A saturated triglyceride molecule is a lipid that consists of a glycerol backbone attached to three saturated fatty acids, which are fatty acids that have single bonds between all the carbons. On the other hand, a phospholipid molecule consists of a glycerol backbone attached to two fatty acids, some of which are unsaturated and contain one or more double bonds, and instead of a third fatty acid, the glycerol backbone in a phospholipid is bonded to a phosphate group with an attached charged molecule. Suppose a researcher successfully produced a membrane composed of saturated triglycerides rather than from phospholipids. What characteristics would you expect the saturated triglyceride membrane to have?
