Document Summary
All lipids share a property , not a structure. Tri acyl glycerol found in animal fat t vegetable oil. 3 fatty acids t glycerol chains long hydrocarbon. Glycerol : 3 carbons w/ oh group at each c fatty acids experience. Van der waals forces t carboxyl differ by : Proteins are often embedded in the with transporting molecules. Polar head can form h bond w/ water. Amphipathic pg 90 - 100 to help membrane. : bulkiness of head group - tails head. 7 no enzymes needed concentration (cid:8869) high (cid:8869) ph is of free phospholipids cell of a that close enough to less bulky head two hydrophobic tails a forms bilayer. I(cid:8869) head groups are ionized and hydrophilic in water liposomes. Lipids freely are dynamic other associate w/ each (cid:8869) weak and interactions reformed. , easily broken van der waals between tails forces. Fluid move in membrane my long fatty acid surface for tails.
