Study Notes
Fatty Acid Metabolism
- De-novo synthesis of fatty acids primarily occurs in the liver.
- Primary sources of fats for lipid metabolism include dietary fats and de-novo synthesis.
Functions of Fatty Acids
- Fatty acids have various functions in cells, such as:
- Energy production through beta-oxidation
- Structural components of membranes and lipoproteins
- Signaling molecules and hormones
- Storage of energy in adipose tissue
Ketone Body Metabolism
- Ketone bodies are primarily used as an alternative energy source for the brain and other tissues when glucose is scarce.
- The significance of ketone body metabolism lies in its ability to provide energy during fasting, starvation, or low-carb diets.
Fatty Acid Synthesis
- The process of synthesizing fatty acids from non-lipid precursors is called de-novo lipogenesis.
- Examples of compounds synthesized using fatty acid intermediates include cholesterol, bile acids, and hormones.
Catabolism of Fatty Acids
- Catabolism of fatty acids through oxidation occurs in mitochondria.
- The major site for de-novo synthesis of fatty acids is the liver.
