You didn’t give us the actual options to choose from, but here’s everything I know about lipids:
1. They are naturally occuring.
2. Not soluble in water - they will not dissolve in water.
3. Fats (actually a subgroup of lipids) help the body absorb vitamin A, D, E, and K
4. Steroids are another subgroup of lipids.
5. Lipids are made up from the same elements that are in carbohydrates, but tend to contain higher amounts of hydrogen atoms than such.
