In this episode, we dive deep into the world of lipids—those hydrophobic molecules that play a critical role in cell structure and energy storage. From triglycerides to phospholipids and steroids, we break down their structure, function, and biological importance. Why don’t lipids mix with water? How do phospholipids form the basis of the cell membrane? And what makes saturated and unsaturated fats different at the molecular level? Whether you're cramming for the AP Bio exam or just want a clearer understanding of macromolecules, this is your go-to guide for mastering CED 1.5.
