Study Notes
Fats are a type of biological molecule important for energy storage and insulation in organisms.
- Fats — molecules made of glycerol and fatty acids Example: Butter and oils are common sources of fats.
- Glycerol — a simple polyol compound that forms the backbone of fats Example: Glycerol is combined with fatty acids to form triglycerides.
- Fatty Acids — long hydrocarbon chains that are components of fats Example: Saturated and unsaturated fatty acids are types found in foods.
