Study Notes
Lipid Groups and Functions
- Sterols, phospholipids, glycolipids, and fats are the four basic groups of lipids; proteins are NOT one of them.
- Lipids do not function as a catalyst for chemical reactions; they have various other functions such as energy storage, hormone regulation, and cellular structure.
Characteristics of Fatty Acids
- Fatty acids are characterized by having a hydrocarbon chain with a carboxyl group at one end, and they can be either saturated or unsaturated.
Triglyceride Molecule
- A triglyceride (TAG) molecule is composed of glycerol and three fatty acid chains.
LDL and HDL
- LDL (Low-Density Lipoprotein) is known as "bad" cholesterol, responsible for transporting cholesterol from the liver to peripheral tissues; it has a higher cholesterol content and lower protein content.
- HDL (High-Density Lipoprotein) is known as "good" cholesterol, responsible for transporting cholesterol from peripheral tissues to the liver; it has a higher protein content and lower cholesterol content.
