What is the difference between a triglyceride and a phospholipid?
What is the difference between a triglyceride and a phospholipid? How does this difference account for the hydrophobic and hydrophilic nature of phospholipids?
Answer: I'm doing this at A-level now, are you?
We did this today...
A Phospholipid is Glycerol + 2 Fatty acids + 1 Phosphoric Acid
In a condensation reaction, this produces 1 phospholipid, and 3 water molecules.
The phosphate part of this has OH groups, which can form hydrogen bonds with water.
The fatty acid parts don't have Oh groups, so they are hydrophobic.
A triglyceride is made up of glycerol + 3 fatty acids (the phosphoric acid is replaced by another fatty acid, in comparison to the formula for phospholipid).
Because the phosphate part contained the OH group in the phospholipid, and it is absent in this molecule, triglyceride can not form hydrogen bonds, and so is hydrophobic.
hope this helps, i know research can be tricky, often there's either not enough, or too much more advanced information.

Phospholipid?
how does the chemical nature of a phospholipid affect its solubility?
and how does a cell membrane accomplish selective absorption?
Super Nova you wouldnt happen to know what a phospholipid added to water forms?
Answer: phospholipids have a hydrophillic head and a hydrophobic tail, which is why the heads face outwards and the tails face inwards. the chemical makeup of lipids makes them insoluble in water. this is due to the high amount of hydrogen atoms in lipids.
it accomplishes selective absorption/permeability because of the hydrophobic/hydrophillic interactions that keep large and/or ionically charged molecules out of the cell.

Describe the structure of a phospholipid bilayer using hydrophobic and hydrophilic, and its function in a cell?
Describe the structure of a phospholipid bilayer using hydrophobic and hydrophilic, and its function in a cell.
Answer: So the phospholipid bi layer is basically just the cell membrane. Microscopically there are little phosopholipids that make up this bi layer. They have a round head with two tails. These little guys are lined up right next to each other; there are also two layers of them. (kind of like a sandwich) The tails face each other while the heads face the outwards. The heads of the phospholipids are hydrophilic because they love water and can't survive without it. This make sense because where their heads are (facing outwards) completely surrounded by water. The tails are hydrophobic because they hate water. This works out great too because where the tails are touching there is no water. This whole situation makes the cell very protected because most molecules can't slip inbetween these tightly packed phospholipids and they can't pass through the middle (tail) layer because it's full of fat, not water.
Look at this picture, it will help you understand how this bi layer looks.

Whats the difference between lipid bilayer and phospholipid bilayer?
Is it just that the phospholipid bilayer has a phosphate group?
How are their jobs different in the cell membrane?
Answer: Lipids are hydrophobic so they are not water soluble. Phosolipids are used in the cellular membrane because their phosphate groups are hydrophylic and their 2 lipid tails form the inside of the membrane while the phosphate group makes up the 2 outsides of the membrane.

How many individual layers of phospholipid would a molecule cross to travel from the cytosol to the inner ?
How many individual layers of phospholipid would a molecule cross to travel from the cytosol to the inner compartment (matrix) of a mitochondrion?
none (0)
one (1)
two (2)
four (4)
eight (8)
Answer: To move from the cytosol to the inner matrix of a mitochondria the molecule will cross two membranes. Each mitochondria has an outer membrane as well as an inner membrane. Membranes are composed of phospholipid bilayers. The prefix bi in bilayer means two.
Each membrane has two layers of phospholipids to pass through. So passing through two membranes is passing through four layers of phospholipids. The sources below show great images as well as further explanations.

What is the difference between triacylglycerol and phospholipid?
How does this difference account for the hydrophobic and hydrophilic nature of the phospholipid molecule?
Answer: Starting from the basic structure, both of them start with a glycerol - you can think of that as an E-shaped molecule, with 3 "forks" to attach things onto.
Triacylglycerol has a long fatty acid carbon chain attached to each fork. This makes the whole thing pretty hydrophobic.
Phospholipids, on the other hand, have two long fatty carbon chains, and one phosphate group. The phosphate group is hydrophobic, while the carbon chains are hydrophilic. This makes the molecule "polar": hydrophobic at one end, and hydrophilic at the other end.
The polarity of phospholipids is the basis behind the formation of phospholipid bilayers.

Who was the first to propose that cell membranes are phospholipid bilayers?
Answer: Many people proposed the phospholipid bilayer. Charles Overton first hypothesized that membranes are made of lipids.
irving Langmuir came up with phospholipids. It was E. Gorter and F. Gredel who proposed the phospholipid bilayer, which grew into the sandwich model (Hugh Davson and James Danielli). That as now been replaced by the fluid mosaic model (S. J. Singer and G. Nicolson)

What would happen if you reversed a phospholipid bilayer?
In regards to a cellular membrane: Each phospholipid has a polar head and a non-polar tail. The polar heads face the inside and outside of the cell, while the non-polar tails are sandwiched in between. It is important for the cell membrane to interact with water-based solutions on the inside and outside of the cell to bring nutrients into the cell and expel waste products.
So what would happen to the cell if you reversed the bilayer so that the polar heads were sandwiched in the middle and the non-polar tails faced the outside?
Answer: They'd right themselves. Hell, you can throw a handful of phospholipids in a wet environment and they'll right themselves for that nice sphere.

Would it be possible for polar molecules or ions to move through the phospholipid bilayer?
Would it be possible for polar molecules or ions to move through the phospholipid bilayer? Why or why not?
Answer: Yes, this happens all the time in living cells, mainly because of transporters or channels that allow polar molecules and ions through the lipid bilayer of the membrane. Without such help, it is not likely that these polar molecules would find their way across the membrane.

What feature of a phospholipid makes them suitable for plasma membranes?
A) The uncharged,nonpolar,hydrophobic tails interact creating a membrane that is not permeable to most dissolved solutes.
B) The hydrophobic lipid portion allows water soluble molecules o freely diffuse through a phospholipid membrane
Answer: A. The plasma membrane has to act as a barrier for the cell. While some solutes freely passage the membrane, many must be actively transported across the membrane. This is how the cell controls its internal environment.

What is the difference between micelles and phospholipid bilayers? Similarities?
Am I even asking this question correctly? I know that a phospholipid bilayer is found in the plasma membrane and is composed of lipids with hydrophobic and hydrophilic ends. But what is a micelle as it relates to phospholipids? Thanks
Answer: You're right, a phospholipid bilayer is found in the plasma membrane with hydrophobic and hydrophilic ends.
A micelle also is made up of phospholipids with hydrophobic and hydrophilic ends. The difference being that it is composed of a single layer of lipids, no a bilayer.
With the membrane of a cell, there is water solution outside and inside with a double lipid layer separating the two. The hydrophobic tails face the interior of the bilayer.
The micelle is like a 'solid' sphere with all the hydrophobic tails pointing in and the hydrophilic ends on the surface of the sphere.

1. Describe roles of cell membrane parts.
2. Explain why a phospholipid must have water loving part and a water hating part.
I also need a link to a website with a phospholipid image with labeled parts.
Answer: a cell membranes purpose is to contain the cytoplasm and organelles the membrane is made up of a phospholipid bilayer.the bilayer consists of a hydrophillic head(water loving) and hydrophobic tails(water hating) this is to form a protective barrier, which at the same time allows water and nutrients to enter the cell.the hydrophillic layer aids in osmosis as water is attracted to it. the structure of the bilayer allows the cell to be protected, but at the same time non-rigid to allow movement in and out of the cell.
