Ch 5 Lipid Structure and Function

amphipathic

has both hydrophilic and hydrophobic characteristics

saturated fatty acid tails

tails on a phospholipid that only have single bonds; all the carbons are saturated with four things attached to each one; solid at room temp

unsaturated fatty acid tails

tails on phospholipids that has one or more double bonds; liquid at room temp

increase

Do unsaturated fatty acid tails decrease or increase fluidity?

glycerophospholipids

phospholipids that contain a glycerol backbone bonded by ester linkages to two fatty acids and by a phosphodiester linkage to a highly polar head group

sphingolipids

have a sphingosine backbone instead of the glycerol backbone found in glycerol

ceramide

simplest sphingolipid with a single hydrogen atom as its head group

sphingomyelins

major class of sphingolipids that are also phospholipids
