Study Notes
- Cholesterol is a building block for hormones, bile salts, and vitamin D.
- Insulin promotes energy storage as triglycerides, while adrenaline and glucagon promote fat breakdown.
- Glycerol-3-p is required for fat breakdown, and activated acyl groups are needed for transport to the mitochondria for oxidation.
- Acetyl groups are building blocks of cholesterol, and cholesterol synthesis involves several steps.
- Plants use photosynthesis to make starch, while animals use fats and triglycerides for energy.
- Coenzyme A is necessary for fat synthesis and degradation, and acyl CoA is the activated form of fat.
- Vitamin D synthesis involves several steps, including exposure to UV light.
- LDL and HDL are lipoproteins that carry cholesterol and other lipids in the blood.
- HMG-CoA reductase inhibitors reduce cholesterol levels and risk of cardiovascular disease.
- Desirable levels of serum cholesterol and triglycerides vary depending on risk factors and presence of CHD.
