Learning Objective
I can describe the basic structure and function of lipids in living organisms.
- 1
The four main categories of lipids are triglycerides, phospholipids, steroids, and waxes.
- 2
Triglycerides are composed of a glycerol molecule bonded with three fatty acids through dehydration synthesis.
- 3
Phospholipids have a hydrophilic phosphate head and hydrophobic fatty acid tails, making them a major component of plasma membranes.
