Study Notes

Introduction to Metabolism and Lipids

Free model
  • Catabolism: Breaking down larger, complex molecules (like carbohydrates, fats, and proteins) into smaller ones. This process usually releases energy, which your cells capture, often in the form of ATP. Think of it as demolishing an old building to recycle its materials and power the demolition equipment.
  • Anabolism: Building up larger, complex molecules from smaller ones. This process usually requires energy input (often from ATP). Think of it as constructing a new building using those recycled materials, which takes effort and fuel.

Metabolism of Triacylglycerols and Glycerophospholipids

Free model

Lipids, especially triacylglycerols (TAGs) and glycerophospholipids (GPLs), are super important in metabolism. TAGs are the main form of energy storage in animals, providing a highly concentrated fuel source. GPLs are the fundamental components of all biological membranes, forming the lipid bilayer that defines cellular boundaries.

TAGs are made of a glycerol backbone esterified with three fatty acids. Their metabolism involves both synthesis (lipogenesis) and breakdown (lipolysis).
