Answer:
Carbohydrates - made from sugars
Lipids - made from fatty acids
Proteins - made from amino acids
Step-by-step explanation:
For more details:
Carbohydrates
- Monomers are sugars
- Have linear structures
- Used for glucose storage
Lipids
- Monomers are fatty acids
- Hydrophobic
- Higher energy storage than glucose
Proteins
- Monomers are amino acids
- Make up 50% of the weight of the cell
- Several cellular functions (structural, storage, transport, hormonal, receptor, contractile, defensive, enzymes)
- Have primary, secondary, tertiary, and quaternary structures
Similarities
- All 3 contribute to storage
- Carbohydrates and lipids have energy storage
- Lipids and proteins both have lots of carbon-hydrogen bonds
- Proteins and carbohydrates have similar molecular makeup and give out 4 kcal per gram
