Study Notes
- Lipids are essential components of every cell membrane in living organisms.
- They are part of the phospholipid membrane that acts as a boundary for cells.
- Lipids include not only fats but also oils, waxes, and steroids.
- Steroids such as cholesterol and hormones like testosterone and estrogen are lipids.
- Lipids are large organic macromolecules made up of carbon, hydrogen, and oxygen.
- Monomers called fatty acids form lipids through chemical bonds.
- Saturated fatty acids have single bonds between carbon atoms, making them solid at room temperature.
- Unsaturated fatty acids have double bonds between carbon atoms, making them liquid at room temperature.
- A lipid polymer called a triglyceride forms when three fatty acids bond to a glycerol molecule.
- Saturated triglycerides contain only saturated fatty acids, while unsaturated triglycerides have unsaturated fatty acids.
- Lipids play various roles in living organisms, including cell membranes, long-term energy storage, insulation, and hormone formation.
