Sort the descriptions into properties that describe either saturated phospholipids or unsaturated phospholipids. Saturated phospholipids have straight fatty acid tails have no double bonds in the fatty acid carbon chains fatty acid tails pack tightly together produce a fairly inflexible membrane at low temperatures Saturated and unsaturated phospholipids maintain some space between adjacent phospholipids are built upon a glycerol backbone Unsaturated phospholipids have bent fatty acid tails contain one or more double bonds within the fatty acid tails allow the membrane to remain fluid and flexible at low temperatures
