are lipids polymers
no
what are lipids soluble in
organic solvents
what are lipids insoluble in
water
what is a triglyceride made up of
a molecule or glycerol and 3 fatty acid tails
what type of reaction joins the glycerol and fatty acid chains
condensation reaction
draw a glycerol molecule
glycerol
why is glycerol soluble in water
it has polar OH groups
draw a triglyceride and label the bond and R group
label
A) hydrocarbon chain
B) ester bond
what is the type of bond in a triglyceride
ester bond
what is a saturated fatty acid
a fatty acid which contains no carbon carbon double bonds (C=C) in the hydrocarbon chain
example of a saturated fatty acid
butter
what state are saturated fatty acids at room tepmerature
solids
what state are unsaturated fatty acids in at room temperature
liquids
what is an unsaturated fatty acid
a fatty acid which contains at least one carbon carbon double bond (C=C) in the hydrocarbon chain
what is an example of an unsaturated fatty acid
olive oil
what is a monounsaturated fatty acid
one C=C
what is a polyunsaturated fatty acid
more than one C=C
why is the fatty acid tails insoluble in water
hydrocarbon chain is non polar
describe the structure of a phospholipid
a glycerol molecule with a hydrophobic phosphate head attached and 2 hydrophilic fatty acid tails also attached
what does hydrophobic mean
water hating (non polar)
what does hydrophilic mean
water loving (polar)
what do many phospholipids form and where are they found
form a phospholipid bilayer which is the basis of cell membranes
