Question
**Exercise 15.42:**

**Task:** Draw the condensed structural formula for the lecithin that contains glycerol, two palmitic acids, phosphate, and choline (ionized).

**Explanation:** In this exercise, you are asked to visualize the molecular structure of lecithin, a type of phospholipid. This requires an understanding of the components involved:

- **Glycerol** acts as the backbone of the molecule.
- **Two palmitic acids** are attached to the glycerol, forming diacylglycerol.
- A **phosphate group** is connected to the remaining hydroxyl group of the glycerol.
- **Choline** (in its ionized form) is attached to the phosphate group, completing the structure.

To illustrate this, start with the glycerol backbone, then add the fatty acid chains and phosphate-choline group as described. Remember to use chemical notation to depict condensed structural formulas.
