○ false

1. all of the following are functions of phospholipids except:

○ aid in digestion
○ act as an emulsifier
○ component of cell membrane
○ temperature regulation

Explanation:

1. Oxidation of fats in food leads to rancidity. Hydrogenation is the addition of hydrogen to unsaturated fats, oxygenation is related to adding oxygen in a different context, and fermentation is a process involving microorganisms.
2. Phospholipids are synthesized by the body but also need to be obtained from the diet to meet the body's needs.
3. Phospholipids aid in digestion as emulsifiers and are a component of cell - membranes. They do not play a role in temperature regulation.

Answer:
