The structure of a lipid impacts its properties. — True
- Different lipid structures (saturated vs. unsaturated tails, head groups, ring vs. chain, etc.) determine melting point, polarity, membrane behavior, signaling roles, etc.
A gram of protein supplies more energy than a gram of fat. — False
- Fats supply about 9 kcal/g; proteins supply about 4 kcal/g, so fats provide more energy per gram.
Lipids are mostly hydrophobic. — True
- Most lipids are largely nonpolar (hydrocarbon chains or rings) and do not mix with water; some (e.g., phospholipids) are amphipathic with polar heads and nonpolar tails.
