Lipids:
* Triglycerides: The primary form of stored energy in the body. They consist of three fatty acids attached to a glycerol molecule.
* Phospholipids: Major components of cell membranes. They have a phosphate group attached to a glycerol backbone, along with two fatty acid tails.
* Steroids: Include cholesterol and hormones like testosterone and estrogen. While steroids don't directly contain fatty acids, their synthesis involves fatty acid precursors.
* Waxes: Long-chain fatty acids attached to long-chain alcohols. They provide waterproofing and protection in plants and animals.
Other compounds:
* Glycolipids: Lipids with a carbohydrate attached. They play a role in cell recognition and signaling.
* Lipoproteins: Complexes of lipids and proteins that transport fats in the bloodstream.
* Eicosanoids: Signaling molecules derived from fatty acids, including prostaglandins, thromboxanes, and leukotrienes. They play crucial roles in inflammation, pain, and blood clotting.
It's important to note:
* Not all biological compounds contain fatty acids. For example, proteins, carbohydrates, and nucleic acids do not.
* Fatty acids are essential for many biological processes, such as energy storage, membrane structure, signaling, and protection.
