|
Are lipids hydrophobic or hydrophilic
|
hydrophobic, they reject water
|
all lipids are insoluable in water
|
|
|
What are the three kinds of lipids that are vital to life?
|
Fats
phospholipids steroids |
|
|
|
Describe fats
|
store in body, large molecules, store alot of energy, one type is the atopole cell which give the body shape.
|
|
|
|
Describe phospholipids
|
used to make membranes
|
|
|
|
Describe steroids
|
based on cholestrol, small lipids examples of them include testerone,estrogen, etc.
|
|
|
|
hydrophillic vs hydrophillic
|
water loving water hating
|
|
|
|
why are fats important?
|
because they store a great deal of energy
|
|
|
|
What are macromolecules constructed from?
|
Glycerol which is in alcohol. It's the back bone of the system with three fatty acids attached. And fatty acids
|
macro molecules are large.
|
|
|
how many fatty acids does glycerol have?
|
three
|
|
|
|
what does it mean when something is said to be non-polar
|
it repels water
|
|
|
|
What are some aspects of saturation
|
no double bonds,no kinks, carbond bonded to maximum number of hydrogens(literatly satuarated with hydrogens) it's solid at room temperature.Most animal fats.
|
|
|
|
What are some aspect of unsaturated
|
one or more double bonds FA don't pack tightly due to kinks, usally liquid at room temperature, most plant fats
|
|
|
|
what is the structure of a phospholipid
|
One hydrophillic head and two hydrophobic tails
|
|
|
|
What is a phospholipid MADE of
|
Glycerol backbone, two fatty acid chains
|
|
|
|
two structures formed by self-assembly of phosphlipids in aqueous enviroments
|
micelle- circle with tails inside and heads outside and phospholipid- the bilayer look with parallel lines.
