keeping both components of the phospholipids happy!

Why do the hydrocarbon tails of membrane phospholipids provide a barrier to cell?
Why do the hydrocarbon tails of membrane phospholipids provide a barrier between the inside and outside of the cell?
Answer: The heads of the phospholipids are polar, causing them to orient towards the aqueous environment. The tails are non-polar. This means that they want to avoid the aqueous environment as much as possible. The polar water molecules outside of the bilayer will not be attracted to the tails.

What affect does heat have on phospholipids?
hi could anyone explain the affect that heat has on phospholipids, especially in the bi-layer, i undersatnd that heat makes it more fluid but i dont understand how, if anyone could explain it would be greatly appreciated, thanks.
Answer: Till certain temperature it functiones normally(37 C).Extremely low stalls its functiones.Increasing heat has a negetive effect on phopholipids.Its increases its fluidity i.e the bilayer disintegrates.It is apparent from the beeroot expriment wherein you see the effect of heat on the bi lipid layer of beetroot .The layer exposed to temperature give s away and so the colour from the beetroot comes out in to the envitronment giving a pink colour solution.

Why can phospholipids disperse in water if they are lipids?
Fats do not dissolve in water whereas phospholipids used to form membranes can disperse in water to form micelles. Why is this?
Answer: Phospholipids have a hydrophilic group on the end opposite from the fatty acid chains. When they form micelles, the hydrophobic fatty acid chains will be pointed towards the center of the micelle, while the hydrophilic phosphate groups will be pointed outwards toward the water.

How come phospholipids rarely filp from one layer to the other in most membranes?
Phospholipids can diffuse laterally in a membrane bilayer, but they rarely flip from one layer to the other in most membranes. why?
and, if you can answer this too:
cholesterol readily flips from one layer to another. why?
Answer: Think about the phopholipid bilayer. There is a huge polar gradient from the interior to the exterior. While it's possible for longitudinal flipping to occur, it's extremely energetically unfavorable. The energy incurred to overcome the polarity is quite high, instead phospholipids move around and flip laterally.
It's a matter of kinetics and good ol' delta-G

why phospholipids have a natural tendency to self-assemble into a bilayer.Why is this biologically important?
why phospholipids have a natural tendency to self-assemble into a bilayer. Why is this biologically important?
Answer: They are a type of molecule called surfactants (surface active agents). It's important because one side of the molecule is hydrophillic (likes water), the other side is hydrophobic (hates water). The hydrophobic ends all cluster together, giving the bilayer structure, the hydrophillic ends are exposed to water, allowing the structure to be stable in water. It's important biologically because these bilayers are what make up cellular membranes.

Why is a single layer of phospholipids better than a bi-layer one?
The cells of a plant seeds store oils in the form of droplets enclosed by membranes. Unlike the membranes of the endomembraneous system, the oil droplet membrane consists of a single layer of phospholipids rather than a bi-layer. Explain Why this arrangement is more stable than a bi-layer arrangement.
I need to write a paper on this and cant seem to find any information on them. Please, if you find a source or know of one, please send me the link. Thank You!
Answer: Hi. You can go to wikipedia and see the difference between Micelles and Liposomes:
http://en.wikipedia.org/wiki/Micelle
Because micelles are single layered phospholipid membranes they can enclose hydrophobic molecules such as oils. Liposomes are phospholipid bi-layers and the inside of them is an aqueous environment so it can contain hydrophilic molecules. A liposome could only contain oils between the two phospholipid layers, and not in the center of the liposome. That's why micelles are better for oils, they can contain oils in their center.

Why would phospholipids form a bilayer in water and not just a single layer?
Why would phospholipids form a bilayer in water and not just a single layer? thank you ahead of time!
Answer: because!
naw naw, see phospholipid is composed of a hydrophilic (water loving) phosphate head and 2 tails of hydrophobic (water hating) fatty acids. when grouped together, the fatty acid tails tend to line themselves up facing each other, away from the water. This makes sure that the phosphate heads ALWAYS face the water surrounding as they are hydrophilic.

What do the phospholipids do to form the cell membrane?
Science project, wondering about phosphorus, phosphates, and phospholipids. Tell me everything you know about the elements and its products. :)
Answer: Natural bilayers are usually made mostly of phospholipids, which have a hydrophilic head and two hydrophobic tails. When phospholipids are exposed to water, they arrange themselves into a two-layered sheet (a bilayer) with all of their tails pointing toward the center of the sheet. The center of this bilayer contains almost no water and also excludes molecules like sugars or salts that dissolve in water but not in oil. This assembly process is similar to the coalescing of oil droplets in water and is driven by the same force, called the hydrophobic effect. Because lipid bilayers are quite fragile and are so thin that they are invisible in a traditional microscope, bilayers are very challenging to study. Experiments on bilayers often require advanced techniques like electron microscopy and atomic force microscopy.
