Study Notes
Energy from Fats
- The brain does not use fats for energy.
Breakdown of Triglycerides
- Lipase is the main enzyme involved in breaking down triglycerides.
- Hormone-sensitive lipase (HSL) is stimulated by epinephrine (adrenaline) to break down triglycerides.
- When triglycerides are broken down, they release glycerol and fatty acids.
Lipolysis
- Glycerol is broken apart from fatty acids during lipolysis.
- Albumin is the transporter for free fatty acids in the blood.
Fatty Acid Transport
- Fatty acid-binding proteins are the primary transporters for fatty acids in muscle cells.
- Carnitine palmitoyltransferase I (CPT-I) is the enzyme that allows fatty acids to enter the mitochondria for energy production.
Fat as Energy Source
- Fats are primarily used for energy during rest because they provide a slow and steady release of energy.
- Fats are not the preferred fuel source during exercise because they are not quickly metabolized to produce energy.
