Q: What is a molecule with two fatty acids and a modified phosphate group attached to a glycerol backbone?


Read this paragraph and choose the correct option from the provided answers:

Figure 3.19 A phospholipid is a molecule with two fatty acids and a modified phosphate group attached to a glycerol backbone. The phosphate may be modified by the addition of charged or polar chemical groups. Two chemical groups that may modify the phosphate, choline and serine, are shown here. Both choline and serine attach to the phosphate group at the position labeled R via the hydroxyl group indicated in green.

 Choices:

- carbohydrate

- polymer

- amino acid

- phospholipid
