Question

Phospholipids and triglycerides share the following features in A-D EXCEPT:

a. both have hydrophobic characteristics and are found in membranes

b. both contain ester bonds

c. both contain saturated or unsaturated fatty acids

d. both are synthesized from a common intermediate

e. all of the above are shared by both phospholipids and triglycerides

Answer 1

phospholipids contain two fatty acids attached to the OH group of the glycerol via an ester bond. and one OH group is attached to phosphate groups.

Triacyl glycerol contains three fatty acids attached to glycerol via an ester bond.

Phospholipids have a hydrophilic head group so phospholipids are found in membranes but triacylglycerol is not found in membranes.

fatty acids used in phospholipids or triacylglycerides can have double bonds, so the answer is a)  both have hydrophobic characteristics and are found in membranes.
