lipids

macromolecules grouped together they are hydrophobic

mostly hydrocarbons/nonpolar covelant bonds

• glyerol head
• 3faty acid tails

maximum of number of hydrogens attached to each c

no bend in tails

higher meltin point tail closer together

• glycerol head
• 3fatty tails
• at least one tail has a double covelant bond between c

tails bent

low melting temperature

fatty tail that has more than one covelant bond between the c

• glycerol section
• fatty acid chain
• phosphate group

one end hydrophobic and end is hydrophilic

water added self assemble into a bilayer with hydrophobic tails pointing toward he interior

• arrangement found in cell membranes
• major component of all cell membranes
