|
Hydrocarbons
|
Contain only hydrogen & carbon; are nonpolar (hydrophobic); lipids contain a lot of hydrocarbons, so they don't dissolve in water
|
|
Saturated
|
Hydrocarbon chains that consist of only single bonds between carbons
|
|
Unsaturated
|
Hydrocarbon chains that consists of one or more double bonds between carbons
|
|
Fats
|
Nonpolar molecules composed of 3 fatty acids linked to a 3-carbon molecule called glycerol
|
|
Oils
|
Polyunsaturated fatty acids
|
|
Ester Linkage
|
The type of link that joins glycerol to fatty acid molecules
|
|
Channel Protein
|
An ion channel that has a structure that permits only a particular type of ion or small molecule to pass through it; ex: aquaporins, which allow water to travel 10X faster across membrane than it does in absence of aquaporins
|
|
Phospholipid
|
A glycerol linked to a phosphate group & 2 fatty acid tails (hydrocarbon chains)
|
|
Secondary Active Transport (Cotransport)
|
Transport of an ion or molecule in a defined direction that is often against its electrochemical gradient, in company w/ an ion or molecule being transported along its electrochemical gradient
