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