A they are solid at room temperature b.
At room temperature the plasma membrane is solid.
In the golgi apparatus d.
Saturated phosphatidylcholine lipids with tails longer than 14 carbons are solid at room temperature while those with fewer than 14 are liquid.
All cells have a plasma membrane.
Which of the following is a feature of lipids in plant membranes that best explains this difference.
B before partial hydrogenation the shortening was vegetable oil and therefore liquid at room temperature.
All cells have mitochondria.
What does this tell you about the triglycerides in lard.
Lard is a solid fat at room temperature.
C before partial hydrogenation the shortening was vegetable fat and therefore solid at room temperature.
The reason that saturated fats are solid at room temperature is that the molecules are able to pack much closer together.
All cells have a cell wall.
All cells have a nucleus.
A before partial hydrogenation the shortening was animal fat and therefore solid at room temperature.
Explain at least three functions that lipids serve in plants and or animals.
Membrane thickness most animal fats form a solid at room temperature while plant fats remain liquid at room temperature.
Melting temperature the fluidity ease with which lipids move in the plane of the bilayer of cell membranes has to.
They tend to dissolve in water easily.
A membrane surrounds every living cell keeping the cell s interior separated and protected from the outside world.
They are usually obtained from animal sources d.
The fats in lard are mostly phospholipids.
Think of a bag of dry macaroni noodles.
1 t m melting temperature is a phase transition a change from a more rigid solid like state to a fluid like state measures of membrane fluidity.
In the endoplasmic reticulum.
They have single bonds within the carbon chain c.
To learn better about the deoxygenation process of the studied fatty acids over our pt zif 67 membrane zeolite 5a bead catalyst we collected ftir spectra of some reaction products obtained from deoxygenation of lauric acid h 2 and co 2 atmosphere as a function of temperature seen in fig.
In the plasma membrane b.
All cells have a flagellum.
Think of a package of dry spaghetti noodles.
Many factors affect how this membrane behaves and temperature is one of the most important.
The plasma membrane of animal cells.
The reason that saturated fats are liquids at room temperature is that they can t fill nearly as much space with the same number of molecules.
Most animal fats form a solid at room temperature while plant fats remain liquid at room temperature.
